– BATTERIES
5.1.1 - Batteries
Your wheelchair is equipped with
sealed, maintenance-free deep cycle batteries
that are in conformity with air
transport standards DOT and IATA.
These batteries have been developed especially for propulsion of power wheelchairs:
-
« cycle » means that they are able to provide saved energy over a long period of time, compared to
starter batteries which provide a high quantity of energy for only a few minutes.
-
« sealed » means there is no risk of acid leaking or evaporating from the batteries during charging or
if the wheelchair over turns.
-
« maintenance-free » means that it is not necessary to monitor the level of the batteries:
Care is required to ensure proper charging and discharging.
These two operations determine the durability of your batteries and the autonomy of your wheelchair.
Reminder: the use of acid batteries is prohibited with this wheelchair.
5.1.2 - Use and Charge of the Batteries
The propulsion of your chair is provided by 3 batteries.
Their durability depends on several factors:
1) The product quality:
Use only original batteries that are in conformity with the manufacturer
’s technical specifications.
Using batteries of inferior quality may damage the electronics or interfere with the
wheelchair’s operation.
2) The quality of discharge.
The discharge indicator on your display provides you with valuable information.
Warning
: driving for a long time with the discharge indicator on red results in deep discharge that irreversibly
damages the batteries
’ durability.
3) The number of charging cycles: charge sensibly.
The durability of the cycle batteries depends partly on the number of « charge/discharge» operations but also
on the extent of every discharge.
Thus a battery which is 100% discharged will have a life expectancy of only 200 cycles,
while the same battery which is only 75% discharged is good for 275 cycles.
A 50% discharged battery will give 450 cycles.
Ideally the batteries should be charged when the discharge level is between 50 and 70%.
In practice this means you should charge your batteries as soon as t
here are only red lights on the display’s
discharging indicator but not before that.
The battery gauge
The battery gauge indicates how much battery charge remains.

Indicates
Battery full
Battery almost full
Battery half full, drive to a charger
Battery low, recharge soon
