How to read the charger touchscreen
If your charger has a touchscreen, the screen shows the status of the battery and
charger. When the room gets dark, the charger display gets dim; see next page.

charger

Charger has a problem, and
cannot charge the battery.
What to do
Insert the battery into the charger. Leave one battery in the
charger while you use the other battery.
Let the battery charge. This can take up to 4 hours.
Leave battery in the charger until ready to exchange battery.
Let the test run, which can take up to 12 hours. Test verifies
battery function as part of normal routine. After test, battery
will be charged, which can take another 4 hours. So the whole
process can take up to 16 hours.
If you need to use the battery sooner, remove battery from
charger as soon as you see this on the screen. Then put the
battery back into the charger to skip the test and charge the
battery. The test will be performed the next time the battery is
plugged into the charger.
The battery may charge, but will take longer than normal.
Battery can be used, but should be replaced.
Call ZOLL for a replacement battery.
