Meanwhile, another part of my head went in search of why Germans call 'cordless' tools 'Akku-something'... (Akkubohrer, Akkuschleifer, Akkusaege, etc).

Well, "Akkumulator" is a rechargeable battery, while "Batterie" is non-rechargeable. It's just that the English language uses the same word for both
