Battery Tesla or OEM BMW

If I could easily repurpose the cells in my 140k mile Model 3 into home storage for my solar I would rather do that than sell the car. 3% degradation the car itself needed more work than a replacement battery ever would have cost.

I’ve had my iX for 2.5 years and have logged 122k miles. I haven’t noticed any degradation in battery capacity. Just the normal summer/winter fluctuations (live in Midwest).

I had one with the battery that lasted just under 12 years.... Old original BMW batteries are built different! Especially if the car is driven regularly.

Tesla on nmc battery drops around 10% after 8 or 10 years (can't remember exactly) from what I read. But lfp battery is inherently able to have longer life span and charge cycles. On top of inherently having ability to be safer / less explodey.

For context, I have a first generation Tesla Model S - 2014. It has 215,000-ish miles on it. The battery capacity has gone down by about 10-12%. It still runs and drives like a dream. It's on the original battery.

I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.

I have an early VIN 2020 MYP with 80,000 km; the diagnostic says 87%, so 13% drop in battery health. Range calculation at 100% SOC dropped 4.9%.

I don't want someone else's crusty ass battery. Charge times are already low and are plentiful (Tesla at least), I don't see the utility of swapping the battery out when I could stop for like 15 mins.

2019 model 3 SR with 10% loss based on full charge at 52k miles.

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.
