... But: The battery (ordered from "Werkzeugalarm.de") is actually part of a bundle (charger and two batteries). The bundle is naturally cheaper than the individual components - is separated from the dealer - sold separately - and thus a low price is possible. Do not misunderstand: I'm very satisfied with the dealer - the delivery was very quick - the packaging was perfect (not original Bosch Packaging - of course ... see above).
With a "trick" I could register the battery even with Bosch online - for service / warranty.
Whether all this is then also regulated under warranty so super as Bosch "blue" usual ... I do not know.
Nevertheless - the price is good - the dealer showed very good performance - everything else is pure speculation.
