6.7.1 Safety Instructions
NOTICE
Unauthorised battery replacement
Damage to the battery due to user error
► Replacing the battery or modifying the battery installa­
tion position may only be performed by qualified per­
sonnel trained by the manufacturer.
► 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 independ­
ently.
6.7.2 General
The standard version of the power wheelchair is equipped
with 2 maintenance-free AGM batteries with a capacity of
50 Ah (C5)
.
Optionally, the power wheelchair can be equipped with
maintenance-free gel batteries with a capacity of
63 Ah (C5)
.
The batteries are located under the seat of the power wheel­
chair, below the battery cover.
Prolonged driving at the lower end of the battery indicator
results in deep discharge which causes battery damage. If
the power wheelchair is being driven when the battery is low
the control unit switches to creep speed to save power.
6.7.3 Battery charging information
The range of the power wheelchair is determined by the bat­
tery capacity. The battery capacity is influenced by many
factors. In addition to the temperature, battery age and driv­
ing conditions, the charging cycle also has a pronounced
effect on the capacity and therefore on the range.
At temperatures of
< 0°
the battery capacity drops by up to
35%
in relation to the capacity for an outside temperature of
20°
. This shortens the range of the power wheelchair
accordingly. Moreover the battery capacity 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:
