So I bought 2 packs of 2 batteries. First off, as most reviewers have noted, these can't be 4000mAh. And certainly at $5 each. I load tested all four batteries down to 3V.. The results were 1733, 1729, 1747 and 1436mAh (I'll retest the latter just to check). The weight of the each of them was approximately 44.5g. They are oversized because of their "protection" so they may not fit in some applications

  • MarcBohets Strange that you still give 4 starts, when the capacity is not even half of the rated capacity, in this case only 1 star would be more appropriate.

  • beakyboy @MarcBohets price versus performance. at less than $4 each - that's a lot of storage.

  • wowi55 @MarcBohets i fully agree, 1 star!
    they keep testing with how much they get away with. some are labelling 6000mA, what next? 1,000,000 mAh gold-plated?
