Battery Bosch or OEM BMW
Yuasa are high quality. I generally get Bosch S4 or S5 as they've never let me down.
Regardless, while that’s sorta old for a battery, I have OEM BMW batteries going on 12 years with 89% charge capacity.
And yet my 2008 VW had a Bosch battery out the factory ????♂️.
Fucking thing lasted 10 years or so though. So credit to Bosch for that one!
I've had good luck with Bosch (made by Varta iirc) and Yuasa.
These were very very well made batteries. They also used to be insanely expensive. Now, BMW knows the game and offers a 2 year warranty, which is pretty low for batteries, but they are very competitively priced.
My 2021 45e usually gets 30-34 in mild southern US weather per charge.
I drive a 2016 f15 x5 40e. After 7 years i still do the same distance full electric, maybe 2-3km less but can be my driving style
There is a known random issue with 400 packs. On mine, it is always when I turn on the bike. The speedometer doesn't come on and there is no assist. What I learned about on the internet is to push the test button on the battery with the bike turned on and it will reset and work just fine.
I find that the Bosch batteries I regularly sell last 5-7 years or 5-7 months.
530e with a little over 20,000 miles shows 10 miles electric range on a nice summer day. It used to show 15 when new. BMW said that the drop was not warranty worthy.
