Has anyone tried these battery packs ever. Supposedly ( and this is what it says on the website ) it gives about 6- 7 hours more on any laptop. More can be read about them on http://www.laptopshop.co.uk/miscpages/maxpower_batteries.htm.
you can get 9 hours on the BP3T..
Isnt the official sony battery much more expensive that the maxpower one?
you can get oem(not replacement) bp3t for about 270 shipped..
