POSSIBLE BATTERY PROBLEMS/SOLUTIONS
1. Weak battery-
be caused by low electrolyte cell levels.
Warm engine compartment temperatures
will deteriorate a battery's life quicker
by evaporating the water from the
electrolyte, thus corroding and weakening the positive
grids inside the battery.
With the house battery low electrolyte levels can be
monitored by periodic inspection and lling as needed
with distilled water. Boaters in higher climate areas with
longer stretches of hot weather will need to check their
batteries more o en.
If installed "maintenance free" engine cranking batteries
require no water. ey do feature a di erent chemistry
that does consume less water. Inside the cells as gases
are released condensation is formed which aids in
maintaining the cell electrolyte level.
incorporate a deeper layer of electrolyte over the plates,
but eventually it can run dry.
2. Dead Battery- Either the battery will not accept a charge,
hold a charge or the charging system is not supplying a
charging current through the battery charging system
and/or engine alternators.
e battery charger output can be checked by monitoring
the lights on the charger front face.
To begin with check the battery post connections for
tightness and corrosion.
With the engines running the displayed voltage of the
port or starboard engine battery and house battery should
be between 12.5 up to 14.6 volts. If less than 12 volts check
for voltage across the battery terminals.
Batteries should be removed from the vessel if necessary
and trickle charged. If readings a er charging are still low
replace the battery.
