Answer:
Nickel Metal Hydride (NiMH) rechargeable batteries are different for a number of reasons. NiMH rechargeable batteries are far superior to rechargeable alkaline and NiCad chemistries because of the amount of capacity, lighter weight, recharge cycles, no memory effect, not to mention the enormous cost savings over time.
Rechargeable alkaline batteries can only be charged up to 50 times. What’s more, rechargeable alkaline batteries must be completely discharged before they can be charged again.
Because of its chemistry, rechargeable nickel cadmium (NiCad) has a limitation to the amount of capacity it can hold. In addition, NiCad batteries are highly susceptible to ‘memory effect’. Also NiCad batteries are considered toxic to the enviromnment, and must be disposed of properly.
