2. The battery should always be charged as full
as possible. Regularly check the state of
charge with the battery acid tester. We
recommend checking the acid density and
acid level periodically every two weeks. If the
density is 0.04 kg/dm³ below the value of full
charge, the battery is to be removed and
recharged.
DENSITY WITH FULL CHARGE:
1.260kg/dm3 (at 27°C).
ATTENTION:
Never charge the battery on the
marine. The vapours resulting
from charging could cause an
explosion!
For a periodical check of the battery, the following items are to be considered:
1. Protect the marine against acid leakage.
2. Clean battery.
3. Check connections and cables.
4. Clean battery contacts. (neg./pos.)
5. Check holding device of battery.
6. Check housing for damages (acid leakage).
7. Check acid density.
8. Disassemble battery for test. In case of less than 3/4 charge, charge it by means of
battery charger, carry out charge test.
9. Check acid level. In case of a bad state of charge or excessive loss of water, check
charge circuit. Clean battery, contacts and terminals with a solution of soda and
water. This neutralizes the battery acid. After cleaning with the solution, rinse the
surface with water by taking care that the solution does not penetrate into the
battery
ATTENTION:
When connecting the battery cables, take special care of correct
polarity. Incorrect polarity destroys electronic components.
