Salient characteristics. The product shall be a 6 volt (normal or reversed) , 200 ampere-hour sealed lead-acid storage battery, meeting the requirements specified below.

1. Dimensions. The maximum dimensions for the battery shall be:

2. Weight. The battery weight shall be 144 pounds maximum when filled.

3. Terminals. The terminals shall be posts with lugs capable of receiving a round end lug accepting an AWG #0000 cable.

4. Pressure relief valve. The battery shall have sufficient pressure relief valves to prevent rupturing of the battery when internal pressure exceed battery design pressure.

5. Capacity.

a. The capacity for the 20 ampere (or 10 hour) rate shall be a minimum of 200 ampere-hours with a cut-off voltage of 10.5 volts in the temperature range of 20° to 27° C.

b. The capacity for the 65 ampere (or 2 hour) rate shall be a minimum of 130 ampere-hours with a cut-off voltage of 4.8 volts in the temperature range of 20° to 27° C.

c. The capacity for the 480 ampere (or 5 minute) rate shall be a minimum of 40 ampere-hours with a cut-off voltage of 3.6 volts in the temperature range of 20° to 27° C.

6. Reserve capacity. The battery shall deliver 25 amperes for a minimum of 60 minutes at 25^oC with a cut-off voltage of 10.5 volts.

7. Cold cranking Performance at -18°C (O°F). The battery shall deliver 1100 amperes for a minimum of 30 seconds at -18°C with a cut-off voltage of 3.6 volts per cell times the number of cells.

8. Retention of charge. The battery shall retain at least 80% of the 10 hour-rate capacity (200 ampere-hours) 28 days after charge termination when discharged at the 10 hour rate.
