Johnson & Associates, Inc. 1211 Connecticut Avenue, N.W., Suite 302 Washington, D.C. 20036-2603 Dear Mr. Noone: This is in response to your letter of March 25, 1997, requesting clarification on the shipping requirements for batteries manüfactured by your company under the provisions of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if your batteries are subject to the HMR. The information you provided demonstrates that your batteries are constructed in such a manner that the sulfuric acid electrolyte is completely sealed and cannot leak even if the battery is cracked open or punctured. In addition, the sulfuric acid electrolyte is absorbed in a fibrous glass separator. Thus, your batteries appear to meet the criteria for non-spillable batteries in § 173.159(d). When securely of the Hazardous Materials Regulations. packaged and protected against short circuits, non-spillable batteries are not subject to the provisions In addition, under the International Civil Aviation Organization's (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air, special provision A67, a non-spillable battery is considered to be non-regulated if, at a temperature of 55°C, the electrolyte will not flow from a cracked or ruptured case. I hope that this information is helpful. If you need further assistance, please contact us. Sincerely, i Chich Re Baliness Chief, Regulations Development Office of Hazardous Materials Standards#

Suzanne Hedgepeth Director Office of Hazardous Materials Exemptions and Approvals Office of the Associate Administrator For Hazardous Materials Safety Research and Special Programs Administration Department of Transportation 400 Seventh Street, SW Washington, DC 20590 Re: Request for Determination Dear Ms. Hedgepeth: I am writing to seek an updated determination from the U.S. Department of Transportation ("DOT") that batteries manufactured by OPTIMA Batteries, Inc. ("Optima"), of Aurora, Colorado, are not subject to the Hazardous Materials Regulations and, therefore, can be shipped commercially by air and surface means without restriction. Optima utilizes a spiral design for battery cells that was originally developed by The Gates Rubber Company ("Gates") of Denver, Colorado. The technology was invented by Gates in the 1970s, and commercial production began in 1987 under the Optima name. In 1990, Optima was incorporated as a division of Gates. In 1992, Optima was purchased from Gates by The Gylling Group of Scandinavia, the current parent company. This history of Optima is outlined in "The Optima Manual," Attachment A. In 1981, in response to a request by Gates, the Research and Special Programs Administration ("RSPA") of DOT informed Gates that because of the sealed design of the batteries eventually to be sold under the Optima name, such batteries were not subject to the Hazardous Materials Regulations. See Attachment B, letter of February 18, 1981, from Joseph T. Horning, Chief, Regulations Development Branch, Office of Hazardous Materials Regulations, Materials Transportation Bureau, RSPA.

Page 163. HISTORY OF THE OPTIMA BATTERY 1973 Gates Rubber Company, one of the world's largest producers of rubber products for the automotive industry, develops the initial battery technology incorporating a SPIRALCELL with recombinant technology. The company produces millions of battery cells for tools, appliances, and emergency lighting. i 1983 Gates recognizes the need for an advanced automotive battery. The company begins research and development to further explore the battery technology. 1984 The S.L.I. (Starting, Lighting, Ignition) battery project team is established at Denver, Colorado. 1987 Limited S.L.I. production begins; the first automotive batteries go to market. 1990 Gates incorporates the division as OPTIMA Batteries, Inc. Gylling Teledata A/S of Norway begins limited importation and distribution of OPTIMA batteries. Soon after, Gylling obtains distribution rights for all of Scandinavia. 1991 Gates divests itself of OPTIMA Batteries, Inc. 1992 The Gylling Group of Scandinavia purchases OPTIMA Batteries, Inc. from Gates. 1993 Public demand for the OPTIMA battery begins to rapidly increase. 1994 OPTIMA Batteries, Inc. breaks ground for a new, larger, modern manufacturing facility in Aurora, Colorado. 1995 OPTIMA Batteries Inc. moves into its new headquarters in Aurora, Colorado. Sub-contract with General Motors is signed to develop a monoblock battery for their hybrid vehicles. 1996 Full production begins at new facility and sales efforts expand throughout the North and South America as well as world-wide.

