GHL SERIESGEL BATTERIES GEL SEALED VRLA BATTERY LONG LIFE 12 YEARS OF EXPECTED LIFETIME Nominal Operating Temp. Range Cycle Application 1. Limit initial current less than 27.0A. 2. Charge until battery voltage (under charge) reaches 14.1V to 14.4V at 25°C(77°F). 3. Hold at 14.1V to 14.4V until current drop to under 0.81A for at least 3 hours. 4. Temperature compensation coefficient of charging voltage is -30mV/°C. Standby Service 1. Hold battery across constant voltage source of 13.6 to 13.8 volts with current limit 27.0A continuously. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charge status. 2. Temperature compensation coefficient of charging voltage is -18mV/°C. Operating Temperature Wide operating temperature range from -20°C~55°C NOTE : The battery should be charged within 6 months of storage, Otherwise, permanent loss of capacity might occur as a result of sulfation
