Charging Methods

Application	Charging method	Charging Voltage  at 25°C	Temperature compensation coefficient of charging voltage	Max.charging current	Charging time  25°C(h)		Temp (°C)
					100% discharge	50% discharge
For standby power source	Constant voltage & Constant Current  Charging  (with current restriction)	13.5~13.8V	-20 mV/°C	No limit on Initial Charging Current	24	20	0~40 (32~104°F)
For cycle service		14.1~14.4V	-30 mV/°C	62.5A	16	10

*Temperature compensation of charging voltage is not needed.when using the batteries within 15°C to 35°C range.
