Cycle Application

Limit initial current less than 50.0A.
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 under 1.44A 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 50.0A 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.
