Battery OEM Nissan or OEM BMW

After several tests they were able to get the battery fail code they were looking for. Nissan replaced the battery with a new one, and so far so good.

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.

I'm in central Texas and the Leaf does just fine for in city driving. The batteries run hotter than a liquid cooled battery does of course but they are capable of operating at Texas summer temperatures. Where they struggle is on long highway trips. High speeds mean more load on the battery which also means more heat and more likely to have the car limit power due to battery temps. I have noticed that Leafs in Texas do tend to show more battery degradation and less capacity than leafs that are in cooler climate.

I have a 2015 Nissan LEAF SV. In -25C or colder (and to be fair, it's rarely -25C (not counting the windchill) during the day), with moderate heat on (set heat to 19C or less) plus heated steering wheel and heated seats (both of which use relatively very little power), I can lose a good 60% of my range

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.

Problem I have with my 2016 is I go threw lot of batterys , first one lasted 3 years which told it comes with 3 year battery 2 one lasted 2 years ,The third one only one year..So brought to dealer. They checked connections and hooked up meter left hooked up for 2 days..It draws .07 amps when just sitting.
