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 temperature, 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) batteries (located on the
•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, fur- niture, 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 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 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 cau- tion. Connect the red lead to the positive termi- nal and the black lead to the negative terminal. Do this for each battery.
