Maintaining battery box performance
If the device will not be used for prolonged periods, ful-
ly charge the battery in the battery box (charge time
ca. 5-6 hours) and then raise and lower the seat frame
3 times while it is unloaded. Repeat this procedure at
least every 12 months. This preserves the service life
of the battery.
