18. Charging the maintenance free batteries
This chapter provides information of maintenance free battery for the
assistant.
The amount of charge in your maintenance free batteries is depending on a
number of factors, including the way you use your wheelchair, the temperature
of the maintenance free batteries, their age and the type of maintenance free
batteries used. These factors will affect the distance you can travel in your
wheelchair. All wheelchair maintenance free batteries will gradually lose their
capacity when they get older. The most important factor that is reducing the
life span of your batteries is the amount of charge you take from the batteries
before you recharge them. The maintenance free battery life is also reduced
by the number of times you charge and discharge the batteries. Normally the
amount of cycles is between 300 and 700 times. To make your maintenance
free batteries last longer, do not allow them to become completely discharged.
Always recharge your maintenance free batteries promptly after they are
discharged. If your battery gauge reading seems to fall more quickly than
usual, your batteries may be worn out. If you wheelchair shows these
indications, please contact your local authorized supplier to have the
maintenance free batteries checked.
If the parking brake is released (free-wheel mode), the wheelchair cannot be
driven by the electronics. Therefore, the release of the brakes should only
be done in emergency cases and or for servicing. If the user is on board, the
parking brakes should always be attached.
If you want to put the wheelchair into freewheel mode, be sure to switch
the electronics off first. Leaving the electronics switched on will result in a
large resistance whilst pushing in freewheel mode.
Always make sure that, when positioned on slopes, the brakes are attached
(no Freewheel). If the wheelchair is in freewheel mode, there is a risk that
the wheelchair might start to move in an uncontrolled way. This might lead
to personal or material damage.