Using unalloyed lead extends the life of the OPTIMA grid will resist corrosion and last longer OPTIMA battery by reducing grid corrosion. The As a result, the battery loses capacity and power. With age, the grids shed their active paste material. in high temperature environments. engines are harder to start and in cold temperatures. This power loss becomes especially noticeable when While conventional batteries are adversely affected by heat, the effects of heat on a high purity lead Using alloys in the grid sacrifices performance for OPTIMA battery are minimal. and paste adherence but lowers electrical strength.

This shortens the battery's life considerably. Another advantage of using the high purity lead is a low self-discharge rate. The alloys in conventional material and the grid, causing a loss of electrical batteries accelerate the reaction between the active charge. (See Figure 2) (See Figure 1) August 14, 1996#

Page 42- 10. INAPPROPRIATE USES OF OPTIMA S.L.I. BATTERIES The OPTIMA S.L.I. battery is not recommended for the following applications: CYCLE SERVICE APPLICATIONS (DEEP CYCLE) OPTIMA S.L.I batteries are not suitable for electric power applications that must withstand repeated deep discharges such as in wheelchairs, golf carts or forklifts. (You must use OPTIMA's deep cycle battery for this type of application.) Cycle service (traction) batteries require thick plates because they must deliver lower amperage for a long period of time. S.L.I. batteries have thin plates that cover a greater surface area, making them able to deliver high amperage for short periods. For example: S.L.I. An S.L.I. battery must deliver 250 to 350 amps for a few seconds to start a vehicle. It is typically used to power vehicle accessories such as lights and windshield wipers for a few minutes while driving slowly or during short trips. This load is usually about 10 to 25 amperes. The average depth of discharge for an S.L.I. battery is approximately 2% to 3% of its capacity. Deep cycle In a deep cycle application such as a trolling motor, the battery may need to deliver 15 amps for a couple of hours. The average depth of discharge is typically 60% to 70% or more of the battery capacity. When an S.L.I. battery is used in deep cycle applications, its life will be greatly reduced. Deep cycling an S.L.I. battery will hasten decomposition of the active material on its plates While the OPTIMA is not designed for these deep discharges, it will outperform conventional S.L.I. batteries under deep discharge conditions. For RV applications, battery requirements depend on individual conditions. The OPTIMA S.L.I. performs well during moderate use requiring frequent, shallow discharges. This is sometimes referred to as "wet-camping"; an R.V. owner parks at a facility where the vehicle can be plugged into an electrical power source. Most of the accessories are then powered by the external source. Applications requiring repeated deep discharges are best handled by batteries designed for this use, such as the OPTIMA Deep Cycle battery. Regardless of the application, the total capacity of the replacement batterys) should meet or exceed the average load requirements. 29 August 14, 1996#

Page 4311. QUALITY CONTROL IN ACTION - THE FINISHING LINE OPTIMIA Batteries, Inc. prides itself on the quality of its batteries. Every unit leaving the production facility has undergone many strenuous tests to ensure that it is the highest quality battery that can be produced. Every battery manufactured at OPTIMA is subjected to a computer monitored, fully automated, five-stage quality test. This assures that our customers receive the highest quality, battery on the market. No other S.L.I. battery manufactured in the United States has such high quality standards. As each battery moves through the line, it is tracked by a computerized bar code system that records and stores the date, lot number, work shift and battery number. This information is then combined with the test results as described below. the Test Lab for analysis. Any battery that fails to meet specifications in the following system is "kicked out" and sent to OPTIMA QUALITY TESTING PROCEDURES: 1. O.C.V. (Open Current Voltage). This test measures the existing voltage in the battery and detects those which do not receive a proper formation (formation is the initial charge applied to a battery during the manufacturing process). 2. LOAD TEST. A 1200-1400 ampere load test is applied to each battery to check strap (intercell connector) integrity. This detects weaknesses in the strap such as cracks, shorts and/or poor strap to cell bonding. 3. VOLTAGE UNDER LOAD. During the load test, the voltage is measured and recorded. Voltage • expectancy. analysis testing and statistical modeling has enabled OPTIMA to accurately predict battery life 4. INTERNAL RESISTANCE. Low resistance translates to greater cranking power for engine starting and quicker charging. Resistance readings also detect various manufacturing defects. 5. WEIGHT. During the last stage, each battery is automatically weighed to verify the correct acid to lead relationship. Quality control is evident throughout the entire OPTIMA manufacturing process. In addition to the five step quality process described above, every stage of production is monitored for quality of material and accuracy. Also, due to the sealed design of the OPTIMA, every battery made is checked for case integrity. After the top cover is sealed, each battery is pressurized with air and submerged in water. If the battery were to have any leaks they become immediately evident. 30 August 14, 1996#

