Recharge Method: Connect battery to a Current Limited, Constant Voltage Source. | ||||
Limit the initial recharge current to 1.25 Ah or less. To promote satisfactory performance in Cyclic applications, a minimum recharge current of 500 mA is recommended. Employ Charge Voltage Temperature Compensation when battery temperature is less than 50°F (10°C) 0r greater than 86°F (30°C), Use the Recommended voltage and normalize to 77°F (25°C). The use of compensation through the whole temperature range is not generally necessary, but doing so may optimize service life. If the Recommended recharge voltage is used, no Temperature Compensation is required within the range of 50 ~ 86°F (10 ~ 30°C) | Cyclic Application Recharge Voltage (77°F / 25°C) | |||
