BATTERY
We recommend that you use deep-cycle batteries that are sealed and maintenance
free for your power wheelchair. Both sealed lead-acid (SLA) and gel cell are deep-cycle
batteries and are similar in performance. Deep-cycle batteries are specifically designed
to provide power, drain down, and then accept a relatively quick recharge. Lead-acid
batteries should be charged as often as possible.
Specification of the battery that we recommend:
Type: Deep-cycle sealed lead-acid or gel cell
Size: U-1
Voltage: 12 V each
Amp Hours: 30-35 amp hours
Depending on the use, terrain and driving conditions, the batteries will provide a range of
15-20 miles of travel. However, even if the power chair is not used, we recommend that
the batteries be charged periodically.
Note:
B Do not use any automotive batteries. They are not designed to handle a long,
deep discharge and also are unsafe for use in power chairs.
B The useful life of a battery is quite often a reflection of the care it receives.
CHARGER
The battery charger takes the standard wall outlet voltage (alternating current) and
converts it to VDC (direct current). The batteries use direct current to run your power chair.
When the battery voltage is low, the charger works harder to charge the batteries. When
the batteries are fully charged, the amperage from the charger is almost at zero. This is
how the charger maintains a charge but does not overcharge the battery.
Note:
B The surface of the charger will become slightly hot during charging.
B Make sure the fan of the charger works properly for cooling the charger.
B The batteries will not be able to be charged after they are discharged to nearly
zero voltage.
B If your charger comes with two settings, 110V or 220V, always make sure you are
using the correct setting before charging.
Warning! Only use the off-board charger that is supplied with your power wheelchair.
Do not use an automotive-type battery charger. Use of any other charging unit voids the
warranty and could result in severe damage to the batteries, the HP-1, and may cause a
fire hazard.
