Battery Charger - Otto Bock B400b400 Instructions For Use Manual

Usage
• The batteries can be charged at any time, regardless of
the remaining battery capacity.
It takes about 10 hours until a discharged battery (only
•
1 flashing segment) is completely charged. When the
charging process is complete, the battery charger can
remain connected to the power wheelchair with no risk
of overcharging or damaging the battery. The battery
charger features a programmed recharging phase that
will maintain the battery capacity at the level that has
been reached.
• If the power wheelchair is used every day, the battery
should be charged every night.
• Never discharge the batteries completely (deep dis­
charge).
• The batteries will gradually discharge if the wheelchair
is not used for extended periods of time. If the power
wheelchair is not used for an extended period, the bat­
teries should be charged 1 x per week to maintain their
capacity.
• The fuse should be removed if the wheelchair is not
used for more than 3 days.
• The power wheelchair control unit must be switched off
while the batteries are charging to allow all of the char­
ging current to be fed into the battery.
