Cycle Application
- Limit initial current less than 18.75A.
- Charge until battery voltage (under charge) reaches 14.1V to 14.4V at 25ºC(77ºF).
- Hold at 14.1V to 14.4V until current drop to under0.45A for at least 3 hours.
- Temperature compensation coefficient of charging voltage is -30mV/ºC.
Standby Service
- Hold battery across constant voltage source of 13.6 to 13.8 volts with current limit 18.75A continuously .When held at this voltage , the battery will seek its own current level and maintain itself in a fully charge status.
- Temperature compensation coefficient of charging voltage is -18mV/ºC.
