118444 Rev. B27Q M - 7 1 0 / 7 1 5 H D / 7 2 0X. BATTERIES• Never unplug charger by pulling on the electrical cord. Thiswill damage the cord.• Never open a charger or attempt to repair it yourself. Returncharger to Sunrise or have repairs made only by a qualifiedperson.• 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 willrarely freeze, but the fluid in a discharged battery can freezeat 16 degrees Fahrenheit (minus 9 degrees Centigrade). Ifyou suspect a battery is frozen, thaw it before charging.WARNINGWet cell batteries generate explosive gas while charg-ing. Completely read and follow all warnings about thebatteries in this user instruction manual and any labelsapplied to the product. Failure to do so could result infire, explosion, injury and/or death.Sunrise does not recommend wet cell batteries.C. CONNECTING BATTERIES IN BATTERYCOMPARTMENTWARNING1. Batteries weigh up to 55 lbs. (25 kg). Take care to avoidinjury when lifting.2. Keep batteries upright. Take care not to spill acid (wetcell batteries).3. Always wear rubber gloves and safety glasses when youhandle batteries.4. Before working around batteries, remove all metalpersonal effects, such as necklaces, rings, watches, pinsand other metal jewelry that might contact batteryterminal and cause a short.1. Lift batteries into battery compartment.WARNINGBatteries weigh up to 55 pounds (25 kg). Lifting batter-ies may cause back strain. If you fail to heed thesewarnings severe injury may occur to you.2. Connect and disconnect battery cables with caution. Connectthe red lead to the positive terminal and the black lead to thenegative terminal. Do this for each battery.3. Tighten all terminal fasteners using two 1/2" box endwrenches to 60 in-lbs (6.8 N.m).4. Place the battery compartment lid on power base.PROHIBITED!Never make direct contact across both battery termi-nals, as an explosion may occur. A spark may result in anexplosion and/or fire resulting in severe injury or death.A. INTRODUCTION1. Notes–• Batteries supply the power for your chair. They contain afinite amount of energy and have limits on how long they canstore and supply energy.• You can charge batteries only a certain number of timesbefore 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 of50 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 sealedcase type. Do not use a car starter battery.• Group 24 batteries are a minimum requirement for powerseating.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 thebatteries 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 willgreatly reduce the life of your batteries.• Never let a battery sit in a discharged condition. Giveunused or stored batteries a full charge once per month.• Always fully charge the batteries. Avoid “topping off” withfrequent charges.WARNINGNever connect a life support or auxiliary device to awheelchair battery. The electrical system may fail, andresult in severe injury to or death of user.B. BATTERY CHARGERA battery charger produces a direct current (DC). When applied toa discharged battery, this reverses the chemical reaction that led toits 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 ifthe alternating current (AC) supply is higher or lower than110 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 maylead to an explosion or fire).• Never place a battery on top of the charger.• Never expose charger to rain or snow.
