Battery Maintenance - Regal 53 SC Owner's Manual

BATTERY MAINTENANCE

AGM engine cranking and house batteries as installed on
your vessel are not all together maintenance free. Unlike
regular batteries there are no water fi ll caps to remove
on this style battery but several other items need to be
monitored periodically.
1. Check both positive and negative terminal hardware
for tightness. Loose connections are known to discharge
a battery very quickly.
2. Make sure all terminals are clean. If you fi nd a greenish,
powdery substance, remove the cable connections and
clean both the terminals and the connectors with a wire
brush. If not a battery cleaner tool (available at car parts
stores) or old toothbrush should be used to clean both
the positive and negative terminals. Use a small amount
of baking soda and water. Remove any residue from the
terminal area with a disposable damp cloth.
Install corrosion protection (petroleum jelly or approved
grease) to the posts before reinstalling the terminals.
3. Tighten all battery connectors securely. Check their
tightness by pulling on the connectors. They should not
move from their tightened position. Be sure to reinstall
the positive boot over the battery terminal after tightening
the battery post connection. While using the boat, keep
an eye on the volt meters to monitor the charge level of
each battery bank. Monitor the charge with the engines
turned off (static condition).
The engine alternators recharge the batteries. A fully
charged battery will indicate between 12 and 14 volts on
the voltmeter. Readings below this could indicate a dead
battery cell or a charging system malfunction which should
be checked by a marine professional.
