Battery OEM BMW or OEM Volkswagen
I replaced the battery of my 18 SE this year and did not code the battery. I replaced it with an OEM one from VW’s parts department and had no issues
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
I have been driving a 2022 330e since March 2022 and haven’t seen any battery degradation to date. In the NY winter I still get at least 20 miles on a full charge, in the summer 23-30.
I set off to test the X5 battery to see if degradation was better or worse than my iPhone's 10% degradation over one year. We've driven 29,996 miles, 15,296.5 electric. My best all-electric range achieved was about 41 miles when new. After one year, I achieved exactly 41 all-electric miles from a full charge in ideal conditions. Zero percent degradation as measured by this test. It appears temperature and AC/heat use have much greater impacts on range than actual battery health at this stage. Results look better than expected for long term ownership and residual value.
Had my '18 R since May '18 and still on original battery, 25 mile commute to work each way about 1/2 hwy . At 57,000 miles.
Battery died July 2022. So got 3 years out of it. New battery is AGM (OEM VW from dealer). Stock battery was not AGM.
Since the battery weighs ~40 lbs this isn't really a significant weight change from front to rear so I've no idea if the car handles any differently. Would I recommend this mod? Probably not as it's not cheap and has no real performance advantage and more crazy than anything.
On the other end of the spectrum, the eGolf sucks. It wasn’t good when new and I can’t imagine spending that kind of money to repair it.
