The battery life of a rechargeable battery is affected by how hard you make it work when recharging. Aggressive battery charging will shorten the number of charge-discharge cycles you get from your batteries before you start to see a decline in capacity and/or performance.
The recommended maximum charge rate from most battery manufacturers is 1C, or 1 x the Capacity of the battery. For a 2700mAh AA battery, the maximum charge rate is 2700mA. A 15 minute rapid charger is very aggressive, charging at 4C. Absorbing the energy so fast will cause the batteries to become quite hot, and will shorten the life of the batteries. Any charger that takes 1 hour or longer to charge batteries will meet the 1C recommendations.
For example, The MH-C801D has a standard charge rate of 2000mA for AA batteries, so it is below the maximum recommended charge rate for our 2100mAh IMEDION AA batteries and our 2700mAh Powerex AA’s. The MH-C801D also has a SOFT CHARGE feature, which halves the charge rate to 1000mA, making the charging process even easier on the batteries. I would recommend using the SOFT charge feature whenever you have the time to charge your batteries at 1000mA, and feel free to use the 2000mA charge rate when you need batteries charged fast.
