When your batteries are fully charged you should have sufficient power to give you all
the mobility required in a day. It is important that you understand how your batteries and
charger work. Batteries must be charged before using the power chair for the first time
and are recommended to be charged up to 10 - 14 hours after each day's use.
Maintain the Batteries :
1. Batteries should be charged every night in a well ventilated room.
2. DO NOT place the power wheelchair near radiators or open fireplaces while charging.
3. DO NOT smoke or permit open flames in the immediate vicinity.
4. Turn the chair controller power off before charging.
5. It is advisable that the batteries be charged for a minimum of 10 hours per night to ensure
full battery storage capacity. The battery charger is an automatic current limiting device
and will shut off when the batteries are fully charged.
Charging the batteries :
1. Position power chair next to a standard wall outlet.
2. Connect the battery charger to the wheelchair input battery charging socket, which is
located on the front of the controller.
3. Connect the battery charger to a standard wall power outlet.

During the recharge :
While the batteries are being recharged, a red light will appear on the battery charger,
indicating that the power is connected and charging is in progress.
At the end of the recharge cycle:

charged and ready for use.

when switched on.
When do the batteries need charging?

the controller will flash.

never use a charger other than the one supplied for that purpose.

charged for at least one day (10-14 hours) every month, minimum.
3. Periodically, check that the battery terminals are clean and the connections
are tight. Smear a thin film of petroleum jelly on the terminals to guard
against corrosion. Always wash your hands after handling batteries.
