Charging Batteries - Sunrise Medical Quickie Q700-UP M Instructions For Use Manual

6.2 Charging batteries:

& Battery charger: Please read the owner's manual with the
charger supplied carefully. The general procedures and effects
for the interference with the chair and the batteries remain
valid.
Battery care plan
Below is set out a battery care plan for maintenance free
batteries. This has been agreed between Sunrise Medical and
the battery manufacturers, to enable you to get the best out
of your batteries. If a different care plan is followed, this may
result in lower than expected performance from your mobility
vehicle.
• Only use an approved Sunrise Medical charger compatible
with the vehicle to be charged.
• Charge your batteries every night, regardless of the amount
of use your mobility device has had during the day.
• Do not interrupt the charging cycle.
• If your mobility device is not required for use, it should
remain connected to the charger until required. This will
not damage your batteries, as long as the mains socket/plug
• is left switched on. Turning the mains socket/plug off, but
leaving the mains cable plugged in will eventually deplete
your battery charge.
• If you leave your vehicle for an extended period (more than
15 days) charge the batteries fully and then disconnect the
main battery lead.
• Failure to allow for recharge will damage the batteries and
can lead to shortened distances and premature failure.
• Do not top up the charge of your batteries during the day.
Wait until the evening for a full overnight charge.
• As a general rule, maintenance free batteries take longer to
fully charge than "wet" lead acid batteries.
• The battery terminals need to be checked regularly for
signs of corrosion. If any corrosion is apparent, then clean
the terminals completely and re-grease the terminal using
Vaseline petroleum jelly, not ordinary grease. Ensure that
the terminal nut and bolt, cable clip and exposed cable are
completely covered with jelly.
• Following all the points above should result in a healthier
battery, greater range for the vehicle user and a longer life
for your batteries.
Connecting the battery charger
Procedure for connecting the charger and charging
• Switch off the wheelchair controller. & Controller:
• Connect the battery charger round output plug to the
charging socket on the front of the joystick module, (Fig.
12.8-12.9). & Controller:
• Connect the charger to the mains supply by means of the
mains plug and switch on.
For more information about the charger operation, consult the
instructions provided with the charger. & Battery charger:
Depending on how depleted the batteries are, it may take up
to 12 hours to fully charge the batteries again.

DANGER!
• Make sure the cord is located so that it will not be stepped
on, tripped over or otherwise subjected to damage or stress.
• Do not rest a battery on top of the charger.
• Do not stand the charger on a carpet or other soft surface.
Always place it on a hard flat surface.
• Do not operate the charger if it has received a sharp blow,
been dropped or otherwise damaged in any way. Take it to a
qualified technician.
• Never place the charger directly above the battery being
charged; gases from the battery will corrode and damage
the charger.
• Never charge a frozen battery. A fully charged battery will
rarely freeze but the electrolyte of a discharged battery can
freeze at -9° Centigrade. Any battery that is suspected of
being frozen should be thawed completely before charging.
• Never sit with the charger on your lap when charging your
batteries
• The charger casing will get hot during its normal operation.
• Do not disassemble charger; only have it repaired by the
manufacturers. Incorrect re-assembly may result in a risk of
electric shock or fire.
• To reduce the risk of an electric shock, unplug the charger
from the outlet before attempting any maintenance or
cleaning. Turning off the controls will not reduce the risk.
• Never smoke or allow a spark or flame in the vicinity of
battery or charger.
• You should not charge your batteries in outdoor conditions.
• It is advised to use a smoke detector in the charging area.
Battery Charger
The external charger has been designed to charge two 12V Gel
type batteries connected in series (= 24 V).
The chargers have features which prevent hazards or accidents
occurring as a result of connecting batteries the wrong way
round, overheating caused by fault conditions or attempting to
charge wrong voltage batteries.
The majority of charger sizes are electrically double insulated
and no earth connection is required. Some larger sizes may be
electrically earthed and this will be clearly stated on the label.
If your charger has been specified for use in Continental
Europe it will contain a European two pin plug which does
not have a fuse. In this case the fuse is located in the fascia
panel of the charger.
Country specific information: UK
The 3 pin UK mains input plug contains a replaceable fuse.
The rating of this fuse is shown on the charger label.
DANGER!
• As with all mains powered electrical equipment, always
replace blown fuses with the same type and size of fuse as
specified.
• Fitting of different fuses can result in an increased fire risk,
damage to the charger or failure of the charger to operate
properly.
