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. |
