OBAE, OBAEXU, ON BOARD Battery Chargers
INTRODUCTION:
The OBAE line of chargers are designed for the permanent installation on battery powered
vehicles and equipment. They are an electronically controlled two stage charger. The first stage
brings the batteries to the gassing threshold where a three hour timer starts. The batteries are then
gassed for three hours. After three hours, the charger drops into a low float mode where the
charge is maintained in the batteries indefinitely. Finish current is below 1 amp.
SOME APPLICATIONS:
Golf cars, pallet trucks, personnel carriers, scissor lifts, floor scrubbers, stand-by power
applications, robotics.
IMPORTANT: DO NOT USE THIS CHARGER UNTIL YOU HAVE READ ALL THE
INSTRUCTIONS.
INITIAL INSTALLATION:
Before making AC connections, refer to the AC requirements labeled on the charger. If your
charger is not equipped with an AC plug ( a 220 volt model) have a qualified electrician install
one.
CAUTION: To reduce the risk of fire, use this charger only on circuits provided with
a maximum of 20 ampere branch circuit protection (circuit breaker or fuse),
In accordance with the National Electric Code, ANSI/NFPA 70, and all local
codes and ordinances.
GROUNDING INSTRUCTIONS:
This battery charger must be grounded to reduce the risk of electric shock. If the charger is
equipped with a grounding type plug, it must be plugged into a nominal 115 volt, 60 Hertz circuit.
If the charger is supplied with no plug, have a qualified service person install one.
WARNING: Improper connection of the equipment grounding conductor can result in a
risk of an electric shock. DO NOT USE THIS CHARGER ON A TWO
POLE UNGROUNDED OUTLET OR ATTEMPT TO BREAK OFF THE
GROUND PRONG FOR USE ON A RECEPTACLE OR EXTENSION
CORD NOT HAVING A GROUND.
The use of an extension cord with this charger should be avoided. The use of an improper
extension cord result in a risk of a fire or electric shock. If an extension cord must be used, make
sure it is in good condition. Use a three conductor cord no smaller than 14 AWG. And keep it as
short as possible. Locate all cords so that they will not be stepped on, tripped over, or otherwise
subjected to damage or stress.
Do not operate this charger if it shows any signs of physical damage.

Parallel
Series
When batteries are connected
in parallel, the battery amp hour
rating is additive, and the voltage
remains the same. Example:
Two 180 amp hour, 12 volt batteries
would equal 12 volts, and 360
amp hours capacity.
When batteries are connected in
series, the voltage is additive, and
the amp hour rating remains the
same. Example: Two 180 amp
hour, 12 volt batteries would equal
24 volts, and 180 amp hours of
capacity.

PROPER CARE AND USE OF BATTERIES:
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. Do not wear jewelry when working around
batteries. Arcing can cause sever burns.
New batteries will not deliver their full performance until after several cycles.
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 post and frame.
Maintain the proper electrolyte level by adding water when necessary. Never allow the
electrolyte level to fall below the top of the battery plates. Electrolyte levels fall during
discharge and rise during charging. Therefore, to prevent the overflow of electrolyte when
charging, add water ONLY AFTER the batteries have been fully charged DO NOT
OVERFILL. Old batteries require more frequent additions of water than do new batteries.
Do not over discharge the batteries. Excessive discharge can cause polarity reversal of
individual cells resulting in complete battery failure.
Provide adequate ventilation for the batteries and charger. Do not obstruct the flow of cooling air
around the charger. Provide at least 1" of space around charger. Do not allow clothing, blankets or
other material to cover the charger. Mount the charger firmly in place.
WARNING: Chargers can ignite flammable materials and vapors. Do not use near fuels,
grain, dust, solvents, or other flammable s.
CAUTION: Before connecting the charger to the batteries, make sure the battery pack is of
the same voltage rating of the charger. If you are unsure, count the number of
cells on the battery pack and multiply by two. This figure should be the same
as the DC voltage rating of the charger. ( see ratings label on charger ).

WARNING: Make sure the DC output leads, terminals or connector are all in good
working condition.
DO NOT USE THIS CHARGER IF:
The DC output connector, (if equipped ) is loose or does not make good contact; Is cracked or
broken; The leads are cut or have exposed wires; The DC output leads or connector feel hot when
used.
Using this charger with any of the above symptoms could result in a fire, property damage, or
personal injury. Have a qualified service person make the necessary repairs. Repairs should not
be made by people who are not qualified.
NORMAL OPERATION
1.) When connecting charge leads directly to the battery, apply grease to the terminals to inhibit
corrosion.
2.) Plug the charger into AC power having the same ratings as that of the charger.
3). The LED on the charger will light, indicating charge current is flowing.
4). The OBAE chargers are equipped with a electronic timer. At the battery gassing threshold,
(2.3 volts per cell) the timer will activate and run for three hours. During this period, the
batteries are in a gassing or equalizing mode. (2.5 - 2.6 volts per cell max.) After three
hours the charger will drop the batteries into a low float mode, indicated by a blinking LED.
(2.26 volts per cell) Current in the float mode is less than 1 amp.
The charger may be left on indefinitely, but water level should be checked periodically on
wet batteries.
5). To discontinue charging, unplug the AC power cord. Plugging the AC power back in will
cause the charger to repeat the cycle.
WARNING: Do not disconnect the DC output leads or unplug the connector from the
batteries when the charger is on. The resulting arcing could cause the
batteries to explode. If the charger must be stopped unplug the AC power.
WARNING: Failure to unplug AC power before moving or driving equipment will result
in damage to cords, plugs and receptacles.
TROUBLE SHOOTING:
CAUTION: DO NOT DISASSEMBLE THE CHARGER. Incorrect assembly may result
in a risk of electric shock or fire. Contact factory.
DANGER: To reduce the risk of electric shock, always disconnect both the AC power
supply cord and the output leads or connector before attempting any
maintenance cleaning.

1). LED DOES NOT COME ON WHEN POWER IS APPLIED
Be sure you are plugged into a live circuit. Check the AC cord for breaks in the cord or plug.
Check the DC leads for breaks. Check the DC connections to the battery, clean if heavily
corroded.
Place a volt meter across the battery terminals where the charger is connected. Apply AC
power. If the voltage rises on the battery, the charger is working and the LED is defective.
NOTE: LED s do not burn out, but it has probably received a sharp blow causing physical
damage. No harm will come from operating the charger without a working LED.
2). LED NEVER BLINKS
This could be one of two problems. The batteries never reached timer trip voltage and the
charger was unable to gas and fall into the float mode. This indicates several shorted cells.
overheating and excessive water usage are symptoms of this condition. Performance will
also be greatly diminished. Replace defective battery.
The charger did reach the float mode, but the battery has one or more shorted cells inhibiting
the charger current to fall low enough to start the LED blinking. Replace defective battery.
3). AC LINE FUSE OR CIRCUIT BREAKER BLOWS
Either the circuit breaker or fuse is weak, or the charger is shorted internally.
4). NO POWER IS PRESENT ACROSS THE DC LEADS WHEN A VOLT METER IS
CONNECTED
Good. The charger will not turn on until leads are connected, correct polarity to the battery.
5). BATTERIES DON T RECEIVE FULL CHARGE
The battery you are charging may be to large for the charger, or if you have the charger
plugged into a long extension cord that is too small, a voltage drop will cause a decrease in
charger output, extending charge times.
