Capacity of the charger. Normally, batteries are charged by supplying 10-20% current of their total current capacity. For example, if the capacity of the AA battery is 2000 mAh, the battery will be charged in 5 hours using a charger supplying a current of 400 mA. The same battery will take 10 hours to charge when a 200 mA charger is used.

kiwiroo • Regular Member • Posts: 174. How long should I charge AA rechargeable batteries? I have worked out that if I have 2300 mAh batteries and a charger that delivers 120 mA then I divide 2300 by 120 to give 19.17 hours to charge. But this assumes zero charge when I start charging.
