General - batteries/storage

• 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
damaging them.
• 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 sur-
roundings 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.
short-term storage
For the charging process to produce a battery with good capacity, the tempera-
ture in the storage room should not be lower than +5 degrees. If it is stored at
a temperature below +5 degrees, there is a higher risk that the battery has not
been fully charged when it comes to be used and also a higher risk of corrosion.
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.

Be careful if using metal objects when working with batteries. A short-circuit can easily cause an
explosion. Always use safety gloves and safety goggles.
