Volkswagen Polo Service & Repair Manual: Severely Discharged Batteries
WARNING
| Risk of injury. Follow all Warnings and Safety
Precautions. Refer to
→ Chapter „Warnings and Safety Precautions“. |
|
| For a battery to be indicated as “severely discharged”, the
resting voltage must be less than 11.6 V. |
WARNING
| Batteries that have a light yellow visual indicator
do not have to be tested or charged. Jump starting must
not be used! |
| There is a risk of explosion during testing,
charging or jump starting. |
| These batteries must be replaced. |
|
Caution
| Severely discharged batteries freeze earlier. |
| Batteries that have been frozen must no longer be
used. |
|
 Note
| Severely discharged batteries in vehicles must be replaced
prior to delivery. Pre-existing damage cannot be ruled out. |
| Batteries which have not been used in driving operation for
a long time, for example vehicles in storage, discharge
themselves. |
| For severely discharged batteries, the electrolyte consists
almost completely of water, because the acid portion has been
greatly reduced. |
| Severely discharged batteries become sulfated, meaning all
the battery plate surfaces become hardened. |
| The sulfating process may be largely reversed if a severely
discharged battery is recharged immediately. |
| If the battery is not recharged, the plates will continue to
harden, and the ability to accept a charge will decrease. This
results in reduction of battery performance. |

Check the battery resting voltage. Refer to