Page 4412. RATING OF S.L.I. BATTERIES batteries. Reserve Capacity and Cold Cranking Amps are the industry standard measurements for S.L.I. Reserve Capacity (R.C.) - Time in Minutes: This test measures, in minutes, how long a battery can maintain a minimum of 10.5 volts (at 80°F) while being discharged at 25 amps. The R.C. rating is especially important for emergency situations such as in the case of alternator failure. Cold Cranking Amperes (C.C.A.) - Power: The primary function of an S.L.I. battery is to start the engine. Since starting is increasingly difficult as the temperature drops, the best measurement is the amount of power a battery can deliver in cold temperatures. This unit of measurement is called C.C.A. (Cold Cranking Amps). C.C.A. is measured in accordance with the S.A.E. (Society of Automotive Engineers) standards. It (1.2 volts per cell). measures how much current can be delivered for 30 seconds at 0°F (-18°C) while staying above 7.2 volts Cranking Amperes (C.A.): C.A., sometimes referred to as Marine Cranking Amps (MCA), measures how much current can be delivered for 30 seconds at 32°F (0°C) while staying above 7.2 volts. Formerly, the measure of a battery's electrical storage was Ampere-hour (amp-hr). It was determined by multiplying the current in amps by the time of discharge. Example: A battery that delivers been replaced by C.C.A. and Reserve Capacity (R.C.). 5 amperes for 20 hours (5 amperes times 20 hours), has a 100 amp-hr capacity.

Page 4513. BASIC BATTERY TECHNOLOGY AND TERMINOLOGY battery are quite complicated. On the surface, battery technology appears simple. However, the electrochemical reactions within a A. WHAT IS A BATTERY? A battery is an energy storage device that converts chemical energy into electrical energy. The electrochemical reactions involve the transfer of electrons from one material to another through an external electrical circuit and the motion of ions in an internal medium (the electrolyte). While the term "battery" is often used, the basic electrochemical unit is the "cell." A battery contains one or more cells, connected in a series, parallel, or both, depending on the desired output voltage and/or capacity. A cell consists of three major components: • Electrodes: more commonly called plates. Each cell requires at least one positive and one negative electrode. Cells may contain multiple electrodes. • Electrolyte: typically a liquid that provides the medium for the transfer of charge, as ions, between electrodes inside the cell. • Separator: a divider between the positive and negative plates which allows the current to flow through it. The separator prevents the positive and negative plates from contacting each other and causing an electrical short. Separators are typically made of glass material, plastic, or a void (space between plates). When the battery is discharged, the negative plate reacts, transferring electrons to the external circuit (head lights, starter motor, etc.). To complete the circuit, the positive plate reacts, accepting electrons from the external circuit. When the battery is being recharged, a similar process occurs in reverse order. battery has the genera Case hydro be vended to en eve inates prescel This ne ors during the replaced regularly. If the gasses are not vented, they must be recombined as water inside the cell (as with sealed batteries such as the OPTIMA). 32 August 14, 1996#

