Xtar WP2 Charger

Hmmm , its more sensitive to internal resistance [ so if a cell has higher internal resistance it will terminate charging earlier ] Xtar ...

The Trustfire will continue charging to termination voltage ... And then Trickle charge ..

While the Xtar will stop charging on termination . [ small , very small monitoring current = not worth worrying about ]

I have both and use both ... Sometime's you want the battery to terminate @ 4.2v [ battery tests and such ]

If you wish to check on the internal rersistance , throw it in the Xtar and see where it terminates ...

My WP2 sample does the following (i use the MP1 more often):

XTAR 2400mAh protected 4,19V cutoff (few cycles)

Hi-MAX 2600mAh protected 4,19V cutoff (few cycles)

Salvaged sony unprotected from laptop 2000mAh = 4,20 cutoff (many cycles, 1y old or more, probably way more)

trustfire grey 16340 protected charged with help of a a spacer 4,17V

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.

Where did you buy it? Manafont only sells US plugs so i would have to buy a converter piece.

anyone knows about this one? http://www.manafont.com/product_info.php/trustfire-multifunction-liion-battery-charger-tr003p4-110240vdc12v-p-7339

I (also) have a EU version, very reliable

Look at ebay

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..

atbglenn, thanks for the link.. will keep that in mind.. only 13dollars is a pretty good deal

Sure thing :) I used the "best offer" thingy and saved 69 cents off his $13.69 "buy it now" price. I offer him $11, he counter offered at $13..

I even just tried a 10 dollar offer.. will wait for him to answer it...

anyway a 13 dollars xtar isnt to bad either.

Best of luck with your offer! Maybe you'll do better than I did :)

Thanks..;)

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?

Fake?? I guess it could be. Maybe they changed the design slightly?? I guess I'll know more when I receive mine..

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!

Paranoid? Don't think so, we just need to be careful with this things. Better safe than sorry. :bigsmile:

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?

Similar to "new"(?) WP2 II. Could be slightly redesigned body.

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.

Keep us informed ;)
