b
Charger is not plugged into a live AC outlet.
c.
Fault in Wheelchair Wiring. Poor or open
connections in the wheelchair wiring that
connects to the batteries; corroded
terminals, loose or worn plugs and
receptacles, loose or worn fuseholders.
(Have your dealer repair the wheelchair).
d.
Battery connections in wheelchair wrong
(reverse polarity).
e.
One or both batteries no longer serviceable
(voltage below 13 volts for a 24 volt system).
If the charger turns off before the batteries are fully
charged, it indicates one of the following:
a.
Charger internal thermostat turned the
charger off due to overheating because
charger ventilation openings are blocked.
After the charger has cooled down to a safe
temperature, it will automatically restart. If
the charger repeatedly overheats, it may be
malfunctioning.
b.
The AC power was interrupted during
charge.
c.
The DC cord charging plug accidentally
disconnected during charge.
d.
Fault in Wheelchair wiring. The wheelchair
charging circuit has high resistance,
corroded or loose connections; loose or
worn wheelchair charging receptacle, loose
or worn wheelchair fuseholders.
e.
The battery has been allowed to sulfate,
Charge the battery no less frequently than
once every three days when the wheelchair
is lightly utilized. Once sulfation is allowed
to take place, it may be partially reduced by
returning, temporarily, to daily charging.
The decrease in wheelchair range where the chair
loses power earlier and earlier in the day indicates
one of the following:
a.
The electrolyte level in conventional liquid
electrolyte lead-acid batteries was allowed
to drop below the top of the battery plates.
Add distilled water to just cover the tops of
the plates immediately upon discovery and
fill to the proper level with distilled water at
the completion of the very next charge cycle.
Battery capacity lost in this manner is
permanent and is not recovered with
additional charge cycles.
b.
Use of the wheelchair before the batteries
have been fully charged and the charger
turns off, shortens battery life and hastens
the onset of this reduced daily range.
Battery capacity lost in this manner is
permanent and is not recovered with
additional charge cycles.
c.
This is the normal wearout process for all
types of deep-cycle motive power batteries.
The charger operates through 14 hours before
tuning off. The YELLOW charge light turns off and
the RED fault light comes on. This indicates one of
the following:
a.
Batteries of higher than 85 amp-hour
capacity (20 hr. rate) can require more than
14 hours to charge.
b.
New batteries (5 cycles or Less) can require
more than 14 hours to charge.
c.
Very deeply discharged batteries (100%
discharged) can require more than 14 hours
to charge.
d.
Several failed cells in the batteries that do
not allow the charge rate to taper below 4
amps.
