I was charging two old 18650 laptop cells (steady RED on, charging) for about 20 minutes then suddenly one bay's RED(only RED) led started to blink. I tried to look in the owner's manual and the following was printed: No Batteries . . . Green on / Red fast blink
Charging . . . . . Green off / Red on
Full . . . . . . . . .Green on / Red off
Defective Cell . .Green on / Red fast blink
This is the first time it happened. I have lots high IR, defective and rejected cells already but never a BLINKING RED ONLY. I removed the cell and put it back then a steady red for a few minutes then the BLINKING RED ONLY came back. With the both cradles empty, it's back to normal green on/ fast red blink (NO BATT). What does this mean?
