above plates. Fill with distilled water only. After dis-
tilled water has been added, wait at least a half hour to
measure solution density (specific gravity). The specific
gravity should be between 1.258–1.265 or the electrolyte
level within “MIN” and “MAX” marks.
• When fast charging, remove the battery caps so pres-
sure does not accumulate.
• Always make sure the battery charger is OFF before
connecting or disconnecting the cable clamps.
• To avoid short circuits and damage to yourself or the
vehicle, never place metal tools or jumper cables on the
battery or nearby. Metal that accidentally comes in con-
tact with the positive battery terminal or any other metal
on the vehicle (that is in contact with the positive termi-
nal), could cause a short circuit or an explosion.
Charging Reminders
• Use protective eyewear.
• Keep all batteries away from children.
• Never reverse battery poles.
• Never attempt to place the vehicle in motion, or run the
engine with batteries disconnected.
• Keep the battery clean and dry.
• Look for any signs of damage.
WARNING! Never use a metallic funnel to add
distilled water. It could come in contact with a
terminal, creating a short circuit, resulting in
severe personal injury or damage to your vehi-
cle.
WARNING! Always shield your eyes and avoid
leaning over the battery whenever possible.
Electrolyte in batteries could splash up into your
eyes causing severe burns and/or serious per-
sonal injury.
• Battery terminals should not be coated with improper
grease. Use petroleum jelly or commercially available,
noncorrosive, nonconductive terminal coatings.
• Battery acid that may spill during charging should be
washed off with a solution of warm water and baking
soda to neutralize the acid. If you accidentally get acid in
your eyes or on your skin, immediately rinse with cold
water for several minutes and call a doctor.
• Do not charge a frozen battery; allow it to thaw out first.
And always allow the battery to thaw gradually—do not
apply direct heat. Gas trapped in the ice may cause an
explosion.
