I had to place solder beads on the positive terminals as the tenergy 18650 battery could not touch them. The positive terminals in the charger do not project far enough out away from the plastic casing.
Placed solder beads then filed them to provide more surface area contact to the battery. Also roughed up the neg posts. Seems to be working now. I'll probably look for other product where the positive terminals project way out- to make contact with the positive battery terminal.
Charges batteries to ~ 4.2. The LEDS go green but takes 6-8+ hours.
Works ok. Batteries come out easy.
I do enjoy the 18650. Tenergy seems to be good. The covers tic and tear easily. I'll try some others - if they look good, not too thick - my fenix's only go to about 18.4 diameter- Have fun.
Battery Superstore ships quick. Seem professional. They've delivered the product in good shape. I wouldn't hesitate doing business with them.
