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.
Sunrise Medical does not recommend the use of wet cell batteries
on this chair.
C. CONNECTING BATTERIES
1. Batteries weigh up to 39 lbs. Take care to avoid injury when
lifting.
2. Always wear rubber gloves and safety glasses when you han-
dle batteries.
3. Before working with batteries, remove all metal effects, such
as necklaces, rings, watches, pins and other metal jewelry
that might contact battery terminal and cause a short.

1. Replacing the Batteries
a. Lift batteries into battery compartment.
b. Attach the battery harness to the battery post. Connect red
to the positive terminal and black to the negative terminal.
c. Cover the battery posts with insulating caps on the harness.
Connect and disconnect battery cables with caution. Do this for
each battery. Tighten all terminal fasteners using two 1/2" box end
wrenches to 60 in-lbs (6.8 N.m). 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.
D. CHARGING BATTERIES
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 emits explosive hydrogen gas during charging. 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
battery during charging.
•
Never allow metal tools or chair parts to make direct
contact across both battery terminals.
4. Never look directly into the cells when charging batteries.
ALWAYS:
5. 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.
NOTE– Always remove and reattach the negative cable (black cable) first.
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.
6. Make sure to allow enough time to fully charge batteries.
7. To charge batteries, use the off-board charger by plugging
off-board charger plug into the off-board charger socket.
