NOTE–
Always remove and reattach the negative cable (black cable)
first.
NOTE–
Batteries should never be left for long periods in the dis-
charged state. Unused or stored batteries should be given a
charge once per month.
5. Make sure to allow enough time to fully charge batteries.
6. To charge batteries, use the off-board charger by plugging off-
board charger plug into the off-board charger socket.
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) 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.
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 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
charging when it is
not necessary.
WARNING
Never connect a life support or auxiliary device to a wheelchair bat-
tery. The electrical system may fail, and result in severe injury to or
death of the user.
B. CHARGING BATTERIES
WARNING
To avoid 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 touch the
charger after it is connected to an electrical outlet.
1.
Never
connect or disconnect charger from battery while
there is power to the charger.
2.
Never
use an extension cord. Use of an improper cord could
damage the charger or cause a fire or electrical shock.
3. A battery can emit explosive hydrogen gas if the wrong charg-
er is used. To reduce the risk of fire or explosion:
• Make sure area is well vented. Never charge battery in a
closed-in area.
• Never smoke or allow a spark, flame or high heat near bat-
tery during charging.
• Never allow metal tools or chair parts to make direct con-
tact across both battery terminals.
ALWAYS:
4. Use the charger that comes with your wheelchair. Read and
follow all instructions and warnings. Make sure the room is
well ventilated. Turn off all power to your chair.