Page 46B. VARIOUS TYPES OF BATTERIES Different materials can store energy and the names of batteries often identify their active materials such as Nickel-Cadmium, Nickel-Iron, and Lithium-Ion. Other batteries are named for the type of material found in the plates and the type of electrolyte system used; the most common is the lead-acid battery. Batteries are classified in two ways. They are either rechargeable (also called secondary) which can be recharged repeatedly, or non-rechargeable (also called primary) which consist of single cells usually configured as flat buttons or cylinders for one time use. Various types of electrolytes are used in batteries. The lead-acid based battery uses sulfuric acid electrolyte (HI,SO,), while alkaline-based batteries, such as nickel-cadmium, use potassium hydroxide (KOH). the plates. Most large lead-acid batteries are "flooded cell" batteries with large reservoirs of electrolyte covering Some lead-acid batteries are named for their electrolyte systems such as "gel cells" and "absorbed electrolyte". Gel cells use electrolyte in a gel form instead of a free flowing liquid electrolyte. Absorbed electrolyte batteries (such as the OPTIMA) have the electrolyte retained by the absorbent separator material between the plates, preventing the electrolyte from flowing freely. The trade-offs in performance, weight, volume, cycle life and cost dictate the need for many battery types. No one battery system can meet all the needs of all users. Lead-acid Batteries Lead-acid batteries were first manufactured in the mid 1800s when scientists found that lead immersed in a sulfuric acid solution produced an electric voltage and could be recharged. Lead-acid batteries are unique because they typically use inexpensive lead for both the negative and positive plates. Despite extensive research into alternative technologies, lead-acid batteries are still the most prevalent today. Their popularity and widespread use are largely due to the following benefits: Wide temperature range for cycling and non-cycling operations Low cost materials Ready recycling of lead and other components Reliability • Proven manufacturing process High power density 33 August 14, 1996#

Page 47In a lead-acid battery, the active material reacts with the electrolyte to produce the chemical reaction that creates electrical energy. The active material in the positive plate is lead dioxide (PbO,) and the negative is pure spongy lead (Pb). The electrolyte is sulfuric acid (H_SO,). When we talk about the active material in lead-acid batteries, we mean the lead dioxide and spongy lead. Lead dioxide and spongy lead are made into paste and applied to lead grids. This grid is not active material but acts as the electrical conductor or path to cell terminals. In most designs, the grid provides mechanical strength to support the active material in the cell. C. WHAT HAPPENS INSIDE A LEAD-ACID BATTERY? In most cell designs, the plates are immersed in a free liquid acid. In sealed cells, the acid is absorbed additive (gel-cell technology). completely in the plates and separator structure (absorbed acid technology) or converted to a gel by an All lead-acid batteries have the same general overall chemical reaction for charge and discharge. → → → Discharge cycle Charge cycle On discharge, the lead dioxide (PbOz) of the positive electrode and the spongy lead (Pb) of the negative electrode are both converted to lead sulfate (PbSO.). On charge, the lead sulfate in the positive electrode is converted to lead dioxide (POz), which then converts to oxygen on overcharge. The lead sulfate sponge lead in the negative electrode is converted to spongy lead, which then converts to hydrogen on overcharge. The electrolyte, sulfuric acid (H,SOA), is an active component in the reactions at both plates. If a flooded type battery is overcharged, oxygen gas is generated at the positive electrode. Gas bubbles rise to the surface and escape from the cell. At the same time, hydrogen gas is generated at the negative electrode and also escapes from the cell. The overall result is water loss which must be replaced periodically. In the OPTIMA battery, during charge, oxygen combines with the freshly formed lead at the negative electrode in the presence of H,SO4, to form lead sulfate and water. This oxygen recombination prevents hydrogeri from forming at the negative electrode. Therefore, there is no water loss during charging. 34 August 14, 1996#

