Charging Batteries

ƽ WARNING

Never attempt to recharge the batteries by attaching cables directly to the battery

terminals or clamps. Use the recharging plug located on the front of the joystick.
DO NOT attempt to recharge the batteries and operate the power wheelchair at

the same time.
During use and charging, unsealed batteries will vent hydrogen gas which is

explosive in the right concentration with air. Follow the manufacturer's charging

instructions.

CAUTION

Always charge new batteries before initial use or battery life will be reduced.

NOTE: As a general rule, batteries should be recharged daily to assure the longest possible life and

minimize the required charging time. Plan to recharge the batteries when it is anticipated the

wheelchair will not be used for a long period of time.
The range per battery charge using recommended batteries should be approximately 5 to

9 hours of typical operation. Extensive use on inclines may substantially reduce per

charge mileage.

Description and Use of Battery Chargers

The charger automatically reduces the charge from an initially high rate to a zero reading

at a fully charged condition. If left unattended, the charger should automatically shut-off

when full charge is obtained.
Some basic concepts which will help you understand this automatic process are:
The amount of electrical current drawn within a given time to charge a battery is called

“charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is

high, as indicated by the green light on the charger. Initially, the green light will stay

illuminated for a short period of time followed by a longer period of off time. As a charge

builds up, the charge rate is reduced, and the green light will stay illuminated for a longer

period of time followed by a shorter off time.
NOTE: If performing the charging procedures independently, READ and CAREFULLY follow the

individual instructions for each charger (supplied or purchased).
NOTE: If charging instructions are not supplied, consult a qualified service technician for proper

procedures. Required items:
