Got this charger today and when plugged in the left side bay led stays red while the right side is green. When 18650's are put in the left channel stays red while the right channel turns from green to red. After charging for 4 hours @ 500mA the battery on the left went from 3.65v to 3.70v the one on the right went from 3.66v to 4.05v. Is the left bay fried or am I doing something wrong? The 18650's are brand new Eagletac 3100mah.
Any help from owners of this charger?