Page 48Electrolyte: The electrolyte in the lead-acid cell is a solution of sulfuric acid (H,SO,) and water. It plays an active role in the chemical reactions that convert energy within the cell. Changing the density (specific gravity) of the acid solution affects performance factors such as capacity, maintenance, and battery life. Table 1 (below) shows the relationship between acid specific gravity and battery capability. Battery: Acid specific gravity capacity Maintenance of Battery life battery (longevity) Higher Increase Increase Decrease Lower Decrease Decrease Increase Table 1 The effect of specific gravity on battery performance A fully charged conventional battery at 80°F (26.7°C) has electrolyte with a specific gravity of 1.265. Because the OPTIMA is completely sealed, it does not lose water during the charging cycle as does a conventional battery. Within the OPTIMA, a measured amount of electrolyte is absorbed in the separator material between the plates. It is the precise amount to generate chemical reactions that optimize battery capacity and life. Plate Materials calcium. In a conventional battery, the lead grid must be strengthened with alloys such as antimony or While alloys add mechanical structure, they increase the rate of corrosion within a battery. More alloys are added to counteract this corrosion. This decreases the battery's performance. Antimony improves castability, mechanical properties, and paste adherence, but reduces the grid's electrical conductivity and increases self-discharge. Antimony can be completely eliminated from the battery by hardening the lead with a small amount of calcium. Some non-antimony alloys are an improvement, offering a longer shelf life and good cold crankins haracteristics. Still, while tin-calcium grids reduce the tendency of lead calcium positive plates to resist recharge when deeply discharged, they do not completely eliminate corrosion. OPTIMA batteries use high purity lead for a long life, high cranking capability, low self discharge and maintenance free operation. The physical design of the plates and the SPIRALCELL configuration strengthen the OPTIMA without alloys. 35 August 14, 1996#

Page 49D. IYPES OF LEAD-ACID BATTERIES Lead-acid technology can be varied to meet different requirements. Batteries are classified according to their applications and their designs differ in three major ways: plate structure and design, composition of the active material, and the specific gravity of the electrolyte. Applications for lead-acid batteries fall into three broad categories: • Standby (Float) Service • Cycle Service • Starting/Lighting/Ignition (S.L.I.) • Standby (Float) Service Standby battery systems provide an uninterrupted supply of power to an electrical load component. They discharge immediately when primary (AC) power is interrupted. The electrolyte and electrode grid material are designed for long term service life. Typical standby applications include emergency lighting. and computer backup. • Cycle Service Batteries in cycle service are used as primary energy sources for applications such as: Backup power for devices in photovoltaic systems. • Electric vehicles such as fork lifts and golf carts. Recreation vehicles. • Trolling motors. • Wheelchairs. In each of these applications, the battery is the primary energy source. It must deliver sufficient power to the vehicle or device before requiring recharge. The number and depth of cycles limits the life of these batteries; hence, their life is expressed in cycles rather than years. These batteries are subject to a constant, relatively low rate of discharge over a long period. Cycle service batteries typically have very thick plates with heavy duty grids to provide as many cycles as possible. • Starting/Lighting/Ignition (S.L.I.) : S.L.I. batteries are primarily used for starting internal combustion engines. Their duty cycle is characterized by a short discharge at a very high current, immediately followed by recharging. During a normal start, the battery loses very little capacity. S.L.I. batteries also operate lights, radios, and other equipment for short periods without running the engine or when the engine is operating at low speeds (idling). S.L.I, batteries can keep the engine running for a short time if the alternator fails. 36 August 14, 1996#

Page 50- To start engines, the battery must produce high power for short durations. This capacity is designed into the S.L.I. battery via increased plate surface area and heavy-duty intercell connectors. 14. GENERAL CHARGING PROCEDURES When a lead-acid battery is charged by connection to an external power source, the electrons flow in the opposite direction of that used in discharge. For this to happen, the outside power source must generate a higher voltage than the battery. An example of recharging the battery with a vehicle alternator is shown graphically in Figure 8. In this example, the voltage limit is set at 14.4 volts and the alternator supplies 25 amps. The battery initially accepts the full 25 amps. Voltage increases proportionally to 13.9 volts as the battery becomes recharged. When the battery is fully charged, the current is reduced to less than one amp. The excess batteries, the gas escapes, allowing the battery to dry out. In a recombinant battery such as the nergy from the charge is converted into gas in ALL lead-acid batteries. In conventional floodec OPTIMA, the gas recombines with the electrolyte to form water.

