Notes:
• Do not use car batteries. They are not designed for managing a lengthy and deep discharge
and are also not safe for use on electric wheelchairs.
• The lifetime of a battery often depends on its care.
13.1 Charging
The battery charger functions at the normal voltage of a socket (alternating current) and
converts it into VDC (voltage direct current). The batteries use direct current to operate the
wheelchair. When the batteries are completely charged, the amperage of the battery charger
is almost zero. This allows the battery charger to maintain the charge but not overcharge the
battery.
Note:
The batteries cannot be charged after they have discharged almost to zero voltage
13.2 Charging instructions
To charge the batteries, follow the steps below to charge the batteries:
• Position the wheelchair close to a standard wall socket
• Switch on the controller
• Connect the power cable of the battery charger (round head) to the controller
• Connect the power cable of the battery charger to a standard wall socket.
A yellow LED and a red LED will switch on (if the battery charge is low)
• When the battery is completely charged, the yellow LED turns green
• Disconnect the battery charger cable from the wall socket when the batteries are
completely charged. (fig.27)
WARNING!
Do not use a different voltage input to the one indicated. Check the current input
voltage (110V or 220V) and adjust manually (fig.28)

13.3 Attention
1. Read all the instructions and warnings before using the battery charger.
2. Use the battery charger in a well-ventilated area.
3. To avoid injury, only charge lead-acid or gel batteries.
4. Disconnect the power after charging.
NB:
only use the battery charger provided by the supplier of the electric wheelchair. Use of any
other type of battery charger can be dangerous and requires the manufacturer's approval.
