BATTERY MAINTENANCE
Maintenance Free Type
The Group 31 “maintenance free” engine cranking
batteries 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 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 to the posts before reinstalling
the terminals. Refer to the illustration.
3. After all preventative maintenance is completed
slide the red boot back over the positive terminal. Th
is
will prevent any object from arcing across the positive
terminal to ground possibly causing a fi re.
House- (Fill Cap Type)
Th e single house “deep cycle” house battery located in the
blue and white battery box needs periodic maintenance
for optimum performance. Remove the cover by turning
the 2 white knobs in a counterclockwise direction. Since
this type of battery features fi ll caps each cell’s water level
can be monitored and distilled water can be added as
needed. Follow these maintenance steps for the house
battery.
1. Th e fi rst item to be checked is the open-cell voltage. Use
a dedicated battery tester or a voltmeter. With the battery
fully charged with no circuits energized the voltage across
the terminals should be 12.5 to 12.6 volts.
