I get about 4.5 to 5hr of usage from this battery after each charge. Because of the battery's larger size, it adds about one inch to the notebook. I have to use a much bigger notebook sleeve. As another reviewer mentioned, its shape does look weired, adding depth as well as thickness to the notebook. But the plus side is that it rises the notebook and improves air circulation underneath, making notebook a little less hotter. The price is very high.

I got my battery free when I sent my SZ notebook to sony for repair. the battery does last much longer than standard battery. The only problem with it is that the shape of it makes the notebook harder to store. I tried to put it in one of my notebook cases filling with other stuff, but it just hard to get the notebook fit in there.

Great battery overall. The life of the battery after one charge lasts approximately 4 hours. Its price is kind of high, but overall you get what you pay for. It is a good investment. I will buy another one once this one goes out.
