Hi Taz, I really don't think using the Wf-139 is a problem to recharge the 26650s, afterall, many use their Pila charger to charge them too. You'd have to use magnets connected to the 139's terminals, or create a couple of dummy 18650's and the magnets connected to the 26650's.
The thing is, it'll likely take quite a while to charge them. The 4Stevens charger can manually be set to output 500mA or 1000mA, which is another reason I purchased it. But the 4stevens is by no means the only solution for charging the 26650's. Hope this helps.
Using magnets is not a bad idea, I think I saw this setup somewhere, although I don't remember where. Does anyone have a quick guide on how to make them?
How much was the charger from 4Stevens? Do you have a link?
Taz, Here is the direct link to both items I purchased from them using coupon code, CPF8 I'm also a member of CPF, but I mainly like hanging on this forum much better. Also, if you look around the internet, there are other dealers that sell the 4Stevens items for slightly less money. But again, I used the coupon code for something like 8% off the total order.
Just got my two TF 26650s from DX. Took a while to get here, and they sent me the wrong items first. However, they made up for it and finally sent me the correct ones. I was in a spot with FIVE 26650 lights and only TWO Keygos 26650 cells. The Keygos cells work nice in my lights. However, after reading all the good reports here on the TF 26650, I placed an order with DX. Also, to back it up, I placed an order also with Manafont too..
Here are the ones from DX, and they look real real to me!!
I put them in a light without even charging them, and they fired right up.. Happy camper..
Hey CehowardGS, Nice package you received there. Glad they finally got you the correct items. I just purchased the same cells from Manafont the other day. The planets must have been in perfect alignment because they were shipped out in less than 24hrs. Hopefully they'll get here in not to long.
I also got a pair of TF 26650s coming from Manafont too. Wasn't sure what DX was going to do, so I backed it with an order with Manafont.
On the charger, I have had that for a couple weeks now. Really good as far as I can tell. My protected Keygos 26650 fit right in there and the charger lets me know when it is finished too. Plus, it can charge any kind of rechargable battery. No 9 volts. It was $25 shipped..IMO, a good deal..
If you want a good charger for 26650 its charges at 1.5 amps so it will charger alot faster then other chargers that charger from 0.5. 0.65 and 1 amp check out this link.
Two amp,s might be a bit much even for 26650, you might start loosing mAh i would not charge 18650,s at 2 amps not even my 3100's, but i see a lot of people buying 0.65 amp chargers for 26650's 15 plus hour charge time lolls.
You want to charge them as fast as you can but not shorten the life and not increase the IR of the batteries, 1.5 amps is as high as ill personal go for 26650,s and i normally balance charge my 26650 at 1 amp, or use the linked charger when my hobby charger is busy doing other things.
I just received my Int'l Outdoor order from 4/17/12 with my King Kong INR 26650 raised top and (2) ML-102 chargers (ordered "INR" and received "INR"). These raised top cells do not like to sit in the ML-102 charger very nicely. The raised top of the battery slides up off the positive terminal of the charger (because the terminal just barely hits the edge of the raised part). Seems the charger is really sized for 18650's.
Anyone else using this combination? Seems to me that for use with these raised top cells it would be best to file off some of the chargers rolled side (the way it's rolled to fit an 18650) to allow the 26650 to sit down lower.
Here's a photo trying to show the issue:
It's tough to see the chargers positive terminal, but you can see how the cell is raised up off the "rolled edge" of the side of the charger.
The length of the INR26650? Or the length of the charger? Or both? I'll see if I can get both tonight. My calipers are metal, so what is the best way to measure the battery without shorting it? Is a thin strip of paper sufficient?
