7.4 Maintaining drive batteries

The drive batteries require minimal maintenance during the boating season, under normal operating conditions.

Electrical hazard

Short circuit may cause serious injury or equipment damage.

Remove all metal jewellery before handling batteries.

Keep tools and metal objects away from energised parts.

Damage to battery caused by deep discharge

The battery state of charge should remain between 40–60 % during storage.

Use a maintenance charger when storing the batteries.

  • Clean the exterior of the batteries as required using cleaning agents recommended by the manufacturer.
    Never use a pressure washer to clean the batteries.
  • Ensure especially that the battery ventilation openings are unobstructed.
  • Keep the battery terminals free of corrosion by regularly applying contact spray.
    Protect unused terminals with protective caps.
For more information on battery maintenance and storage, see a separate equipment manufacturer's manual.
