Lead-acid batteries traditionally r

Lead-acid batteries traditionally required a considerable amount of servicing to keep them in good
condition, although this is not now the case with the
advent of sealed and maintenance-free batteries.
However, when a battery is required to withstand a
high rate of charge and discharge on a regular basis,
or is left in a state of disuse for long periods, the
lead-acid cell is not ideal. Alkaline cells on the
other hand require minimum maintenance and are
far better able to withstand electrical abuse such as heavy discharge and over-charging.
