NOTE: For this procedure, refer to FIGURE 11.6.
The far right side of the display screen is the Battery Gauge Display (BGD). It provides
information on the remaining charge in the batteries.
At full charge, solid blocks fill in all ten
segments between E (Empty) and F (Full).
As the battery becomes discharged, the
segments will progressively disappear a
bar at a time until no segments appear
between E and F. At this level the user
should charge the batteries as soon as
possible.

Charging Batteries
WARNING
NEVER attempt to recharge the batteries by attaching cables directly to the
battery terminals or clamps. ALWAYS use the recharging plug located on 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.
CAUTION
ALWAYS charge new batteries before initial use or battery life will be reduced.
NOTE: For this procedure, refer to FIGURE 11.7 on page 81.
NOTE: New batteries MUST be fully charged prior to initial use of the wheelchair.
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.
There are some basic concepts which will help you understand this automatic process.
