Batteries are normally charged with the LI-6020 battery charger.
1. Select the proper voltage.
Make sure that the voltage selector slide switch on the back of the LI-6020
battery charger is set to the appropriate line voltage (115 or 230 VAC) and the
correct fuse is in place.
2. Plug the charger into mains power.
The AC indicator light will illuminate. If the charge indicator lights up in-
stead, you’ve got the wrong voltage selected.
3. Connect the batteries.
The CHARGE indicator illuminates if any of the batteries connected to the
charger are being charged. One method for testing a battery’s charge is to
connect it to the charger when no other batteries are attached. If it is charged,
the CHARGE light comes on for only a few seconds, if at all. If the CHARGE
light does not come on, either the battery is fully charged, or the battery’s fuse
has blown. (To test, plug the battery by itself into the LI-8100A, and power it
on. If nothing happens, then the problem is the fuse, or the battery is dead.)
