Operating Instructions

01583G
The charger has an under-voltage protection
mode, which will terminate the charge if battery
voltage does not increase above 18 volts after
10 minutes of charging. This prevents
destroying 12-volt battery systems with this 24-
volt charger. When this occurs, the RED light
will come on steady.
6.
Correct initial charge rate should be between 11
and 13 amps. As the batteries become more
charged, the charge rate decreases. When the
batteries reach approximately 80% of full
charge, the GREEN light will fast blink (eight
times per second), the charge rate will have
decreased as determined by the "BATTERY
TYPE" switch setting and the condition of the
batteries.
Replaceable Electrolyte Deep Cycle Batteries
With healthy batteries, the charging current will
decrease to between 2 to 4 amps and remain
there until the charger turns off. As replaceable
electrolyte deep cycle batteries lose capacity,
the charge rate may no longer decrease to this
reading. The charger will still determine when
the batteries are as charged as they are capable
of being and will turn off. When battery capacity
has decreased to where the charger is no longer
able to taper down to less than 4 amps, or the
batteries will no longer perform as desired they
should be replaced.
Gel Cell and Sealed Deep Cycle Batteries
The charging current will decrease to near zero
and remain there until the charger turns off. Gel
cell deep cycle batteries will still taper to near
zero charge current even as they wear out and
lose capacity and range. As sealed deep cycle
batteries lose capacity and range, the charge
current may no longer decrease to this low a
reading. The charger will still determine when
the batteries are as charged as they are capable
of being and turn off. When the batteries will no
longer perform as desired, they should be
replaced.
7.
Charger is equipped with a thermal breaker,
which automatically turns the charger off if it
overheats. Should charger turn off before the
batteries are fully charged, check to be sure that
all ventilation openings are free from
obstructions. After charger cools down to a safe
temperature, it will automatically restart. If
charger repeatedly overheats, refer to a qualified
service agent.
8.
Charger turns off automatically when batteries
are fully charged as indicated by steady on
GREEN light. Charge time varies with battery
size and depth of discharge. Allow 8 hours for
normal charging. Larger batteries (greater than
150 ampere-hours) or severely discharged
batteries may require up to 16 hours to be
properly charged and equalized. If the charger
operates for 16 hours and is unable to fully
charge the batteries, an internal timer turns the
charger off and begins to fast blink the RED
light.
A maximum voltage shutoff for wet batteries is
an additional safety feature of the charger.
When the battery potential increases above 2.83
volts per cell, the charger cycle is terminated
and the RED light begins to slow blink.
9.
After the charger has turned off, move the
"Power" switch to "OFF", disconnect AC cord
first, then the DC output cord from the
equipment-charging receptacle.
CAUTION: TO AVOID DAMAGE TO THE
CHARGER CORD AND BATTERY CONNECTOR,
DISCONNECT BY GRASPING THE PLUG
HANDLE OR BODY AND PULLING IT STRAIGHT
OUT OF THE BATTERY CONNECTOR. DO NOT
PULL ON THE CHARGER CORD. DO NOT
TWIST, ROCK OR PULL THE PLUG SIDEWAYS.
WARNING: TO PREVENT ARCING OR
BURNING NEAR THE BATTERIES, DO NOT
DISCONNECT THE OUTPUT CORD FROM THE
BATTERIES WHILE THE CHARGER IS
OPERATING. IF THE CHARGE CYCLE MUST BE
INTERRUPTED, FIRST SLIDE THE POWER
SWITCH TO "OFF", THEN DISCONNECT AC
CORD, AND FINALLY THE OUTPUT CORD FROM
THE BATTERIES. KEEP SPARKS, FLAME, AND
SMOKING MATERIALS AWAY FROM
BATTERIES. NO SMOKING.
WARNING: DO NOT LEAVE THE DC
OUTPUT CONNECTOR PLUGGED IN WHILE
UNATTENDED FOR MORE THAN TWO (2) DAYS.
SEVERE OVERCHARGING AND DAMAGE TO
THE BATTERIES MAY RESULT IF THE
CHARGER DOES NOT TURN OFF.
PROPER CARE OF DEEP-CYCLE MOTIVE
POWER BATTERIES
Batteries used on industrial equipment are subjected
to severe deep-cycle duty on a daily basis. For this
reason it is important that only deep-cycle batteries
be used. Although these batteries are designed to
withstand such duty, the following precautions must
be observed to obtain good performance and
maximum cycle life.
CAUTION: ALWAYS WEAR PROTECTIVE
EYE SHIELDS AND CLOTHING WHEN WORKING
WITH BATTERIES. BATTERIES CONTAIN ACID,
WHICH CAN CAUSE BODILY HARM. DO NOT
