    I have an original and an aftermarket battery. I can not tell a difference in lasting power.

    I rather assume that the 'generic 2200mah NPFW50 batteries' are not actually 2200mah. The Sony NPFW50 battery is 1020mah if these batteries are 2200mah, they presumably last twice as long. I doubt that is the case although if it is please let me know.

    Just wanted to chime in with my experiance with the after market batteries.
    Of the genaric brands i went with the more known name of Vivitar.
    On initial inspection the batteries feel much lighter this was a red flag immediatly because it ment that this batttery may have smaller or fewer cells.
    I now expected the battery life to be worse, but it was just plian terrible.
    After fully charging one , i stuck it in the camera and took a coupe shots then i sat the camera down and forgot to turn it off. After one hour of non use, the battery was completely drained.

    Battery technology is improving constantly, so it isn't unreasonable that you can pack twice the mAh into the same form factor after ~4 years.

    It might well be that it needs a few complete discharge/recharge cycles before it gets its full capacity. I remember Nikon saying that in their D300s manual about the EN-EL3e batteries.

    My 2 original Sony batteries (came with Nex5 and A6000, 3 years apart) have a significant weight difference. Battery tech moves forward faster than any other tech at the mo!

    I have a couple which I have been using for about a month. That is not a long test but so far they function very much like the OEM Sony battery. I also have Wasabi batteries which also function very well.

    Just wanted to update this post and my experiance.
    The Stock Battery (1020mAh) i am now getting between 300 and 400 activations. not bad i guess this is the one that weight 2oz

    The vivitar batteries (1200mAh) range between 100 and 200 activations. these have been cycled a few times. 1.42oz

    The "Genuine" Sony NPFW50 replacement (1020mAh) 1.4oz from Best Buy that cost about $85 dollars (with tax) only averaged between 70 and 150 activations after a couple of cycles.
    I considered this to be defective and returned it.
    At first i was feeling a bit guilty for returning a used battery. But at $85 dollars, , i expect much better and view this as defective.
    ( i keep the LCD at 100% brightness. No doubt lowering it would give me better battery life ;) )

    Currently am researching this product. These run about $10 a battery
    The details state that the weight is 2.0oz not sure if that is true or even means anything.
    The Xit batteries claim to be 2300mAh
    That may result in simply a faster discharge rate and not necessarily a longer charge life.
