Although both battery types may be removed for charging the Li-ion type can and should ideally be charged in
chair.
Both chargers will accept an input voltage between 100 and 240V and therefore suitable for both 110 and 240v
without alteration. For UK use the 3-pin plug supplied. If you need a 2 pin plug (for some other countries) you
can simply undo the central screw (screwdriver required) that holds the plug together and inside you will find a
2 pin plug as shown below.
Both batteries will show the remaining power on the top of the battery in the form of 5 illuminated bulbs. Press
the green button on the top of the battery to see the power remaining. 5 bulbs illuminated means fully charged
and one means charging will be required shortly.
For convenience the power remaining gauge, also appears on the joystick control unit shown as a percentage.
Do not confuse this with the ‘speed selected’ display
on the left, shown in bars.
NMH (Nickel Metal Hydride) Battery Charging
To remove the battery, make sure the joystick power switch is off. Open the battery box rear flap, press the
yellow button and withdraw the battery.
Place the battery in the charger and follow the instructions on the charger. The battery will typically enter a
‘F
ast Charge
’
state (fully charged in and 2-3 hours), however occ
asionally the battery will begin a ‘
Refresh
Charge
’ which takes
8-10 hours. This normally happens after significant use (over many months) and allows the
battery to refresh the battery cells, ensuring that the battery can recharge every cell, rather than a smaller
percentage, which can lead to poor battery performance (as with most mobile phones, etc.).
