INTRODUCTION
The Dual-Mode wheelchair battery charger is
designed to recharge deep-cycle batteries of
conventional replaceable electrolyte or gel cell and
"maintenance-free" sealed design. The different
charge characteristics required by these different
types of battery designs are selected by sliding the
1
00949U
BATTERY TYPE selector switch to the correct
setting. A patented electronic circuit turns the
charger ON and OFF automatically.
CAUTION: KEEP DRY; DO NOT EXPOSE TO
RAIN OR SPRAY.
FOR STORAGE, KEEP
CHARGER IN A BUILDING. REPLACE WORN,
CUT OR DAMAGED ELECTRICAL CORDS AND
PLUGS IMMEDIATELY.
Batteries used on wheelchairs are subjected to
severe deep-cycle duty on a daily basis. For this
reason, it is important that only Deep-Cycle batteries
be used.

BATTERIES. "BATTERY TYPE" SWITCH MUST
BE SET TO THE PROPER TYPE OF BATTERY.
BATTERIES IMPROPERLY MATCHED WITH
CHARGER MAY BURST, CAUSING PERSONAL
INJURY AND DAMAGE TO BATTERIES OR
CHARGER.
This battery charger must be grounded to reduce
the risk of electric shock. It is equipped with an
electric cord having an equipment-grounding
conductor and a grounding-type plug. The plug
must be plugged into an appropriate outlet,
supplied with a ground fault interrupter, that is
properly installed and grounded in accordance with
the National Electrical Code and all local codes and
ordinances.
DANGER:
IMPROPER CONNECTION OF
THE EQUIPMENT-GROUNDING CONDUCTOR
CAN RESULT IN A RISK OF AN ELECTRIC
SHOCK.
DO NOT REMOVE GROUNDING
PRONG FROM PLUG.
INITIAL INSTALLATION
This battery charger is equipped with a grounding
plus as illustrated in Figure A, for use on a nominal
120 volt, 60 Hertz circuit. A temporary adapter, as
illustrated in Figures B and C may be used until a
properly grounded outlet can be installed by a
qualified electrician. The GREEN-colored rigid ear
extending from the adapter must be connected to a
permanent ground such as a properly grounded
outlet box.
Circuit breaker or fuse protection in the 120 volt AC
outlet into which the charger is to be plugged should
allow 5 amps per charger. Do not overload the
electric outlet. The use of an extension cord with
the charger should be avoided. The use of an
improper extension cord could result in a risk of an
electric shock. If an extension cord must be used,
use a three-conductor, No. 16 AWG (or larger) cord
with ground, properly wired, in good electrical
condition, and keep it as short as possible. Make
sure that the pins of the plug on the extension cord
are the same number, size, and shape as that of the
plug on the battery charger. 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 with a damaged cord or plug.
Do not operate this charger if it has received a sharp
blow, was dropped or otherwise damaged in any
manner; refer to a qualified service agent.
DANGER: BEFORE USING THE ADAPTER
AS ILLUSTRATED, BE CERTAIN THAT THE
CENTER SCREW OF THE OUTLET PLATE IS
GROUNDED.
GROUNDING METHODS
Provide adequate ventilation for both batteries and
charger. The convection cooled design requires an
unobstructed flow of cooling air for proper operation.
Keep all charger ventilation openings at least two
inches (2") (5.08cm) away from walls and other
objects. Do not allow clothing, blankets, or other
material to cover charger. DO NOT place under
bed.
NOTE: Use of adapter shown in Figures B and C is
NOT permitted in Canada.
WARNING:
CHARGERS CAN IGNITE
FLAMMABLE MATERIALS AND VAPORS. DO
NOT USE NEAR FUELS, GRAIN DUST,

batteries are fully charged, check to be sure 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.
WARNING: ALWAYS SHIELD EYES WHEN
WORKING NEAR BATTERIES. DO NOT PUT
WRENCHES OR OTHER METAL OBJECTS
ACROSS BATTERY TERMINAL OR BATTERY
TOP.
ARCING OR EXPLOSION OF THE
BATTERY CAN RESULT!
5. Charger turns off automatically when batteries
are fully charged. Charge time varies with
battery size and depth of discharge. Allow 8
hours for normal charging. Larger batteries
(greater than 85 ampere-hours) or severely
discharged batteries may require up to 14 hours
to be properly charged and equalized. If the
charger operates for 14 hours and is unable to
fully charge the batteries, an internal timer turns
the charger off, extinguishes the YELLOW
charge light, and turns the RED fault light on.
Charger will turn ON one to three (1-3) seconds
after completion of the last of the above actions,
and the charger ammeter will indicate initial
charge current.
If the YELLOW light does not illuminate and the
POWER switch is in the "ON" position, the AC
outlet is not live or an open circuit exists in the
wheelchair’s internal circuitry. Test for a live AC
outlet by connecting a suitable household
appliance to the specific outlet. If the outlet
tests live, then the fault is in the wheelchair
wiring. Take the wheelchair to your dealer to
have the fault corrected (see Troubleshooting).
6. After the charger has turned off, move the
POWER switch to "OFF", disconnect AC cord
first, then the DC output cord from the
wheelchair charging receptacle.
4. Monitor ammeter for correct initial charge rate.
Correct initial charge rate should be between 7
and 9 amps.
As the battery reaches
approximately 70% of full charge, the charge
rate gradually decreases to a reading
determined by the "BATTERY TYPE" switch
setting and the condition of the batteries.
CAUTION: TO AVOID DAMAGE TO THE
CHARGER CORD AND BATTERY CONNECTOR,
DISCONNECT BY GRASPING THE PLUG
HANDLE 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.
Replaceable Electrolyte Deep Cycle Batteries
With healthy batteries, the charging current will
decrease to between 2 and 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.
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.
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.
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 MOTIVE POWER BATTERIES
Batteries used on wheelchairs 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

