The scheme shows a simple charger for Ni. MH batteries. It`s consist of the transformer, bridge rectifier, electrolytic capacitor, a smoothing circuit and LED - charge indicator

It should be noted that in modern chargers use pulse stabilized power supply. Switching power supply in the same dimensions have a power in 10 times higher, and the weight in 10 times smaller than conventional transformers.

Now chargers are based on microprocessors and are smart digital device with a large number of settings. In the settings you can set the charging current, and other parameters of charging. Also, the device by itself detects the battery in the base station.

Modern chargers are able to charge different types of batteries from lead-acid to lithium-polymer batteries. They support a wide range of capacities and voltage battery. In the photo presented i. MAX B 6 the leader among hobby chargers.
