4.2.7.1 Charging the batteries

  • 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.
