I have found a used battery for the Bosch eBike system online. Can I use it?
When purchasing used batteries, always make sure that they have not been damaged by their previous owner. Damaged batteries are occasionally available online but they pose a significant risk and can lead to dangerous malfunctions. Sometimes illegal or stolen goods are available online as well. If applicable, ownership of such goods cannot be acquired legally in accordance with § 935 BGB [Bürgerliches Gesetzbuch, German civil code].
