Note
♦
Batteries that have not been used for a long time e.g. vehicles
that have been stored, will self-discharge.
♦
In totally discharged batteries, the electrolyte is comprised al‐
most entirely of water because the acid content is so low.
♦
Totally discharged batteries sulphate, that is, the entire plate
surfaces of the battery harden.
♦
If a battery is recharged shortly after it has totally lost its
charge, the sulphation will dissipate.
♦
If these batteries are not recharged the plates continue to
harden and the ability to recharge is reduced. A reduction in
the battery output is the result.
