A.INTRODUCTION
Notes-
1.
• Batteries supply the power for your chair. They contain a
definite 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 sup-
plier.
2. Use Proper Batteries:
Your chair operates on two 12 volt batteries.
• They should be Group 22NFsize with a minimum of 50
ampere hour rating. Only deep cycle sealed case construction
batteries should be used in this device.
• Connecting configuration. They should have a post and
clamp style connection.
• 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 chair.
4. Discharged Batteries:
• Never allow a battery to completely discharge. If you
operate 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 tem-
pera ture, and; internal condition.
• The DC output of the charger. (The charge rate will vary
ifthe 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
Quickie X2 Owner's Manual
• 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.
Lead acid batteries generate explosive gas while charging.
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.
C. ACID BURNS (unsealed wet cell batteries)
Acid in batteries is corrosive. It can cause serious burns
to the eyes and skin and can damage floors, furniture,
clothing and your wheelchair.
1. Use extreme care not to spill acid when you handle
batteries. Keep batteries upright.
2. Avoid contact of acid with bare skin or clothing.
3. Always wear rubber gloves and safety glasses
when you handle batteries.
4. If acid contacts your skin or clothing, wash immediately
with soap and water.
5. If acid contacts your eyes, immediately flood eyes with
cold running water for at least 15 minutes. Seek
medical attention immediately.
D. 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 jewellery that might contact battery
terminal and cause a short.
1. Lift batteries into battery compartment.
Batteries weigh up to 55 pounds (25 kg). Lifting batteries
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. Con-
nect 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
