I bought this one for a friend and made a test charge on two pink protected UltraFire 18650 2600mAh.
Battery 1: New, about 4 cycles. Cutoff at 4.16V, 4.16V after a couple of hours resting.
Battery 2: Old, about 2 years, MANY cycles. Cutoff at 4.18V, 4.16 after a couple of hours resting.
I then used my Turnigy Accucel 6 to top them off.
Battery 1: 70 mAh
Battery 2: 73 mAh
Not a very scientific test, but still.
I like this charger. I doesn't overcharge and that to me is the most important part, feels safe. The cells are around 2400mAh so "loosing" about 70mAh I feel is OK as long as you can trust the charger not making a fire. From what I've read and with this test I certainly would like to recommend this one as a good cheap charger.
I ordered one off ebay last week. Got it for $13 with free shipping. The delivery estimate is almost 2 months, but it's already shipped. Can't imagine it taking more than a few weeks..
Hm, black one with white text? :| AFAIK, original WP2 is made from grey plastic (top part, and black bottom part) and "DC 12V" text is not written with white paint :~ Fake WP2?
Yup, perhaps new batch. But... I'm still leaning towards a fake WP2 :X Anyway, hope it works equally well for you, glenn, but yeah, keep eye on it while charging. Just in case ;)
SashiX, thanks for the heads up. I'll measure the charge current and voltage with my Fluke 189 multimeter. I'm very careful, especially with 18650's. I charge my batteries in my detached garage away from anything combustible. Paranoid is my middle name lol!
I finally got my charger. The only question is, real or fake? Question: For some reason I can't get images to display in this forum. I have no problem in other forums I belong to. What am I doing wrong?
I'm charging ultrafire 3200 mAh's I have on hand right now. I know they're not great batteries, but they're all I have right now and they do just fine in my Fenix TK35. I do have Xtar 2600's and Panasonic 2900's on order. Hopefully they will arrive soon. I'll measure voltage when charging is complete.
