Finally, the replacement battery (VGP-BPS2C) for my Vaio VGN-C1S/H arrived (8 month after I reported the defect).
Sony advertises the laptop with full 2 year guarantee; however, the guarantee does not cover consumable material which, in Sony's option, includes rechargeable batteries (as one learns from the guarantee statement inside the package; the Austria Sony website nevertheless has different terms and acknowledges guarantee for the rechargeable battery). Only within the first six month after purchase, the manufacturer is assumed to have supplied a product with manufacturing defects, the onus of proof reverses afterwards. Sony declined to replace the battery under warranty.
Thanks to Verein für Konsumenteninformation (VKI) for intervening successfully!
