I have an 08 e92 and the batteries starting to go... slow clock.

Well Tischer sells the battery for 215$ but can't ship it because it's considered hazardous material. What are my other options?

And can someone please explain to me how the new battery needs to be "registered to the car"? I understand there is a tool to do it yourself, but would it be cheaper to just have the dealer do that? Could someone send me a link of where to buy this tool?

Thanks!
