NiMH rechargeable batteries, mainly known as the nickel-metal hydride cell is a secondary electrochemical cell which is similar to the Nickel hydrogen cell. The NiMH batteries use the hydrogen absorbing alloy instead of the cadmium. A NiMH rechargeable battery can have two to three times the capacity of any equivalent size of the nickel-cadmium battery. The self discharge of NiMH batteries is higher.
Purchasing NiMH rechargeable batteries is easy as they are readily available in the retail stores as well as online stores. The common sizes are the AA. For the C and D applications, adapter sleeves are available. These batteries are not very expensive and the voltage and performance is also similar to the alkaline batteries. In fact they can be used as substitutes for the same
