Test/review of LG 18650 HG2 3000mAh (Brown)

I have to dig this out because of reasons.
I read somewhere, that the HG2 age pretty badly and that they lose capacity fairly fast compared to the 30Q.

Since GB offers them for €14.02 I would like to know if this is true or not.

I would use them in the Utorch UT03 so I need some good High Current Cells
