Battery OEM Honda or OEM BMW

I’d take a Honda battery over a Subaru one any day if the week.

It had a Honda battery in my Subaru for years

Honda batteries (at least the normal-sized ones, not so much the little 151R's) are honestly pretty solid.

For about a month I have owned a 2016 REx whose 60 Ah battery is supposed to get 72 miles. This week I fully charged it and have been commuting four four days without topping up. Today the REx kicked in with the trip meter at 73.3 miles. This was a mixture of city traffic jams and short bursts on the carriageway, mostly with the air con on and mostly in Comfort mode. So I'm pretty pleased.

I am still on my original battery in my 2007 335i w/ 87k miles.
