BE CAREFUL TAKING APART CELLS!!!! If they are real 18650's then there is serious potential energy in them. I mean look at the post above where the ultrafire exploded and seriously hurt that old man
If you are going to take them apart, PLEASE BE CAREFUL, wear protective gloves, mask and gear. Do it outside in a well open ventilated area and down wind from people. Fumes may be given off if its a real 18650
I just get a laugh out of seeing all these different "inner" cells. Ultrafire is basically just like hmmmm what cell is cheapest this week? Ok we will wrap those and scam some more people
I did have one but I sold it off because the mineral oil kept making a mess everywhere. I'm not sure it would have been powerful enough to see through my cells anyway. Maybe though! That would be a good project. I think.
Hahaha this whole exposure might boost your sales Larry but it wouldn't be a bad thing since people would have quality cells!
I only own Pannys and Sanyo for 18650s. Have a nice MKNE 26650 and getting a few King Kongs. All my 16340s are AW or Efest IMR. Oh crap I just remembered I have some crapfires in 10440........need to get some Efest 10440s!!!!
Even the ones that are honest 18650 cells are just used laptop cells poorly pulled. I use "used" laptop cells, but the ones I use are Sanyo UR18650F, and when I pulled them, they only had been through ~20 cycles according to the counters in the battery pack. UR18650F are widely known as the best standard lithium ion cell, holding their voltage higher than others over the course of a discharge. But their capacity aint got nothing on the newer 3100 and 3400mAh cells, esp. when paired with a good driver!
Larry works hard to spread the good word about using these cells safely, I don't know why people keep buying off-brand batteries. If you can buy a toaster for $15, or a toaster bundled with a loaf of gasoline-soaked bread for $15, which would you choose? Sure, the gas-soaked bread is free, but how comfortable would you be with installing this gasoline soaked bread in your toaster?
Huh. I think I'll be bringing my Trustfire batteries to the battery recycling center once I can buy some new ones. The thing with the ****Fire brand batteries is they're inexpensive and more accessible. 6$ shipped for a pair of ****Fire brands vs 16-20$ for a pair of AW's and a lot of the places that sell good batteries don't ship to places like Canada.
On the subject of batteries then, are NiteCore batteries any good? I like the look of their 3400 mAh 18650's.
I find it odd that they only come in 700 mAh. I have good AA batteries that are 2560 mAh each and a AA is roughly the same size as a 18350 (18350 is shorter, but its also fatter). Is it simply because 18350's aren't common and therefor have less R&D?
