NiMH batteries perform best when they are conditioned through a discharge/charge cycle. Many chargers do this automatically. On some smart chargers you simply press a button for the conditioning to begin.

Rapid chargers

Charge batteries in a couple of hours. If the batteries and charger are specifically designed for quick charging, battery life should not be prematurely reduced.

Dual charging units

Charge two different sets of batteries simultaneously; eg: NiMH AA and NiHM AAA.

Some chargers have a built-in 100~240V 50/60 Hz power supply. They can be used in other countries with a only an electric plug adapter.
