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.
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.
