Maintenance
- Avoid charging batteries to a voltage greater than 14,6 V.
- 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.
- Continuously maintain the charged batteries: this determines their length of life.
- Avoid long periods of electrical inactivity ( for example when wintering the boat).
Maintenance of lead batteries
- Every year check the water levels in the batteries, and if they are low top them up with
distilled water.
- 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 degree C and 30 degrees 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
destroyed.
- If the batteries overheat, a build-up of gas may develop: Keep 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: risk of an explosion.
- If any acid accidentally splashes on your skin or in your eyes thoroughly
rinse it off immediately with fresh water. See a doctor immediately.
- Never touch the battery terminals: danger of electric shock.
- Refer to the manufacturer's instructions for use and maintenance.
- IT IS IMPERATIVE TO DISCONNECT THE BATTERY CHARGER
BEFORE DISCONNECTING THE BATTERY TERMINALS FOR
MAINTENANCE.
