So far, I can only find Duralast batteries online, and I wanted to know if there was any other brand that someone can recommend. I live in Michigan so the winters get very cold, and I don't daily my 545i anymore so I'm looking for a tough battery that will last a while.
Just replaced my AGM battery and did some comparison but in the end it came down to one having a 3 yr warranty and another with a 6 yr warranty similar price so it was a no brainer for me Canadian Tire in my case. Most if not all are made by or for Johnson Controls anyway....

I use a solar panel (5 watts) wired to the boost attachments in the engine compartment. At least the battery is "tended" during the day (which is enough even for long periods) and there is nothing to plug in.
