Under abnormal use; i.e. leaving the machine without charging for a period of time - we advise that you follow these steps:

If the machine will be standing unused for a period of 30 days or more, then batteries must be fully charged and battery fuses removed using the Maxi fuse-puller provided, prior to this period.

Batteries should be recharged every three months. Charge fully the day before you start using the machine again.
