I'm no expert, but in my experience the costs are pretty similar and you know the OE battery was made to support the stock electronics in a variety of climates. I guess if you wanna save $20. Terra seems to be the most believable poster in the thread, I'll take the smaller and lighter stock battery

The actual factory battery, which most of us have likely replaced by now, was made by Varta. BMW Dealers in the US mostly stock Exide manufactured batteries. Sometimes East Penn (Deka).

Bosch batteries are rebranded Exide (at least the AGM ones).

I'm running a Bosch H8 AGM in my car right now. Generally I think Deka would be my preferred brand (haven't had a problem with either, but Deka seems to carry a better reputation), but I needed a battery urgently when I most recently replaced mine. Both fit perfectly in my battery tray.

Lately I’ve been seeing these “Champion” AGM batteries at PepBoys and those are priced better than Bosch AGM with the promotions. As an example, the H7 AGM is currently at 157 while the Bosch one is at 192.

Has anyone used the Champion brand? Who is the manufacturer of these AGM batteries?

Googling seems to suggest Champion is made by Johnson controls. The Bosch's are Exide. Either should be fine.
