Generally, primarybatteries have a higher capacity and initial voltage thanrechargeable batteries, and a sloping discharge curve . Mostprimary batteries do not presently require special disposal.

Advantages

High energy density since no design compromises necessary toaccommodate recharging.

Best alternative for low cost, low drain applications such aswatches or hearing aids.

The obvious choice for single use applications such as guidedmissiles and military ordnance.

Low initial cost

Convenient.

Wide availability of standard products

 

Shortcomings

Not suitable for high drain applications due to short life time andthe cost of continuous replacement.

In terms of overall energy efficiency, single use, disposable,primary batteries are an extremely uneconomical energy source sincethey produce only about 2% of the power used in theirmanufacture.

They also produce much more waste than rechargeablebatteries.
