Service Information: Battery Maintenance - Si54.10-S-0024A

Model 907 

Due to recent events we would like to notify  you again  about the necessity for proper care of batteries in vehicles not being driven. In order to guarantee a maximum service of batteries and to avoid consequential damage, the batteries should be cared for as per the specification.

The batteries (on-board electrical system) have to be checked at the latest after an idle time of 3 weeks with connected batteries, related to the last check or the last charging time.

Check the battery voltage of the on-board electrical system battery as described in the reference document AR54.10-D-1129TS (model 907).

The batteries are to be charged at a battery voltage lower than 12.2 V. If it is necessary to charge the on-board electrical system battery, the additional battery, backup battery and Emergency-P battery (if installed) must also be charged.

In the event of anticipated idle time or laying up of the vehicle for longer than 3 weeks we recommend disconnecting the battery ground lines.

This prevents any battery discharge caused by no-load current consumers.

In order to counteract any self-discharge the batteries must be checked before commissioning the vehicle or charged - at the latest - after every 3 months.

Costs incurred for this cannot be settled through warranty invoicing.
