To charge your battery:
Your battery has a wiring harness attached to it that has “piggyback” terminals
on it, enabling you to keep the power cord from the unit attached to
the battery at all times, as well as having the wiring harness with receptacle
for your charger attached at all times. To charge, simply couple the end of
the charger with the end of the wiring harness. It is normal for a green light
to appear on the charger at this time. Once connected, plug the transformer
end of the charger into a 110 volt AC wall outlet. You will see a red LED light
appear on the charger at this time. When your battery is fully charged, this
red light will change to green. Depending on the condition of your battery, this
process can take up to 20 hours to complete. At this time, you can disconnect
the charger from the battery and wall outlet. However, no harm will come to
your battery if you leave it attached to the charger
