Minimum Voltage: This is the cut-off voltage we need to set to prevent over-discharging the NiMH battery.

Nominal Voltage: This is the average voltage of the NiMH battery under normal working conditions.

Fully Charged Voltage (Max. Voltage): This is the target voltage to set when charging the NiMH battery.

Proper Use of NiMH Batteries

Discharging: During use, monitor the battery temperature. If the battery gets too hot, it indicates high internal resistance, and you should stop using it and replace it with another battery.

Charging: If you have time, charging at 0.2C is the safest. For faster charging, you can set it to 1C.

Storage: Since NiMH batteries have a good self-discharge characteristic, you don’t need to pay special attention to the storage voltage. However, it’s best to store them at 30% to 50% charge for long-term storage.
