Replacement battery for original Sony item in a recent purchased 2nd hand Vaio Duo 11 SVD*******PGB. It's getting harder to find batteries for Duo 11's, as Sony discontinued them several years ago.
This replacement is not original but fitted perfectly, once I got past all the screws holding the base directly over the battery. A BIG thumbs-up to Sony for making it relatively simple to replace the battery!
Good price, quick delivery.
