Charging Batteries - Invacare TDX Series Owner's Manual

SECTION 7
CHARGING BATTERIES (FIGURE 12)
NOTE: New batteries MUST be fully charged prior to initial use of the wheelchair.
Never attempt to recharge the batteries by attaching cables directly to the
battery terminals or clamps. Always use the recharging plug located on the
the back of the joystick.
DO NOT attempt to recharge the batteries and operate the power wheel-
chair at the same time.
During use and charging, unsealed batteries will vent hydrogen gas which is
explosive in the right concentration with air.
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 wheel-
chair 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.
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 breaker has tripped. A fault
condition exists. Unplug and discontinue using immediately. Contact an
Invacare dealer.
