Invacare Harrier Plus User Manual page 55

New batteries need charging before your first journey and will not perform to their peak until the first six to
ten charging cycles have been completed.
To ensure long battery life DO NOT allow your batteries to become totally discharged. If your Powerchair is
not used for any length of time the batteries must receive a full charge once a month and remain fully charged
during storage.
For replacement batteries contact your local INVACARE supplier/dealer in order to ensure that the new
batteries are of the correct type and specification and are correctly installed and connected.
WHEN TO CHARGE:
Keep an eye on the battery charge indicator on the joystick box at full charge all six lights will be on (from
right to left: green, amber, and red). As the battery charge drops during Powerchair operation successive
lights will extinguish until eventually only the two red lights will be on. It means that you must charge the
batteries without delay. We strongly advise you, however, not to wait until this critical point has been
reached but to charge the batteries as early and as often as possible after you have used your Powerchair. If
you ignore the warning (only two red lights on), and the battery charge drops further to a level where it is no
longer sufficient to allow safe driving, the controller will automatically cut the power supply to the motors, so
that the Powerchair comes to an abrupt halt, and you may find yourself stranded in an unpleasant situation.
Also, if you run down the batteries to such a low charge, you will have greatly reduced their potential service
life.
Except in emergencies, NEVER drive on discharged batteries, this will add strain to them and reduce their life.
We recommend batteries should be charged every time the Powerchair is used, independent of the depth of
discharge. Depending on this and their capacity, a full charge on completely discharged batteries can take up
to approximately eight hours.
CHARGING PROCEDURES
IMPORTANT:
Before you attempt charging, ensure you read and understand the instruction manual supplied with the
Battery Charger.
