BATTERIES & CHARGER

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:

Size:

Voltage: Amp Hours:

Deep-cycle sealed lead-acid or gel cell U-1

12 V each

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:

BDo not use any automotive batteries. They are not designed to handle a long, deep discharge and also are unsafe for use in power chairs.

BThe 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:

BThe surface of the charger will become slightly hot during charging.

BMake sure the fan of the charger works properly for cooling the charger.

BThe batteries will not be able to be charged after they are discharged to nearly zero voltage.

BIf your charger comes with two settings, 110V or 220V, always make sure you are using the correct setting before charging.

ZWarning! 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.
