CAUTION: ALWAYS WEAR PROTECTIVE
EYE SHIELDS AND CLOTHING WHEN WORKING
WITH BATTERIES. BATTERIES CONTAIN ACIDS
WHICH CAN CAUSE BODILY HARM. DO NOT
PUT WRENCHES OR OTHER METAL OBJECTS
ACROSS THE BATTERY TERMINAL OR
BATTERY TOP. ARCING OR EXPLOSION OF
THE BATTERY CAN RESULT.
1. When installing new batteries, be sure the
polarity of each battery and overall battery pack
is correct. Battery and/or charger damage can
result.
2. New batteries should be given a full charge
before their first use because it is difficult to
know how long the batteries have been stored.
3. Limit the use of new batteries for the first 20
cycles. New batteries and older batteries that
have been in storage are not capable of their
rated output until they have been discharged
and charged a number of times.
4. DO NOT EXCESSIVELY DISCHARGE THE
BATTERIES. Excessive discharge can cause
polarity reversal of individual cells resulting in
complete failure shortly thereafter. Heavily
discharging (over 60%) new batteries before
they have been broken in (approximately 20
cycles) can cause permanent cell damage,
resulting in reduced energy capacity and
shortened life.
5. Maintain the proper electrolyte level of flooded
electrolyte batteries by adding water when
necessary. Distilled or deionized water is free of
contaminants and preferred for this use. Never
allow the electrolyte level to fall below the top of
the battery plates. Electrolyte levels lower
during discharge and rise during charge.
Therefore, to prevent the overflow of electrolyte
when charging, it is mandatory that water be
added to cells AFTER they have been fully
charged; do not overfill. Old batteries require
more frequent additions of water than do new
batteries.
6. Hard crystalline sulfates form when batteries in
storage are not maintained in a charged active
state. Internal self-discharge can bring about
the start of this condition in as little as three days
in warm temperatures. Batteries allowed to sit
unmaintained in storage will self-discharge,
sulfate to various degrees and lose capacity.
Repeated charging without using the batteries
between charges can recover some of the lost
power, range, and life, but some permanent loss
should be expected.
7. When the temperature falls below 65
°F, the
batteries should be placed on charge as soon
after use as possible. Cold batteries require
more time to fully recharge.
8. The tops of the batteries and battery hold-downs
must be kept clean and dry at all times to
prevent excessive self-discharge and flow of
current between the battery posts and frame.
Electrolyte spilled on the batteries never dries or
evaporates.
9. All connections to batteries that are bolted must
be maintained clean and bright. Due to heating
and discharge rates, bolted connections loosen
over time. Re-tighten the connections twice
yearly to the manufacturer's specified torque.
10. Follow all operating instructions, cautions, and
warnings as specified in this manual, on the
charger, and in your vehicle owner’s manual.
PERSONAL PRECAUTIONS
1. Someone should be within range of your voice
or close enough to come to your aid when you
work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing, or
eyes.
3. Wear complete eye and clothing protection.
Avoid touching eyes while working near battery.
4. If battery acid contacts skin or clothing, wash
immediately with soap and water. If acid enters
eye, immediately flood eye with running cold
water for at least 10 minutes and get medical
attention immediately.
5. NEVER smoke or allow a spark or flame in
vicinity of battery.
6. Be extra cautious to reduce risk of dropping a
metal tool onto battery. It might spark or short-
circuit battery or other electrical part that may
cause explosion.
7. Remove personal metal items such as rings,
bracelets, necklaces, and watches when
working with a lead-acid battery. A lead-acid
battery can produce a short-circuit current high
enough to weld a ring or the like to metal,
causing a severe burn.
8. NEVER charge a frozen battery.
