The battery should always be charged as full as
possible. Regularly check the state of charge with
the battery acid tester. We recommend to check 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 re-
charged.
DENSITY WITH FULL CHARGE: 1.260 kg/dm

(at
27°C).
ATTENTION:
Never charge the battery on the
boat. The vapors resulting from
charging could cause an explosion!
For a periodical check of the battery, the following items are to be considered:
1
Protect the boat 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).
12.01 ill.1
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.
