(was Re: Disc analyser news update) Batteries have advanced since your laptop was originally made. Aftermarket batteries use newer cells which seem to last longer (amphours). If the voltage is different or the battery is not an exact fit then I would be worried, but not if the rated amphours is more then the old battery. As others have said all batteries are made in China these days, even OEM ones. Sure there are bad ones out there with marginal cells, but that is the case will all of them. Aftermarket batteries seem to have cheaper electronics inside (some of them anyway). There is a place out in California that will recell your old battery for $55 or so with free shipping if you don't mind it looking a little frankenish (they are welded shut and need cut open and then resealed). Like anything else there are only a few companies making the actual cells anymore (Panasonic and Sanyo come to mind) so you do not have that much choice in quality.
