After experiencing very short life with the last battery in my sony laptop , I decided to try the new battery. I don't carry the laptop around on a daily basis so weight was not a major issue for me. The new battery is giving me about 3 hours of service, a big improvement over the last one.i am very satisfied with this deal. highly recommended.

For those who are worried that they are buying "generic" batteries, worry not/it is reliable. the products wirks well in my laptop. appreicated.

The battery worked well directly out of the package. Recharging time is commensurate with my original one.

this new battery brought new life to my sony laptop.i like ikt very much,wish it couldkeep this working situation.
