space between them. Correct polarity and a good connection will be your
reward.
6. Determine the type of battery you wish to charge. When certain
press the Select Battery Type button. The most common is the
Flooded kind, distinguished by removable filler caps (6) or two (2)
manifold covers (Maintenance-Free) which should not be removed
unless specifically allowed by the battery manufacturer. The second
most popular is the
Absorbed Glass Mat (AGM) sealed-valve
regulated type. Lastly is the sealed valve regulated GEL battery.
Note : If unsure of your battery type, check with the battery seller,
manufacturer or our Tech Support before proceeding further. The normal
(default) setting of your charger is GEL, as this is the lowest voltage output
and thus the one least likely to cause your battery to be overcharged,
should you incorrectly select the wrong battery type. However be aware
that using the wrong setting for a particular type battery can dramatically
shorten its life and/or cause potentially explosive gas to be emitted from
the battery.
7. After selecting both battery type plug the unit’s power cord into a standard
– grounded 120 Vac electrical outlet. The Power ON LED Indicator will
light
GREEN . If it does not light GREEN check the outlet to be sure it is
functioning. In addition, be sure if outlet is controlled by a switch, no one
will accidentally shut off the power to the outlet. Check for correct polarity
= (no ERROR
RED LED Indicator). If ERROR Indicator is lit, reverse the
charger’s output connections to the battery.
8. The Charge – Float LED Indicator will light GREEN . The charger will
now begin charging by first checking the battery to determine its voltage
and ability to accept a charge. Should the battery not have a normal fully
discharged voltage (
31.5V [36271] / 42.0V [48021] minimum) the unit will
begin charging in the “Soft-Start” mode to determine if the battery can
be safely charged. If it cannot, the Power ON – Error LED will flash
RED
and charging will be stopped. Battery should be carefully checked under
a load by a qualified person before further attempting to charge it.
9. Note : If the battery does not have a minimum no load OCV (Open
Circuit Voltage) of 36 Volts / 48 Volts , the ERROR LED will light RED
and charger will reject battery.
10. No further effort should be made to charge this battery with this charger
or any charger. Discard this battery, unless it has just been subjected to a
long period of continuous discharge under a load such as can occur with
