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 charge as often
as possible.
Specification of the battery that we recommend:
Type:
Size:
Voltage:
Amp Hours:
Depending on the use, terrain and driving conditions, the batteries will provide a range of 12-18
miles of travel. However, even if the power chair is not in use, we recommend that the batteries
be charged periodically.
Note:
→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.
→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
into VDC (direct current).The batteries use direct current to run your power chair. 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 over-
charge the battery.
Note: The batteries will not be able to be charged after they are discharged to nearly zero voltage.
CHARGING INSTRUCTIONS
To recharge the batteries, follow the steps below:
→Place your power wheelchair close to a standard electrical wall outlet.
→Turn the controller power OFF
→Plug the charger power cord (Round head) into the controller
→Plug the charger power cord into a standard wall outlet. A red and a yellow (if battery charge
is low) LED will illuminate.
→When charging is completed, the yellow LED will turn green.
