Recharge Method
: Connect battery to a Current Limited, Constant Voltage Source.
Limit the initial recharge current to 2.75 Ah or less.
To promote satisfactory performance in Cyclic applications, a minimum recharge current of 1.1 Ah 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)
