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 supplier.
2. Use Proper Batteries:
Your chair operates on two 12 volt batteries.
• They should be Group 24 (or 22NF) size with a minimum of
50 ampere hour rating. Only deep cycle sealed case con-
struction batteries should be used in this device.
• Connecting Type: Post style batteries or flat top batteries
(used when lowest seat-to-floor height is desired).
• When you buy a replacement, insist on a deep cycle sealed
case type. Do not use a car starter battery.
• Group 24 batteries are a minimum requirement for power
seating.
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 "topping off" with
frequent charges.
WARNING
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 user.
B. 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) batter-
ies (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.
Wet cell batteries generate explosive gas while charg-
ing. Completely read and follow all warnings about the
batteries in this user instruction manual and any labels
applied to the product. Failure to do so could result in
fire, explosion, injury and/or death.
Sunrise does not recommend wet cell batteries.
C. CONNECTING BATTERIES IN BATTERY

COMPARTMENT

1. Batteries weigh up to 55 lbs. (25 kg). Take care to avoid
injury when lifting.
2. Keep batteries upright. Take care not to spill acid (wet
cell batteries).
3. Always wear rubber gloves and safety glasses when you
handle batteries.
4. Before working around batteries, remove all metal
personal effects, such as necklaces, rings, watches, pins
and other metal jewelry that might contact battery
terminal and cause a short.
1. Lift batteries into battery compartment.
Batteries weigh up to 55 pounds (25 kg). Lifting batter-
ies may cause back strain. If you fail to heed these
warnings severe injury may occur to you.
2. Connect and disconnect battery cables with caution. Connect
the red lead to the positive terminal and the black lead to the
negative terminal. Do this for each battery.
3. Tighten all terminal fasteners using two 1/2" box end
wrenches to 60 in-lbs (6.8 N.m).
4. Place the battery compartment lid on power base.
Never make direct contact across both battery termi-
nals, as an explosion may occur. A spark may result in an
explosion and/or fire resulting in severe injury or death.
