X. BATTERIES
INTRODUCTION
1. NOTES -
• Batteries supply the power for your wheelchair.
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 supplier.
2. USE PROPER BATTERIES
• Your power wheelchair operates on two 12 volt
deep cycle, Gel cell batteries.
• They should be Group 24 (or 22NF) size with a
minimum of 50 ampere hour rating. Only deep
cycle sealed case construction batteries should be used
in this device.
• When you buy a replacement, insist on a deep cycle
sealed case type. DO NOT use a car starter 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 power
wheelchair.
4. DISCHARGED BATTERIES
• NEVER allow a battery to completely discharge. If
you operate your power 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
”topping off” with frequent charges.
!
WARNING
NEVER connect a life support or auxiliary device to a power
wheelchair battery. The electrical system may fail, and result in
severe injury or death of user.
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
tem perature, 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 a defective charger to your authorized supplier.
• 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° Fahrenheit (minus 9° Centigrade). If
you suspect a battery is frozen, thaw it before charging.
!
WARNING
Lead acid batteries generate explosive gas while charging.
Carefully read and follow all warnings on batteries in this
Owner's Manual and any labels applied to the product. Not
doing so, could result in fire, explosion, injury and/or death.

PROHIBITED!
NEVER plug two (2) chargers to your wheelchair battery at the
same time. This may lead the electrical system to overheat and
cause a fire resulting in severe injury or death.
