Batteries & Charging
8.1
Batteries
Your power chair uses a pair of high quality long lasting gel cell batteries that are sealed and
maintenance free. Your power chair has a 24V system which is supplied by two 12V batteries. There
is no need to check the electrolyte fluid level they contain. Despite their similarity to automotive
batteries, they are not the same. Automotive batteries are not designed to handle a long, deep
discharge, and are also unsafe for use in power chairs.
WARNING! Battery posts, terminals, and related accessories contain lead and lead
compounds, wash your hands after touching.
WARNING! Corrosive chemicals are contained in the batteries. Use only AGM or
gel-cell batteries to reduce the risk of leakage or explosive conditions.
WARNING! When fitting alternate batteries, ensure their terminal posts cannot
touch any part of the wheelchair frame.
STOP! Automotive batteries and chargers are unsafe for use in power wheelchairs
8.2
Battery Charging
We recommend using only a high quality intelligent battery charger that is compatible with your
power chair’s batteries. Only use the supplied off-board charger unless otherwise approved by
Magic Mobility. Do not use an automotive-type battery charge.
The charger will not operate after the batteries have been discharged to an extremely low voltage. If
this happens, call your Magic Mobility Dealer for assistance.
8.3
Battery Run-In
Proper care of the battery during the 'run in' (initial care) period is particularly important for battery
life.
Procedure:
Ensure the Battery is fully charged before the first use,
Use the chair normally during the day, avoid excessive loads during the first 5 cycles,
Charge the chair fully overnight, checking that the charger indicates that the battery is fully
charged (enters float mode),
Repeat steps 2 and 3 for the first 20 times (cycles) to complete the 'Run in' procedure.
Notes:
The new battery will take longer to achieve the full charge, but the time required will improve.
Initially you may find that you have to limit the amount of use during the day for the full charge to be
achieved.
The Battery capacity is reduced when new, this is normal and will improve during the run-in process.
