Battery Inspection - Polaris RANGER 500 2018 Service Manual

4. Set battery aside to allow for acid absorption and
stabilization for 30 minutes.
5. Add electrolyte to bring the level back to the upper
level mark on the battery case.
6. Charge battery for 3 - 5 hours at 1/10 of its amp/hour
rating. Examples: 1/10 of 9 amp battery = .9 amp; 1/
10 of 14 amp battery = 1.4 amp; 1/10 of 18 amp
battery = 1.8 amp (recommended charging rates).
7. Check during initial charging to see if electrolyte level
has fallen, and if so, fill with acid to the upper level.
After adding, charge for another hour at the same
rate.
NOTE
This is the last time that electrolyte should be added. If
the level becomes low after this point, add only distilled
water.
8. When charging is complete, install the filling plugs
firmly.
NOTE
Do not apply excessive pressure. Finger tighten only.
Do not over-tighten.
9. Wash off spilled acid with water and baking soda
solution, paying particular attention that any acid is
washed off the terminals. Dry the battery case.

BATTERY INSPECTION

The battery is located under the seat on the drivers side.
1. Inspect the battery case for obvious damage such as
cracks or leaks. Look for discoloration, warping or
raised top, which may indicate the battery has
overheated or been overcharged.

2. Make sure the battery top is clean and dry. A dirty
battery actually discharges across the grime on top
of the case. Use a soft brush and a baking soda
solution. Make sure plugs are finger tight so cleaning
solution doesn't get into the cells and neutralize the
acid.
3. Inspect the battery terminals, screws and cables for
breakage, corrosion or loose connections. Clean the
terminals and cable ends with a wire brush and coat
terminals with Nyogel™.
4. Check the electrolyte level and add distilled water if
necessary.
NOTE
Don't add acid, use distilled water only!
5. Check the vent tube. Make sure it's not kinked,
pinched or otherwise obstructed.
