Otto Bock Juvo, Instructions For Use Manual

Page: 53 / 124

At temperatures of
< 0 °C/32 °F
the battery capacity drops by up to
35%
in relation to the capacity for an outside
temperature of
20 °C/68 °F
. This shortens the range of the power wheelchair accordingly. Moreover the charge
level displayed on the control panel can differ more significantly from the actual battery capacity.
The following information should be observed for an optimal charging cycle:
•
The batteries can be charged at any time, regardless of the remaining charge level.
• It takes about 10 to 12 hours until a discharged battery (only 1 flashing segment) is fully 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 discharge).
• 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 batteries should be charged
1 x per week
to maintain their
capacity.
• After charging the batteries, the circuit breaker should be deactivated if the wheelchair is not used for more
than 3 days.
• The power wheelchair control device must be switched off while the batteries are charging to allow all of the
charging current to be fed into the battery.
