6400-03 batteries

Batteries are normally charged with the LI‑6020 battery charger. To charge the batteries:

  1. Select the proper voltage.
  2. 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.
  3. Plug the charger into mains power.
  4. The AC indicator light will illuminate. If the charge indicator lights up instead, you’ve got the wrong voltage selected.
  5. 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.)

A fully discharged 6400-03 battery requires about three hours to recharge. Four discharged batteries connected simultaneously require approximately 10 to 12 hours to recharge. Do not leave a battery on the charger for more than 24 hours after the charge light has gone out.

Storing the 6400-03 batteries

Store batteries fully charged, and in a cool place, if possible. For long term storage, place the batteries on the charger overnight every three months.

Replacing the battery fuse

There is a 10A automotive fuse located inside the metal cover of the 6400-03 battery. If the battery fails to power the LI-8100A, and will not light the charge indicator on the battery charger, check to see if the fuse has blown.

  1. Cut the black tape between the two halves of the battery.
  2. Remove the top half of the battery (the half with the connector), and lay it to the side with the wires still attached.
  3. Look at the fuse or check it with an ohm meter to determine if it has blown.
  4. Replace the fuse (part number 438-03142) if needed.
  5. Tape the battery covers together with black electrical tape.
