How do I charge a NiMH battery?

The best way to charge a NiMH battery is by using a suitable charger that is specifically designed for NiMH technology. These chargers provide a controlled charging current and automatically shut off once the battery is fully charged, preventing overcharging. They are commonly used to recharge NiMH AA and AAA batteries.

Fast chargers can charge the battery in a few hours but put more stress on the cells due to increased heat generation. Standard chargers take longer but are gentler on the battery, helping to extend its lifespan. Lifespan refers to the period during which a NiMH battery remains usable and performs well.

It is important to always fully charge the battery and avoid storing it empty for extended periods. This helps to maintain the battery’s capacity and significantly prolongs the life of the NiMH battery. Elfa supplies both NiMH batteries and reliable chargers for every application.
