Six 8-volt deep cycle batteries provide power
for your electric utility vehicle and must be
properly maintained and recharged for maxi-
mum performance and service life.
To maintain your batteries:
1. Clean the tops of the batteries with a so-
lution of baking soda and water, as nec-
essary, to remove corrosion.
CAUTION:
Do not allow cleaning solution to enter
battery cells.
2. Check the fluid level before and after
charging.
G Before charging: only add distilled water if
fluid is below the top of the plates, and then
add just enough to cover plates.
After charging: check that the fluid level is
G
approximately 6.4 mm (0.25 in) to 12.7 mm
(0.5 in) above the plates and 6.4 mm
(0.25 in) to 9.7 mm (0.38 in) below the level
indicator. If the fluid level is low, carefully
add distilled water. Adding distilled water
after charging helps prevent boil over.
