have someone close by should an emergency arise.
b) Always have soap and water on-hand in case of accidental exposure
to battery acid on skin, clothes or eyes.
6 | ®
c) Always wear proper safety equipment when working with lead-acid
batteries including protective safety goggles and gloves.
d) If your skin or clothing comes into contact with battery acid,
immediately wash with soap and water. If battery acid comes into
contact with eyes, immediately flush eyes with cold running water for
at least 10 minutes and seek medical assistance as soon as possible.
e) DO NOT SMOKE AROUND BATTERIES WHILE CHARGING. FAILING TO
DO SO COULD IGNITE AN EXPLOSION
f) Avoid anything that may cause a spark near the batteries while
charging.
g) Avoid wearing jewelry such as rings, bracelets, necklaces or watches
when working with lead-acid batteries.
h) Always keep your cellphone as far away from your batteries while
charging as possible. Cellphones can create sparks which can lead to an
explosion.
j) Only charge lead-acid batteries specified by this manual. Never
charge dry-cell batteries as they may burst
k) NEVER CHARGE FROZEN BATTERIES AS THEY MAY EXPLODE CAUSING
DAMAGE, BODILY INJURY OR DEATH
11.PREPARING TO CHARGE
a) Confirm golf cart batteries are flooded/wet cell. The battery charger
cannot charge sealed and AGM type batteries
b) Ensure all batteries are at the proper water levels. Be careful not to
overfill batteries. Always adhere to the battery manufacturer’s
maintenance and operation instructions.
7 | ®
c) Follow the battery manufacturer’s recommended rates of charge and
recharging procedures.
13.CHARGING LOCATION
a) Only use the charger in well ventilated areas. Using the charger in a
confined space will decrease the efficiency and lifespan of the charger.
