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.
