Make sure that the battery compartment is always well ventilated when charging batteries.

Only charge batteries in the boat with the boat's own chargers. In other cases, remove the batteries from the boat.

Remember that the batteries discharge an explosive oxy-hydrogen gas at a voltage of 14.4 volts.

• The voltage of a normal battery in unloaded status is 12.3-12.7 V.

• During charging, the voltage increases and the charging regulator stops the charging process automatically at a preset level.

• The voltage measurement must be taken at the battery terminals, not the alternator, to achieve the correct result.
