The battery provides about 3 and 1/2 hours of power and charges very quickly. If you have one of the older Sony laptops and are looking to replace the battery I would recommend buying this one.
I was very happy with this product, and it was cheaper than the OEM batteries and it works well.
I just received and it seems fine. I purchased on the basis of the comments here and I am not sorry. My first charge calculated to more than four hours. So far, so good.
This is an excellent battery replacement. This is the 3rd replacement battery for my sony. It is replacing two others that failed right away. I am very happy with how quickly I got this battery as well as the quality. I recommend this battery over any other on this site. Also it comes with a one year warranty.
