I just bought these batteries from a U.S. seller in Virginia. What do you think will they be good quality batteries? Here is the linkage...eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

...same as madvapes sells. You saved 6 cents plus shipping. I doubt you'll have any problems with them, but if you do there's no exchanges or refunds with the Ebay dude while Madvapes has a good rep for customer service. Just sayin'......
. Panasonic, AW, Samsung the best

I had those exact batteries for a year until:
I have these Ultrafire 3000mah that I bought from a Chinese site, Dino Direct (never again). Had them for about 1 year.
The batteries were a bit longer and could not fit in to either of my two chargers. Had to place them on an angle sticking up and just barely made contact for charging.
About 80% of the time the charger would not go green and I would have to pull them out of the charger while the red LED was still lit.
The other day I pulled the batts out and one of them burned my finger and started smoking causing a blister. I immediately threw them outside over night not wanting to burn my house down while I slept.
Anyway the next day I examined the one that had been smoking and found that the circuit protection band that goes from the positive to the protection board shorted through the tape that insulates it from the body. Good thing it didn't weld together or it would have exploded.
I peeled off the wrapper and found SF US18650GR printed on the case. I Googled it and it looks like Sony/Panasonic batts rated at 2200mah. I'm thinking that the Chinese vendor soldered their own protection on to non protected batteries.

It sounds like possibly because of the way the batteries were placed in the charger (crooked) that it made contact with something that caused the short and caught the battery on fire or whatever. I did the same thing once except it wasn't while charging it was that I had the batteries hard wired from the positive and negative ends because of no tabs or holders and during connecting everything else the positive hard wire from one of the batteries got pinched over top of the other battery case and the entire part that was hard wired turned bright red and started burning through the battery case and smoking. I basically panicked and swung at the mod which luckily was enough to disconnect the short.
After reading a few of your battery posts, I strongly suggest you read the info on Battery University before you hurt yourself or someone else.
Did you bother to read any of the answers from from other battery questions? I don't think I have gotten a straight answer yet so maybe I do need to read up on battery University...lol. I joined this forum to discuss and learn about mods and batteries not to read mountains of information from Battery University.
I see....you'd rather listen to strangers on a message board instead of learning what a true expert has to say. If you want to blow up your face that's your business...just don't expose anyone else to danger. Good luck; I think you'll need it.
The battery mod forum is filled with your posts about terrible chinese batteries, whether 4x5000mah batteries for $7.89 is a good deal and rudimentary questions that have been answered 100x's over. Then you get upset at Para, someone who frequently posts great info and mods in this forum for posting exactly what you need to be doing - reading.
Please take the time to read Battery University before you set your face on fire.
Punchy, if the Battery University link is too much reading and clickthroughs, at least have a look at this sticky here, it's what 10 minutes to read?

I should have never posted about that mishap which is what it was. I am not an idiot and have been doing nothing but reading on batteries from dozens of different resources with Battery University being one of them. I always chuckle when people refer to previous posts that discuss questions people ask because do you have any idea how many millions of posts there are available to read on a forum like this? Instead of asking a possible question that has been asked before I should read through thousands of posts that pop up in a search for a similar topic to mine? That could take weeks. I know that would be more convenient for some people who have seen similar questions ask before but that should mean it is easier to answer but sometimes people just don't want to give an answer for some reason. Every place I read contradicts the next and the Battery University is sponsored by Cadex Electronics Inc. which I have never heard of so they are just as much a stranger as anyone on this forum. I am not upset about anything I just tell it like I see it is all.
