A. INTRODUCTION
1. Notes–
• Batteries supply the power for your chair. They contain a
finite amount of energy and have limits on how long they can
store and supply energy.
• You can charge batteries only a certain number of times
before they will fail and no longer hold a charge.
• For answers to questions about batteries, consult your
Authorized Dealer.
2. Use Proper Batteries:
Your chair operates on two 12 volt batteries.
• They should be Group 22 batteries.
• When you buy a replacement, insist on a deep cycle sealed
case type. Do not use a car or boat battery.
3. Breaking In:
• A battery requires "breaking-in" for the first 6 to 12 charges.
It will not accept a full charge for this period.
• It is best to limit the length of your trips until you break the
batteries in and you know the range of your chair.
4. Discharged Batteries:
• Never allow a battery to completely discharge. If you oper-
ate your wheelchair until it has almost stopped, you will
greatly reduce the life of your batteries.
• Never let a battery sit in a discharged condition. Give
unused or stored batteries a full charge once per month.
• Always fully charge the batteries. Avoid charging when it is
not necessary.
Never connect a life support or auxiliary device to a wheelchair
battery. The electrical system may fail, and result in severe injury to
or death of the user.
B. CHARGING YOUR BATTERIES
To avoid the risk of severe injury or death from electrical shock, fire or explosion while charging: Never connect charger to a 240
volt source. The main input voltage is 110 volts. Never make
direct contact across both battery terminals, as an explosion may
occur. A spark may result in an explosion and/or fire resulting in
severe injury or death.
Never touch the charger after it is connected to an electrical out-
let. This may cause electrical shock.
Never connect or disconnect charger from battery while there is
power to the charger.
1. Never use an extension cord. Use of an improper cord
could damage the charger or cause a fire or electrical shock.
2. A battery emits explosive hydrogen gas during charging. To
reduce the risk of fire or explosion:
• Never smoke or allow a spark, flame or high heat near
battery during charging.
• Never allow metal tools or chair parts to make direct
contact across both battery terminals.

ALWAYS:
1. Use the charger that comes with your wheelchair. Read and
follow all instructions and warnings.
2. Make sure room is well ventilated.
3. Turn off all power to your chair.
4. Connect and disconnect battery cables with caution.
NOTE– Always remove and reattach the negative cable (black cable) first.
5. Make sure to allow enough time to fully charge batteries.
NOTE– Batteries should never be left for long periods in the discharged
state. Unused or stored batteries should be given a charge once
per month.
C. BATTERY CHARGER
A battery charger produces a direct current (DC). When applied
to a discharged battery, this reverses the chemical reaction that
led to its discharge.
1. Charge Rate. How fast a battery will charge depends on:
• Its electrical capacity; state of charge; electrolyte tempera-
ture, and; internal condition.
• The DC output of the charger. (The charge rate will vary if
the alternating current (AC) supply is higher or lower than
110 volts).
2. Caution — To Avoid Damage to the Charger:
• Never place the charger on top of a battery during charging.
(Gases from the battery can damage the charger and may
lead to an explosion or fire).
Never place a battery on top of the charger.
•
• Never expose charger to rain or snow.
• Never unplug charger by pulling on the electrical cord. This
will damage the cord.
Never open a charger or attempt to repair it yourself.
•
Return charger to Sunrise or have repairs made only by a
qualified person.
• Keep cord out of the way, where it will not be stepped on,
tripped over, or damaged.
3. Caution — To Avoid Damage to the Battery:
• Make sure you use the correct setting for sealed (gel) bat-
teries (located on the off-board charger).
• Never charge a frozen battery. A fully charged battery will
rarely freeze, but the fluid in a discharged battery can freeze
at 16 degrees Fahrenheit (minus 9 degrees Centigrade). If
you suspect a battery is frozen, thaw it before charging.
