7.9 Batteries/charging process
7.9.1 Safety instructions
CAUTION
Failure to check the charge level before putting into operation
Injury to the user due to stopping suddenly, problems due to unplanned stalling
► Check the charge level of the batteries before each use.
► Always make sure that the charge level of the batteries is sufficient for the planned distance.
► Never drive with the batteries almost fully discharged.
► When the batteries are almost fully discharged, charge them promptly.
NOTICE
Unauthorised battery replacement
Battery damage due to improper changes to the product
► Battery replacement may only be performed by the qualified personnel.
► The charging profile of the battery charger established at the factory matches the batteries included in the
scope of delivery and may not be altered independently.
7.9.2 General
The power wheelchair is equipped with maintenance-free batteries. See the section "Technical data" for the battery
capacity.
The batteries are located under the seat of the power wheelchair, below the battery cover.
Prolonged driving when the battery is low results in deep discharge and battery damage. If the power wheelchair is
being driven when the battery is low the control unit switches to creep speed to save power.
7.9.3 Battery charging information
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 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).
