Can I use a different brand charger for my eneloop batteries?

We always recommend charging your eneloop rechargeable batteries with an eneloop or Panasonic charger. However, most of the other manufacturers’ chargers will also be able to charge your eneloop batteries, but we cannot guarantee optimal charging and functioning of your eneloop batteries as specifications of these chargers are slightly different depending on manufacturer.
Panasonic/eneloop chargers are specifically built to match the characteristics of their batteries in order to maximise their performance. 

Possible problems which could occur when using another manufacturer’s charger:

1. Repeatedly overcharging the batteries => Leakage and service life shortening
2. Incomplete charging of batteries => Leakage and service life shortening
3. Deterioration of terminals due to abnormal heat => Service life shortening
