Low Maintenance Battery Charging
Procedure
1. Remove the battery from the ATV to prevent damage
from leaking or spilled acid during charging.
2. Charge the battery with a variable rate charging
o
utput. Charge as needed to raise the specific gravity
to 1.270 or greater.
3. Install battery in vehicle with posit
ive terminal toward
the front. Coat threads of battery bolt with a corrosion
resistant Nyogel™ Grease (PN 2871329).
4. Route cables so they are tucked away in front and
b
ehind battery.
5. Connect battery cables.
6. After connecting the battery cables, install the cover
o
n the battery and attach the hold down strap.
Low Maintenance Battery Off-season
Storage
Battery voltage should be checked with a digital
multitester. Readings of 12.8 volts or less require further
battery testing and charging. See charts and Load Test.
• Remove the battery from the machine and wash
the case an
d battery tray with a mild solution of
baking soda and water. Rinse with lots of fresh
water after cleaning.
• Using a wire brush or knife, remove any corrosion
from
the cables and terminals.
• Make sure that the electrolyte is at the proper
level.
• Charge at a rate no greater than 1/10 of the
ba
ttery's amp/hr capacity until the electrolyte's
specific gravity reaches 1.270 or greater.
• Store the battery either in the machine with the
cable
s disconnected, or store in a cool place.
NOTE: Stored batteries lose their charge at the rate
o
f 1% per day. Recharge to full capacity every 30 to
60 days during a non-use period. If the battery is
stored during the winter months, electrolyte will
freeze at higher temperatures as the battery
discharges. The chart below indicates freezing
points by specific gravity.
To avoid the possibility of sparks and explosion,
connect positive (red) cable first and negative
(black) cable last.
