Description And Use Of Battery Chargers - Invacare 3G Storm Series Owner's Operator And Maintenance Manual

DO NOT sit in wheelchair while charging batteries.
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 stop
charging when full charge is obtained.
There are some basic concepts which will help you understand this automatic process.
They are:
The amount of electrical current drawn within a given time to charge a battery is called
the "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.
NEVER leave the charger unattended when the charger circuit breaker is tripping
on and off. A condition between the battery charger and batteries exists. Contact
an Invacare dealer.
NOTE: If performing the charging sections 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
instructions.
NOTE: Have the following tools available:
• Battery Charger
• Extension Cord*
*NOTE: 3-prong plug, 15 ampere current rating; industrial type.