BATTERIES
CONTAIN ACID WHICH CAN CAUSE BODILY
HARM. DO NOT PLACE WRENCHES OR OTHER
METAL OBJECTS ACROSS THE BATTERY
TERMINALS OR BATTERY TOP. ARCING OR
EXPLOSION OF THE BATTERY MAY RESULT.
SOMEONE SHOULD BE WITHIN THE RANGE OF
YOUR VOICE OR CLOSE ENOUGH TO COME TO
YOUR AID WHEN YOU WORK NEAR A LEADACID BATTERY. HAVE PLENTY OF FRESH
WATER AND SOAP NEARBY IN CASE BATTERY
ACID CONTACTS SKIN, CLOTHING, OR EYES.
2. Have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing, or
eyes.
3. Wear complete eye protection 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 clod
water for at least 10 minutes and get medical
attention immediately.
5. NEVER smoke or allow a spark or flame in
vicinity of batteries.
WARNING: RISK OF EXPLOSIVE GASES.
WORKING IN VICINITY OF A LEAD-ACID
BATTERY IS DANGEROUS.
BATTERIES
GENERATE
EXPLOSIVE
GASES
DURING
NORMAL BATTERY OPERATION. FOR THIS
REASON, IT IS OF UTMOST IMPORTANCE THAT
EACH TIME BEFORE USING YOUR CHARGER,
YOU READ THIS MANUAL AND FOLLOW THE
INSTRUCTIONS EXACTLY.
6. Be extra cautious to reduce a risk of dropping a
metal tool onto battery. It might spark or shortcircuit battery or other electrical part that may
cause explosion.
1. 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.
8. NEVER charge a frozen battery.
2. Limit use of new batteries for first 5 cycles. New
batteries are not capable of their rated output
until they have been discharged and charged a
number of times.
DUAL MODE WHEELCHAIR CHARGER
TROUBLESHOOTING
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 high enough to weld a
ring or the like to metal, causing a severe burn.
CAUTION: DO NOT DISASSEMBLE THE
CHARGER. TAKE IT TO A QUALIFIED SERVICE
AGENT WHEN SERVICE OR REPAIR IS
REQUIRED. INCORRECT REASSEMBLY MAY
RESULT IN A RISK OF ELECTRIC SHOCK OR
FIRE. THE FOLLOWING PROCEDURES ARE
INTENDED ONLY TO DETERMINE IF A
MALFUNCTION MAY EXIST IN THE CHARGER,
OR IN THE WHEELCHAIR AND BATTERIES.
3. 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 risk of cell reversals.
4. 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 fall during discharge and rise during
charge. Therefore, it is mandatory that water be
added to the cells ONLY when they are fully
charged; do not overfill. Old batteries require
more frequent additions of water than new
batteries.
DANGER: TO REDUCE RISK OF ELECTRIC
SHOCK, ALWAYS DISCONNECT BOTH THE
POWER SUPPLY CORD AND THE OUTPUT
CORD
BEFORE
ATTEMPTING
ANY
MAINTENANCE OR CLEANING.
CAUTION:
DO NOT OPERATE THE
CHARGER IF IT IS DAMAGED OR APPEARS TO
BE MALFUNCTIONING. PERSONAL INJURY OR
DAMAGE

d. Battery connections in wheelchair are wrong
(reverse polarity).
b. Use of the wheelchair before the batteries
have been fully charged and the charger
turns off shortens battery life and hastens
the onset of reduced daily range. Battery
capacity lost in this manner is permanent
and is not recovered with additional charge
cycles.
e. One or both batteries no longer serviceable
(voltage below 13 volts for 24 volt system).
2. If the charger turns off before the batteries are
fully charged, it indicates one of the following:
a. Charger internal thermostat turned the
charger off due to overheating because
charger ventilation openings are blocked.
After the charger has cooled down to a safe
temperature, it will automatically restart. If
the charger repeatedly overheats, it may be
malfunctioning.
