Answer / vishnu

NiCd batteries typically last longer, in terms of number
of charge/discharge cycles, than other rechargeable
batteries, and have faster charge and discharge rates than
lead-acid batteries, with minimal loss of capacity even at
high discharge rates.*The most common alternative to NiCd
batteries are '''[[lead-acid battery|lead-acid
batteries]]'''. Compared to these, NiCd batteries have a
much higher [[energy density]]. This means that, for a
given battery capacity, a NiCd battery is smaller and
lighter than a comparable lead-acid battery. In cases
where size and weight are important considerations (for
example, some transportation applications), NiCd batteries
are preferred over the cheaper lead-acid batteries.
