Technology allows reuse of many items such as
batteries. The latest rechargeable batteries come fully
charged, can hold a charge for up to 2 years when they
are not used, can be recharged in as few as 15 minutes,
and greatly reduce toxic waste when used in place of
discarded conventional batteries. They cost more than
conventional batteries but the extra cost is recovered
quickly, because replacement batteries do not have to
be purchased as often
