20.3 Long term storage
The battery may be stored in an unheated room, but it should be charged at
least once a month for maintenance purposes.
•
Please note that a battery discharges itself and that a discharged battery
can burst when it is cold. If the wheelchair is to be stored unused for an
extended period of time, the batteries must always be charged once a
month to avoid them being damaged.
•
The wheelchair must not be stored in areas subject to condensation
(steam or moisture on surfaces), for example utility rooms or similar.
•
The wheelchair may be stored in an unheated room. From the point of
view of corrosion, it is best for the room to be a few degrees warmer than
the surroundings as this keeps the room drier.
• If the wheelchair is fitted with acid batteries, the acid level should be
checked regularly. If the wheelchair is fitted with gel batteries, the liquid
level does not need to be checked.
• The life of the batteries depends entirely on regular charging.
Be careful when using metal objects close to the batteries. A short circuit
might easily create strong sparks and can cause a fire. Should you need to
work on the batteries, use isolated tools and wear protective gear on
hands and eyes.
When the wheelchair is stored for a long term, we advise you to disconnect
the batteries from the wheelchair. This way the batteries will hold their
energy for a longer period.
When re-using the wheelchair, the batteries will be installed and fully
charged.
Ask your local authorized supplier to store and maintain the batteries if they
are not used for a long period (more than two months.)
