5. BATTERY CHARGING AND CARE

To Charge the Powerchair
1. Plug the charger's power cord in to the mains.
For Off-board chargers (UK).

lead in to the socket on the scooter body.
3. Switch on the plug socket at the mains.
Charger Light
• The charger light will illuminate orange to
indicate the batteries are charging. The
charging duration is about 8 hours, however a 12
hour charge is recommended for optimum
performance. The orange light will turn green
when charging is 95% complete.
Ensure that the charger is removed from
the mains and the powerchair after
charging. Failure to do this may flatten the

battery.

Suggestions
1. Do not disconnect the charger cord
until charging is completed and the light
is lit Green.
2. When fully charged the battery charger
will still trickle charge the battery for
optimum range.
3. Even when not in use, the powerchair
should be charged at least every week
to ensure battery longevity.
4. Ambient temperature will effect
charging time. Charging time will be
longer in cold environments.
5. The batteries carry a 1 year warranty
which covers manufacturing defects
only. It does not cover battery faults as
result of not following the guidelines
herein.

Warning
1. Only use the charger supplied with the
powerchair. Using the wrong type of
charger may cause damage. Never
disassemble or modify the powerchair.
2. Always charge the powerchair in a well
ventilated space. Avoid direct sunlight
or contact with water and moisture.
3. Do Not charge or operate the
powerchair in temperatures below -
10ºC or above 50ºC. Do not expose the
battery pack to these temperatures.
About the Batteries
• The batteries require charging every week to
ensure battery longevity.
• The batteries supplied by Drive Medical are
classified as safe for air transport under IATA
special provision A67.
Battery Care
1. You should recharge the batteries after
each time the powerchair is used to ensure
maximum battery range. The batteries
should be charged at least once a week
even if the powerchair is not used.
2. After charging or replacing a new battery,
drive the powerchair for a short period to
ensure battery capacity is sufficient.
3. In cold environments, the battery may
respond more slowly and range will be
reduced.
4. When driving on a gradient, the battery
gauge will fluctuate. This is a normal
occurrence.
5. Battery range is reduced when driving up
gradients or on rough terrain, as the
powerchair uses more power.
6. The batteries should not be charged for
more than 24 hours.
Battery Replacement
It is natural for the battery capacity to reduce with
time, even if the battery is charged as directed
above. When the battery range is about half of its
peak performance we recommend that the
batteries are changed. Continuing to use an old
battery will result in a rapid reduction in the range
of the powerchair and can cause excessive wear
and tear on other parts of the powerchair.
