Maintenance Of Lead Batteries; Maintenance Of Watertight Batteries - BENETEAU OCEANIS 46.1 Owner's Manual

Maintenance
- Keep the batteries clean and dry.
- Regularly check that the terminals and connection cables are clean. If necessary, apply a thin coating of paraffin on the
terminals to prevent corrosion.
- Regularly recharge all of the batteries onboard.
- Keep the batteries charged at all times: this will improve their lifespan.
- Avoid long periods of electrical inactivity (for example when wintering the boat).

Maintenance of lead batteries

- Check the water levels in the batteries annually and top them up with distilled water if they are low.
- Keep all metallic objects away from the batteries.
- Lead batteries contain sulphuric acid: be careful not to knock them over whenever handling them.

Maintenance of watertight batteries

- This type of battery needs no maintenance and does not produce any gas during normal use. No ventilation is needed.
- The optimum temperature for use is between 10°C and 30°C. Lower temperatures will reduce the available capacity.
Higher temperatures will increase the batteries' self-discharge rate.
- Never open watertight batteries.
- Never add acid or distilled water.
- The pressure valves are used to seal the batteries and cannot be opened without being permanently broken.
- If the batteries overheat, a build-up of gas may develop: stay away from the batteries.

- All work carried out on a battery must only
be carried out by someone qualified to do so.
Whenever working on a battery, wear safety
goggles and protective clothing.
- Never smoke or produce a spark near a
battery: this may cause an explosion.
- If any acid accidentally splashes on your
skin or in your eyes, rinse it off immediately and
thoroughly with fresh water. See a doctor
immediately.
- Never touch the battery terminals: you may
suffer an electric shock.
- Refer to the manufacturer's instructions for
use and maintenance.
- It is essential that you disconnect the
battery charger before disconnecting the
battery terminals for maintenance (either by
disconnecting the AC shore power socket or
by cutting the AC circuit breaker of the
battery charger).
