It has Sony's name on it. And it was a huge improvement over my 3 year old battery.

It seems to be, (I cannot tell the difference from a good fake product) but the life curve does not appear to be so good as that of the original one.

My Vaio didnt accept it. Vaio specifically says "non OEM battery. Please replace". Couldnt get it to work.

It is not a genuine Sony battery but after 5 months works good on my Sony VAIO E series computer.

I believe the battery is a genuine Panasonic battery. I matched the original battery with the one bought I bought in aftermarket. Both batteries are the same. Both batteries function the same. The duration of charge and the camera readings are the same.

the ad says "Sony AC L200" and it also says "by Sony", and one of the reviewers says "Good OEM product", and another says "the power supply is an original Sony part..." Yes.

I ordered it for myself but it was the wrong product. I have a Sony camera, but this one is for Sony camcorder. It's an original Sony battery not refurbished. It came in an original package, but it had been opened. It looks "brand new" or at least "like new" to me. I don't remember the name of the seller. Hope my answer is helpful.

The NP-FM50 I ordered is the real thing. They say Sony right on the battery.

We are sending both batteries. the original Sony battery is still included in the box.

It's an additional battery, however, I was disappointed when I realized that the battery is their brand "focus," not a Sony brand battery as pictured. The Sony camera case is not what I would describe as semi-hard and it's also not as pictured.

I sincerely believe this is a counterfeit Sony battery. After an overnight charge it provides about 50% of it's advertised charge. I do not recommend this item be purchased by anyone.

Neither. The battery pictured is not branded or has been scrubbed clean. The original battery is branded Sony and the second battery is branded Vivitar. The Vivitar comes in its original unopened package.

It appears to be an original battery. The battery life is similar to the original but I can't speak for it's lifespan yet. Hope this helps.
