Ni Cd Battery Charger
2 NiO(OH) + Cd + 2 H2O ↔ 2 Ni(OH)2 + Cd(OH)2
Here is a simple and slow charger for better life of small Ni-Cd battery. Charge it for 6-12 hrs using this circuit.

The nickel-cadmium battery is a popular
type of rechargeable battery for portable electronics and toys using the
metals nickel (Ni) and cadmium (Cd) as the active chemicals. They are
sometimes used as a replacement for primary cells,
such as heavy duty or alkaline, being available in many of the same
sizes. It is commonly used in Mobile Phones, Rechargeable Torch, model
airplanes etc.

In our project we have used 2AA size Ni-Cd Battery which is commonly available and can be used in many appliances. This circuit can also recharge common dry cell battery for fewer times at certain level.

Nickel-cadmium cells have potential of
1.2 V. So Nickel-cadmium batteries come in multiple of 1.2 V for eg
2.4V, 3.6V, 4.8V etc but it maintains constant voltage throughout their
service life and about 0.8–1 V when discharged.
The chemical reaction which occurs in a NiCd battery is:2 NiO(OH) + Cd + 2 H2O ↔ 2 Ni(OH)2 + Cd(OH)2
