WARNING: LEAD ACID BATTERIES
GENERATE GASES WHICH CAN BE EXPLOSIVE.
CHARGE ONLY IN WELL VENTILATED AREAS.
DO NOT DISCONNECT CHARGER DC OUTPUT
TERMINALS FROM BATTERY WHEN CHARGER IS
ON. THE RESULTING ARCING AND BURNING
COULD CAUSE THE BATTERY TO EXPLODE.
KEEP SPARKS, FLAME, AND SMOKING
MATERIALS AWAY FROM BATTERY.
If the charger must be stopped, always
disconnect the AC supply cord from its outlet
before disconnecting the DC output terminals
from the battery.
4. The initial charge current should range between
approximately 20 to 29 amps. If the batteries
have not been discharged, or the AC supply
voltage is lower than 120 volts, the initial charge
rate may be less. If the batteries have been
excessively discharged, or AC supply voltage is
higher than 120 volts, the initial charge rate may
be more.
5. Charge current will gradually taper to
approximately 8 amps depending on the age and
condition of the batteries. Charger turns off
automatically when battery is fully charged.
Charge time varies with battery size and depth of
discharge. Allow 11-15 hours for normal
charging. Severely discharged batteries may
require more time to be properly charged and
equalized.
6. After the charger has turned off, disconnect the
AC supply cord from outlet.
MAINTENANCE INSTRUCTIONS
The battery charger requires minimal maintenance. It
should be kept clean and all connections are to be
tightly secured. In the event of intermittent operation,
examine and tighten, if necessary, all connections.
BE SURE THE CHASSIS IS SECURELY
GROUNDED. If any problems cannot be resolved,
consult a qualified service center.
Observe the following battery maintenance procedures
to obtain good performance and maximum cycle life.
1. Always observe the following personal safety
precautions when working with lead acid
batteries:
a. Someone should be within range of your voice
or close enough to come to your aid when
you work near a battery.
b. Have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing or
eyes.
c. Wear complete eye and clothing protection.
Avoid touching eyes while working near
battery.
d. 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.
e. NEVER smoke or allow a spark or flame in
the vicinity of batteries.
f. 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.
g. 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.
h. NEVER charge a frozen battery.
DANGER: TO REDUCE RISK OF ELECTRIC
SHOCK, ALWAYS DISCONNECT THE AC SUPPLY
CORD FROM ITS OUTLET AND THE DC OUTPUT
CORD FROM THE BATTERY BEFORE
ATTEMPTING ANY MAINTENANCE (CHANGING
FUSES, ETC.) OR CLEANING OF THE BATTERY
OR BATTERY CHARGER.
2. New batteries should be given a full charge before
their first use because it is difficult to know how
long batteries have been stored.
3. Limit use of new batteries for first five cycles.
New batteries are not capable of their rated output
until they have been discharged a number of
times.
4. Do not excessively discharge batteries.
Excessive discharge can cause polarity reversal
of individual cells resulting in complete failure
shortly thereafter. Limited use of new batteries
will minimize the chance of cell reversal.
5. CHECK THE LEVEL OF THE ELECTROLYTE IN
CONVENTIONAL LIQUID ELECTROLYTE LEAD
ACID BATTERIES MONTHLY. MAINTAIN THE
PROPER ELECTROLYTE LEVEL BY ADDING
DISTILLED OR PURIFIED WATER WHEN
NECESSARY. Electrolyte levels lower during
discharge and rise during charge. Therefore, it is
mandatory that water be added to cells ONLY
when they are fully charged; do not overfill. Old
batteries require more frequent additions of water
than new batteries.
