Owner’s Manual Permobil K/C300 Operation
81
Observe care in the use of metallic objects when working with batteries. A short-circuit can easily
cause an explosion. Always use safety gloves and protective eye-glasses.
Only chargers with a max 10 A charging current (average value) may be used.
(The RMS value of the charging current must not exceed 12A.)
Charging must be done in a well-ventilated room, not in a wardrobe or closet. Charging must not
be done in a bathroom or wet room.
The charger’s charging cable must not be extended.
The charger can become hot and hence must not have anything covering it. The charger must be
positioned so that there is an air gap on all of its sides, including below (do not set the charger on
thick carpeting, for example).
The charger contact must be replaced if it is damaged or becomes hot during charging. Both the
contact on the charger’s cord and the wheelchair’s control panel should be replaced if one of them
is damaged or worn. Replacement must be performed by qualified personnel.
If the batteries become drained completely due to extended or heavy use, it is important that you
charge them up again as soon as possible since a complete loss of charge reduces the lifespan
of the batteries.
Battery Charging
The amount of charge in your batteries depends on a number of factors, includ-
ing the way you use your wheelchair, the temperature of the batteries, their age
and the way they are made. These factors will affect the distance you can travel
in your wheelchair. All wheelchair batteries will gradually lose their capacity as
they age.
The most important factor that reduces the life of your batteries is the amount of
charge you take from the batteries before you recharge them. Battery life is also
reduced by the number of times you charge and discharge the batteries.
To make your batteries last longer, do not allow them to become completely
discharged. Always recharge your batteries promptly after they are discharged.
If your battery gauge reading seems to fall more quickly than usual, your batteries
may be worn out.
