WARNING
During all work on the electrical system of the wheelchair, the connection
to the negative pole of the battery must always be removed.
WARNING
Take care when using metal objects in connection with work on the batte-
ries. Short-circuiting can easily cause an explosion. Always use protective
gloves and goggles.

General

• Batteries discharge themselves and must be charged and maintenance-char-
ged to prevent them from being damaged.
• The wheelchair must not be stored in rooms in which condensation occurs
(mist or moisture on surfaces), i.e. wash-houses or similar rooms.
• The wheelchair may be stored in an unheated room. From the point of view
of corrosion, it is best for the chair if the room is a few degrees warmer than
the surroundings, which keeps the room drier.
Short-term storage
In order for the charging process to produce a battery with good capacity, the
temperature in the storage room should not be less than 41°F. Storage at less
than 41°F increases the risk that the battery is not fully charged when it is used
and also increases the risk of corrosion.
Long-term storage
The chair may be stored in an unheated room but the battery should be mainte-
nance-charged at least once per month. See also Short-term storage above.