Page 51The charge curves in Figure 8 illustrate the relationship between voltage and current for the OPTIMA battery. In a properly functioning charging system, the battery will begin to limit charge current as it becomes fully charged. Voltage increases proportionally to the percent of the battery charge. General guidelines for charging lead-acid batteries depend on the type of charging system being used. A. Charging with a Vehicle Alternator: An S.L.I. battery is usually charged by the vehicle's alterna- tor. An alternator setting of approximately 13.2 to 14.4 volts for automobiles in the United States will usually assure proper battery performance. Exceeding this voltage for long periods can overcharge the battery. When this happens the battery will gas excessively, lose electrolyte, and dry out the plates, deteriorating the active material and shortening life. Vehicles are generally equipped with voltage- regulated charging systems which allows the battery to reduce the amount of current it accepts as it becomes fully charged. Most vehicles also have temperature compensating regulators which automatically decrease the voltage setting as temperature increases. Thus, overcharging an S.L.I. battery in a vehicle with a properly working charging system is rare. The way a vehicle is operated can also impact the effectiveness of the charging system. The following paragraphs describe typical charging conditions for passenger vehicles and commercial vehicles such as taxis. Passenger Vehicles High electrical power consumption and frequent short trips require a higher alternator voltage to recharge the battery more quickly. Long trips require a lower voltage. Owners generally use their cars for both long and short trips, requiring an alternator setting of about 14.4 volts. Commercial Vehicles Taxis and similar vehicles driven short distances are usually equipped with a high output alternator which produces a charging voltage between 14.4 and 14.8 volts. A higher output alternator is required to fully charge the battery during short trips. B. Charging with an External Charger Batteries used in non-automotive applications or a battery that has been inadvertently discharged and can no longer start the car must be recharged. A charger with voltage regulation is necessary to charge an OPTIMA battery. The regulated charging system will detect the degree of charge needed and adjust its charge rates accordingly (see Figure 8). The OPTIMA battery can be charged with a bench charger. We suggest a voltage setting range of 13.8 to 14.8 volts and a suggested current output of 10 amperes. At 10 amps, a completely discharged battery will be fully recharged in 5.5 to 6 hours. 38 August 14, 1996#

Page 52C. Recommended charging limits for OPTIMA batteries: • Normal recharge: Voltage - 13.8 volts to 14.8 volts Maximum available current - 10 amps • Float applications: Voltage - 13.2 volts to 13.8 volts Maximum available current - 1.0 amp Maximum recharge time - Indefinite at lower charge voltages. ! (The OPTIMA battery is not designed or recommended for float applications although many customers have successful used it for this purpose.) • Boost recharge: Voltage - 15.6 volts maximum Maximum available current - 60 amps Maximum recharge time - 1 hour or when the battery starts to get hot. D. Problems Caused by Incorrect Charging Procedures Overcharging is a common problem caused by continuing to charge the battery after it has been filly charged. The following conditions will occur when a battery has been overcharged: Oxy-hydrogen Gas: In a conventional battery, overcharging causes hydrogen and oxygen to build up and escape faster than normal. Since these gasses can form explosive oxygen and hydrogen, conventional batteries must always be charged in a well-ventilated area. With proper charging recombination batteries are not as susceptible to loss of water. Their ability to recombine gases into water reduces gas build up. If overcharging occurs (usually from an unregulated charger or failed vehicle charging system), more gas may be generated than can be recombined. The pressure from this excess gas will eventually cause the safety valves te release, allowing gas to escape; the valves will then reseal. A hissing or whistling noise signals that pressure is being released. If this happens, immediately disconnect the battery from the charging system. If enough electrolyte is lost, battery performance will be reduced, similar to conventional S.L.I. batteries. Generally this happens to the OPTIMA battery only when it has been abusively overcharged. However, unlike conventional batteries, it is not possible to replace the water in the OPTIMA battery and the abusive overcharge can damage it permanently. Any battery that feels very warm or if the case is visibly damaged or distored should be removed from charging immediately. Appendix A). When an OPTIMA battery overcharge is suspected, weigh the battery (see the warranty procedures, Electrode Damage: When gassing occurs within a battery, water is evaporated from the electrolyte, reducing its volume and increasing its density (specific gravity). If enough water is lost, the active material on the plates is exposed to air. This will accelerate sulfation of the active material, leading to battery failure. Distilled water is usually added to a conventional battery to make up for loss during overcharge. The OPTIMA battery does not lose water unless it has been abusively overcharged. 39 August 14, 1996#
