8.10.4 Battery charging information

The range of the power wheelchair is determined by the battery capacity. The battery capacity is influenced by
many factors. In addition to the temperature, battery age and driving conditions, the charging cycle also has a pro­
nounced effect on the capacity and therefore on the range.
Batteries reach their full capacity only after approx. 20 charge cycles. Only if the full capacity of the batteries has
been reached can the power wheelchair achieve the stated range.
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 hours until a discharged battery (only 1 flashing segment) is completely charged. When the
•
charging process is complete, the battery charger can remain connected with no risk of overcharging or dam­
aging the battery. The battery charger features a programmed recharging phase that will maintain the battery
capacity at the previously reached level.
• 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 unit must be switched off while the batteries are charging to allow all of the char­
ging current to be fed into the battery.

► Place the battery charger on a level surface.
► If you locate the battery charger near a window, protect it from direct sunlight.
► Avoid overheating of the battery charger. Do not cover the ventilation slits in the case.
► Switch the control unit off during the charging process so that all of the charging current is fed into the bat­
tery.
► Avoid dust, dirt and moisture.
► Only clean the battery charger with a dry cloth.
The battery charger is designed for maintenance-free and low-maintenance batteries.
