while searching eBay for 18650s i came across this seller in the UK
he seems to test what he sells and give a good account of the good and bad
this is his web site http://www.torchythebatteryboy.com/p/batteries_21.html i have no connection with this seller other than i have ordered some batteries from him
i emailed and have his permission to post this link
cheers Barrie
Thats a great find Scruffy. There's nothing better than a meticulous seller thats also an enthusiast. This guy is obviously a battery-a-holic. Wouldnt you agree Old? 
Great site. A lot of info! Thanks for the link scruffy.
GJ looks like panasonic is a winner
wonder who makes xtar and senybor , cant find them for sale here ( US)
thx for the info
Yezl 2400 and Trustfire 3000 actually looks good. Surprise surprise....
