General Batteries/Storage
• CAUTION that a battery drains on its own and a discharged battery can
freeze and burst when it is cold. If the wheelchair must be stored without
being used for a long period of time, the batteries should always be charged
up once per month so that they do not incur any damage.
• The wheelchair must not be stored in a room where condensation arises
(mist or dampness on the surfaces) e.g. laundry rooms or similar rooms.
• The wheelchair can be stored in an unheated room. What is best for the
wheelchair from a corrosion standpoint is that the room be some degrees
warmer than its surroundings, which keeps the room drier.
• If the wheelchair is equipped with acid batteries(liquid electrolyte), the acid
level should be checked regularly. If the wheelchair is equipped with GEL
batteries, the fluid level need not be checked.
• The lifespan of the batteries depends entirely upon regular charging.
Short-term storage
In order for the charging procedure to give a battery with good capacity, the
temperature in the storage room must not be lower than 41 F. Storage at under 41
F increases the risk of the battery not being fully charged when it is to be used
as well as increasing the risk of corrosion.
Long-term storage
Storage can occur in an unheated room, however the battery should be mainte-
nance-charged at least once per month.
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.
