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 back
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.
CAUTION
ALWAYS charge new batteries before initial use or battery life will be reduced.
NOTE: For this procedure, refer to FIGURE 10.6 on page 72.
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.
