Battery OEM Toyota or OEM BMW

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.

The price on a brand new Toyota OEM battery for the 2019 SE nightshade edition is 445$ish about 500$ after taxes. It’s designed for the stop start in the vehicle, it’s also backed by a 84 month warranty so you’ll never have to pay for a new battery for 84 months. When it comes to the battery, I would always go with OEM and have a good warranty on that battery as I do not want to deal with having to shell out another 200-300 dumpster autozone battery that has 3 year warranty or less.

Only thing I've added is a dash cam and all-weather mats. 26k miles with the fuel sender recall completed and a dead battery that is a known issue otherwise no issues.

My battery in my Toyota echo is from Toyota and it’s like 12 years old and still starting at -35C so I’d say go with Toyota genuine

I have a 10+ year old Prius C that had a 100k-mile warranty on the battery. It failed at 108k and cost $4k to replace. It's at 230k miles now, and I expect to have to replace it again (but who knows?)

my bmw would say this, a year after having a new oem batt installed, and only in the winter, dealer couldn't find the problem, so I traded it in for another subaru because parasitic draws are the last thing you want in a german car
