Excellent for the price,
Verified Purchase(What is this?)
This review is from: Ex-Pro Sony NP-FW50, NPFW50 High Power Plus+ - 2 Year Warranty Replacment Sony Lithium Li-on Digital Camera Battery (Electronics)
I have not noticed a big difference in battery life between this and the original Sony battery (which for a Sony product I would not decribe as brilliant). I now have 3 batteries for my SLT-A55 and do not know which is in the camera from the amount of battery life I get. I got 2 non Sony batteries for less than the cost of one original, there are cheaper ones around but these seem pretty good and work fine.
