General Batteries/Storage
• Note 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 longer 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, 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 tem-
perature 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.
