1. Performance – Since rechargeable batteries can be recharged many times over, the cumulative total service life exceeds that of primary batteries by a wide margin.
2. Savings – Recharging rechargeable batteries many hundred times is giving the consumer tremendous savings in the long run.
3. Environmentally friendly – Since the cumulative service is so much longer than primary batteries, only a fraction of the solid waste is generated and a solid waste reduction of 90% and more is possible. If the battery contains no toxins, such as rechargeable alkalines, they can be even disposed of in regular landfills. Other rechargeables, which do contain toxins such as NiMH should be recycled. Most stores nowadays do take old rechargeables back.
