I bought four sets of these direct from 7DayShop. I buy quite a few things from 7Dayshop and find them to be good value and excellent products, generally.
However these batteries do not seem to be up to par. The good thing is - they come in a nifty little plastic box which is very, very useful for organising your batteries, particularly for my purpose - that of off-camera flash.
However, I put four of them in a Maha Powerex C-9000 charger, in "analyze" mode, at 500 mA charge, and 300 mA discharge, and they were all reported as being around 2000 mAH, which is just over a third less than their stated capacity. Now not everyone has a sophisticated charger - so not everyone will be able to test the capacities of their batteries.
A second set I am currently testing, one of the batteries has already terminated at just over 1000 mAH!
Now - I'm being generous and giving this 2 stars, particularly as even at 2000 mAH these batteries would be good value for money, and I havent tested them all yet, but from this evidence I would say these batteries need to be viewed with caution, particularly if you really need that higher capacity (such as those into radio-control etc.)
