Batteries and charging
Maintenance free battery care plan
1. Only use an approved Sunrise Medical
charger compatible with the vehicle to
be charged.
2. Charge your batteries every night,
regardless of the amount of use your
mobility device has had during the
day.
3. Do not interrupt the charging cycle.
4. If your mobility device is not required
for use, it should remain connected
to the charger until required. This will
not damage your batteries, so long as
the mains socket/plug is left switched
on. Turning the mains socket/plug off,
but leaving the mains cable plugged
in will eventually deplete your battery
charge.
5. If you leave your vehicle for an extended
period (more than 5 days) disconnect
the main battery lead.
6. Failure to allow for recharge will
damage the batteries and can lead to
shortened distances and premature
failure.
7. Do not top up the charge of your
batteries during the day. Wait until the
evening for a full overnight charge.
8. As a general rule, maintenance free
batteries take longer to fully charge
than lead acid batteries.
9. The battery terminals need to
be checked regularly for signs of
corrosion. If any corrosion is apparent,
then clean the terminals completely
(a wire brush is ideal) and re-grease
the terminal using Vaseline petroleum
jelly, not ordinary grease. Ensure that
the terminal nut and bolt, cable clip
and exposed cable are completely
covered with jelly.
10. Following all the points above should
result in a healthier battery, greater
range for the vehicle user and a longer
life for your batteries.
WARNING
Do not expose any part of the battery to
direct heat (i.e. naked flame, gas fire).
When charging always place on a
hard surface in a room with good
ventilation.
You should not charge your batteries in
outdoor conditions.
WARNING
Always use the charger that comes with
your wheelchair. Read and follow all
instructions and warnings.
