Very good battery at low price! – UltraFire Protected 18650 3.7V 2400mAh Lithium Batteries (2-Pack Grey) Reviews

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
The exact voltage: I've bought 4 batteries, 3 of them showed 4.23 volts, one showed 4.26
So I think it's a good precision.
The build quality is perfect! It looks not like on the image - the text and color scheme a bit different, but I've received a better than shown on general photo - the anod seems to be copper.
I really didn't expect such a quality for this low price.
Cons:
None
Other:
Bottomline:
I bought it with P7-based torch... Full discharge at lowest brightness takes 3.5 hours. I've also tested it at maximum power (~12W), battery itself doesn't heat at all. Must buy.
