| Measuring no-load voltage |
| Special tools and workshop equipment required |
| t
| Hand multimeter (e.g. -V.A.G 1526A -) |
Note | t
| The battery must not be drained by any electrical equipment for at least 2 hours before the measurement is taken. |
| t
| If the battery was charged, perform measurement only 2 hours after the performed charging. |
| Follow the procedure described below for measuring the battery voltage in the no-load state: |
| –
| Use the handheld multimeter to measure the battery voltage. |
| The battery no-load voltage must not fall below 12.5 V. |
| If the handheld multimeter indicates 12.5 V or more, the battery voltage is O.K. |
| If the handheld multimeter a battery voltage of less than 12.5 V: |
| After charging wait at least 2 hours during which the battery with electrical components must not be subjected to any load or charge: |
| –
| Use the handheld multimeter to measure the battery voltage. |
| The battery no-load voltage must not fall below 12.5 V. |
| –
| If the no-load voltage is N.O.K., replace battery. |
