I know there are rechargeable alkaline batteries (developed in Canada).
Rechargeable alkaline battery - Wikipedia, the free encyclopedia

However, this ad says that it can discharge ANY battery and even shows a pile of Duracell non-rechargeable batteries if you click on "Specifications" and that's gotta be false. If anyone developed a recharger that would recharge disposable alkaline batteries, it would be big news, and so far I ain't heard nuthin.
