| Inspecting electrolyte level |
| Special tools and workshop equipment required |
| t
| Battery filling bottle e.g. - VAS 5045- |
|
|
|
| An external check on the electrolyte level can be made on the on batteries with recognisable “Min.” and “Max.” markings on the battery housing. |
| What to do if there are no “Min.” and “Max.” markings on the battery housing or the electrolyte level cannot be read: |
| –
| Switch off the ignition and all electrical components. |
| –
| This will allow you to see inside the battery and observe the condition of the electrolyte. |
| –
| Always use a torch to illuminate the inside of the battery. |
| –
| Check the condition of the electrolyte visually. |
|
|
|
| –
| The level of the electrolyte is OK when it covers the electrolyte level marking -1-. |
| –
| Distilled water should be added from the battery filling bottle -VAS 5045- up to “Max.” when the electrolyte level is too low. |
| –
| Excess battery acid must be removed by suction if the electrolyte level is too high using a commercially available acid removal device. |
| –
| The battery cells must then be closed off again by just using the original battery plugs once the filling up or removal operations have been completed. |
Diagram not available
Note | Only use original battery plugs of the same type if those from the battery get damaged or lost. The battery plugs must be fitted with an O-ring seal. |
