Battery Problems/Solutions
1. Weak battery- This battery problem
can be caused by low electrolyte cell
levels.
W a r m , b i l g e c o m p a r t m e n t
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.
Low electrolyte levels can be monitored by periodic
inspection and filling as needed with distilled water.
Boaters in higher climate areas with longer stretches
of hot weather will need to check their batteries
more often.
"Maintenance free" engine cranking batteries
require no water and cells are not accessible.
They do feature a different chemistry that does
consume less water. Inside the cells as gases are
released condensation is formed which aids in
maintaining the cell electrolyte level. These batteries
incorporate a deeper layer of electrolyte over the
plates, but eventually it can run dry. On the 31 series
engine cranking batteries keep all terminals clean,
connections tight and your electrical system in top
shape to extend battery life.
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.
The 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 engine running the displayed voltage of the
battery should be between 12.5 up to 14.6 volts.
If less than 12 volts check for voltage across the
battery terminals.
If less than 12 volts check with a hydrometer to
locate faulty cells.
Maintenance free batteries they can be removed
from the vessel if necessary and trickle charged.
If readings after charging are still low replace the
battery.
