Battery Charging Procedure; Charge Rate; Achieving Maximum Range From Your Batteries; Fully Discharged Batteries - Sunrise Medical Magic Mobility Extreme X8 Owner's Manual

6.5 Battery charging procedure

Batteries charge via a socket within the joystick module
(see Figure 6.2). When the battery charger is plugged in,
the joystick recognises this, and chair driving is inhibited.
The following procedure should be followed when
charging your new powerchair:
1) Ensure the powerchair is turned off
2) Plug the battery charger into the charging socket on
the joystick and turn it on
3) Please consult the battery charger instruction, which
has been supplied with your powerchair, to ensure
you know how the charger indicates the batteries are
fully charged
Figure 6.3 - Charging socket
• Don't expose the charger to rain and snow
• Don't open the charger or attempt to repair it yourself
• Don't place the charger on the powerchair seat when
charging as it can become quite warm. Always place
the charger on the floor near the chair when in use
• Never use an extension cord or multiple power
boards. Only ever plug the charger directly into the
wall socket
• Always protect batteries from freezing and never
charge a frozen battery. The temperature at which
batteries freeze depends on numerous factors
including their chemical composition, charge level
and usage (flat batteries can freeze at just below
zero). Doing so can result in personal injury and
damage the batteries
• Try to avoid exposing your batteries to varying
temperature extremes. Batteries perform at their
best when charged indoors at around 20 °C
• Always fully charge batteries.

6.6 Charge rate

How fast batteries charge depends on their electrical
capacity, state of charge, electrolyte temperature and
internal condition. The charger DC output will also
significantly influence the charge time.
6.7 Achieving maximum range from your
batteries
Please note – always follow the run-in and charging
procedures:
• Avoid ultra-deep discharges (deep discharges reduce
battery life)
• Don't leave batteries at low charge for an extended
period. After using all day, always fully recharge
batteries overnight
• After batteries are discharged to a low charge, be
sure to recharge them to full capacity (this may take
more than 8 hours)
• Ensure that your batteries are fully charged prior to
using your chair
• Ensure your tyre pressure is correct for the weight
and the terrain that you plan to travel
• Try to maintain a constant speed and drive as
smoothly as possible
• Try to avoid inclines
• Limit the amount of baggage weight you carry.

6.8 Fully discharged batteries

• Never allow batteries to completely discharge.
Driving your powerchair until it has almost
stopped will greatly reduce the life of your batteries
• Don't operate the control system if batteries are
nearly discharged. Failure to comply with this
condition may leave users stranded in an unsafe
position, such as in the middle of a road
• Never leave batteries in a discharged condition. Fully
charge unused or stored batteries least once a month
• The charger will not operate once batteries have
been discharged to an extremely low voltage. If
this happens, call your Magic Mobility agent for
assistance.
