Cycle Application

Limit initial current less than 1.2A.
Charge until battery voltage (under charge) reaches 4.70V to 4.80V at 25ºC (77ºF).
Hold at 4.70V to 4.80V until current drop to under 0.027A for at least 3 hours.
Temperature compensation coefficient of charging voltage is -10mV/ºC.

Standby Service

Hold battery across constant voltage source of 4.54 to 4.60 volts with current limit 1.2A 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 -6mV/ºC.
