Totally discharged batteries
  Caution
Danger of injury! Observe warning notices and safety regulations → Chapter!
A battery is designated “totally discharged” when the "no load" voltage is less than 12.2 V.
  Warning
t  Totally discharged batteries freeze prematurely.
t  Frozen batteries should no longer be used.
  Note!
t  Batteries that have not been used for a long time e.g. vehicles that have been stored, self-discharge.
t  In totally discharged batteries, the electrolyte is comprised almost entirely of water because the acid content is so low.
t  Totally discharged batteries sulphate, that means, the entire plate surfaces of the battery harden.
t  If a battery is recharged shortly after it has totally lost its charge, the sulphation will dissipate.
t  If these batteries are not recharged, the plates continue to harden and the ability to recharge is reduced. The result of which is a reduction in the battery output.
–  Check battery "no load" voltage → Chapter.
