Feature Diagram of Ni-MH and Ni-Cd Batteries

A.Charging

We recommend standard charging the battery at 0.1c for 15 hours. Or quick charging at1.0c for 1.2-1.5 hours. During quick charging, we recommend the charger equipped with voltage cut-off(-△v)control and/or temperature sensor to protect battery.

B.Discharge

The available capacity of a rechargeable battery depends on the discharge current, ambient temperature and the cut-off voltage. A battery can be discharged at 0.2c upto 5c.
