| Totally discharged batteries |
WARNING | Danger of injury! Observe warning notices and safety regulations → Chapter! |
|
| A battery is designated „totally discharged“ when the no-load voltage is less than 11.6 V. |
WARNING | It is not permissible to test or charge batteries whose magic eye shows light yellow. Do not slave/jump start the vehicle! |
| Danger of explosion when checking and charging or slave/jump starting. |
| These batteries must be renewed. |
|
Caution | t
| Totally discharged batteries freeze prematurely. |
| t
| Frozen batteries should no longer be used. |
|
Note | t
| Totally discharged batteries in vehicles before registration must be exchanged prior to delivery. Preliminary damage cannot be excluded. |
| t
| Batteries that have not been used for a long period of time discharge themselves, e.g. those fitted in stored vehicles. |
| t
| In totally discharged batteries, the electrolyte is comprised almost entirely of water because the acid content is so low. |
| t
| Exhaustively discharged batteries sulphate, i.e. 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 mostly 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. |
