Hi, 2 weeks ago i recieved my first flashlight set- fenix15, wf-139 charger and 2 protected 18650 fireworm(3000mah) batteries. After discharging one battery down to 2.8v( i know i usually shouldnt go that far), i started to charge it and after 2 hours she was about 3.7v. i put her back into the charger and 3-4 hours later, charger was still blinking red.that seems to long so i took her out in order to measure voltage again, and guess what- voltage of the cell was 0.5v!i tried to put her back in the charger, but this time charger light shown solid green. of course, voltage was to low for charging again. what could happend with a cell? have i done anything wrong? i guess i cant do nothing about her now...
