How to Extend the Service Life of Ni-MH Battery in Daily Use and Storage?

Standard usage and storage methods can effectively prolong the service life and capacity retention of Ni-MH Battery, lowering equipment maintenance and replacement costs.

Daily Usage Guidelines

·         Matched Charger: Do not use high-speed chargers or non-specialized chargers. Improper charging will cause overheating, bulging and permanent performance loss.

·         Avoid Over-discharge: Do not recharge the battery until the device shuts down completely. Long-term over-discharge will damage electrodes and reduce capacity permanently.

·         Mixed Use Prohibition: Do not combine batteries with different capacity, brands or service ages. Uneven voltage will lead to abnormal performance and potential risks.

·         Anti-short Circuit & Anti-collision: Keep electrode terminals clean and rust-free. Prevent metal objects from contacting positive and negative poles to avoid short circuit and equipment damage.

Long-term Storage Requirements

Ni-MH batteries have a monthly self-discharge rate of about 5%. Please follow the official storage standards below for long-term preservation.

·         Ideal Charge Level: Charge the battery to around 80% before long-term storage. Avoid keeping batteries fully charged or fully drained to slow down material aging.

·         Storage Environment: Place batteries in a cool, dry and ventilated area, away from high temperature, direct sunlight and humid conditions.

·         Reactivation after Storage: If the battery is stored for more than six months, perform a slow charge before use to restore activity and rated capacity.

·         Moisture Prevention: Humid environment may cause electrode oxidation and poor contact. Use moisture-proof boxes or desiccants to further extend storage life.
