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 wheelchair 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/ 8 -ampere 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 steadily on.
2.
With the AC connected and the charger connected to the batteries (via the charger
plug) - red and green LED’s are on. With the green LED 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 than the 8-amperes) and continues to monitor the
batteries.
Note:
the yellow LED will flash in a fault condition - check wiring and connectors for integrity.
