Batteries are rated in ampere-hours (Ah) and are designed to perform a specific workload within an established period of time. Increasing either and/or both of these will over-discharge the batteries and result in shortened life.- Limit discharging the batteries beyond 1.75 volts per cell - or 1.125 specifice gravity per cell. 1.75 volts per cell corresponds to end-point voltages of 5.25 volts for 6-volt batteries, 7 volts for 8-volt batteries and 10.5 volts for 2-volt batteries.
- Batteries should always be recharged immediately following a complete discharge period. Never allow batteries to remain in a fully discharged condition,m otherwise permanent damage will result.
- If daily or routine equipment operation results in only partial discharges (40% or less) and specific gravities are 1.225 or higher, recharging may be deferred to the next day, providing the workload is not expected to increase. Grenerally, user experience will determine the frequency of charging service under these circumstances.
- Under normal circumstance the temperature of the battery electrolyte must not exceed 110o F (43o C). If the battery is continuously operated at or above this point the service life of the battery will be severely diminished. Under normal conditions, battery electrolyte condition should range from 60o to 100o F (15o to 38o C). After charging, the battery should be allowed to cool-down or rest from 6 to 8 hours before the next discharge cycle begins.
- If a battery is ever hot to the touch, allow it to cool to ambient temperature before charging or discharging.
- Keep battery connectors and cabling in good condition. When disconnecting the battery connector from the equipment, pull on the connector - not the cable. Damage to the connectors and/or cables will result in poor battery performance.
