I just bought a laser that included 2 "Ultrafire" 18650 batteries, and 2 single incredibly cheap chargers for the same.
Just how how are the chargers supposed to work? After running both batteries down to approx 3.7 volts, I tried to charge them in the chargers. Both of the chargers just sit there and blink red. The Killawatt thingee that I have the chargers plugged into doesn't show any current being drawn. How does charger indicate that a battery is charging, charge complete, bad battery?
I know the batteries, and chargers are crap, but I have gotten ones in the past that at least worked. I plan on returning either the chargers or batteries, but I don't know if the charger is at fault since I have no clue what flashing red means.
Looked on line for instruction, but nothing specifically said what the indicator light signified.
