Remember that a partially charged battery requires less time for recharging.

When choosing a charger for AA rechargeable batteries, you will frequently encounter the terms fast charger and rapid charger. As mentioned previously, the capacity of the battery dictates its charging time. A charger that is capable of charging a standard nickel cadmium 180 mAH battery in one hour can take as long as eight hours to recharge a NiMH 1500 battery that has a higher capacity.
