Volkswagen Golf Service & Repair Manual: 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
| Totally discharged batteries freeze prematurely. |
| Frozen batteries should no longer be used. |
|
 Note
| Totally discharged batteries in vehicles before registration
must be exchanged prior to delivery. Preliminary damage cannot
be excluded. |
| Batteries that have not been used for a long period of time
discharge themselves, e.g. those fitted in stored vehicles. |
| In totally discharged batteries, the electrolyte is
comprised almost entirely of water because the acid content is
so low. |
| Exhaustively discharged batteries sulphate, i.e. the entire
plate surfaces of the battery harden. |
| If a battery is recharged shortly after it has totally lost
its charge, the sulphation will mostly dissipate. |
| 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. |
