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 boat's own chargers. In other cases,
remove 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 should be taken at the battery terminals, not the alternator, to achieve the correct result.
4.2.7.2. Charging status
The best method for determining charging status is to measure the specific gravity of the battery acid.
This is done using a hydrometer (acid measurer). Normal specific gravity for a fully charged battery at 20
°C is 1.26-1.28 g/cm³.
The specific gravity varies with temperature. Batteries from different
manufacturers can have a different specific gravity. Ask your dealer for the correct
information.
If the specific gravity varies from cell to cell, the battery is not in good condition, and should be replaced.
For winter storage, the batteries can be left on board only if they are fully charged. A partially discharged
battery can freeze and crack. Always disconnect the cable terminals from the battery to avoid oxidation.
4.2.7.3. Winter storage
For winter storage, the batteries can be left on board only if they are fully charged.
A partially discharged battery can freeze and crack. Always disconnect the cable terminals from the
battery to avoid oxidation. When removing batteries, disconnect the negative pole first and make sure
that there are no flammable or explosive materials or liquids nearby. When putting the batteries back in
place, connect them in reverse order (positive pole first).
4.2.7.4. Cleaning the batteries
The top of the batteries should be cleaned regularly to avoid current leakage between the cells.
If the battery is located in a separate area, it is normally sufficient to clean it in the spring and autumn.
Make sure that the air holes in the cell plugs are open so that gas can be vented.
The terminals and cable terminals must be lubricated to prevent deposits and corrosion.
