On-board batteries

In order to retain functionality, on-board electrical components must also be maintained during winter storage.
The on-board batteries should be disconnected when charged wherever possible, so that no leakage current or silent consumers can discharge the batteries. The cables and pole terminals should be checked too and replaced if necessary. The poles should also be cleaned and lubricated. If possible, the batteries should be stored in a dry place, away from frost. The batteries should be charged at least once a month if possible.
