I have a Sony laptop and my oem battery died about a year ago. After seeing what a battery from Sony would have cost(245.00) I looked on the internet and bought a battery from
atbatt.com (135.00)
and
global-battery
(89.00) both have worked fine so far as I have cycled them
at least 20-30 times. The reason the one was more expensive then the other is because it has more capacity, though the difference is not that noticeable. Good luck
