CHARGING THE WHEELCHAIR BATTERIES
Charging the batteries is the most important part of operating and maintaining your new
wheelchair. Be sure you do it properly! As per international standards, it is recommended that
only a gel cell or sealed suspended lead-acid type deep cycle battery be used on the Wheel-
chair. These batteries do not require water and have no danger of spillage. They are also
approved by the Federal Aviation Administration for air travel.
Your wheelchairs comes equipped with the new

Introduction to Features of this Charger
Wheelchairs equipped with the RANGEMASTER III, fully automatic battery charger, have a 24-volt
Constant Current Charger. It is designed to operate from virtually any AC line source and provides a
constant charging output until the batteries are fully charged. This results in a maximum charge in a
minimum amount of time. Conventional chargers have a declining output proportionate to the charge
rate of the batteries.
The RANGEMASTER III is recommended for use with deep cycle, gel or sealed lead acid batteries,
and can be left "on charge" indefinitely without harm to the batteries. Plus, the RANGEMASTER
will operate from an AC line source as low as 90-volts and as high as 240-volts (50-60 Hz). Circuit
protection is built into the device to protect the circuitry with reverse polarity protection on both
input and output of the RANGEMASTER III charger.
This charger is provided with a pair of Light Emitting Diodes (LED’s) at one end which provide the
following indications:
1.
AC plugged in - yellow LED is on steadily.
2.
With the AC connected and the charger connected to the batteries (via the charger
plug) - yellow and green LED’s are on, with the green LED flashing to indicate charging.
3.
At full battery charge -the green LED turns to steady on, and the charger goes to a
float mode (charges at a lower rate) and continues to monitor the batteries.
Note:
The yellow LED will flash in a Fault condition - check wiring and connectors for integrity.
