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.
Yeah, the oem Panasonic battery is easy to kill. I replaced mine (2022 Turbo) with an AGM type. Most all batteries are made by Johnson Controls, under different names. The cheapest price I found was $179 with a 4 year warranty at Walmart. Everstart Platinum group 35. Was a 10 min job to remove and replace. They can even test your old one. The agm type is in the deep cycle family, it can be discharged quite a bit without any issues, the stock battery (flooded acid type) is easy to damage.
My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.
I just replaced the battery on my eco drive from maybe 2008ish? Battery itself was 14 bucks on ebay, oem brand(Panasonic). Swap took 5 minutes.
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 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.
Yes. Mine was from 2020 and quit without warning March of this year. Contrary to what some people have said, the car won\u2019t always warn you that the battery is weak.
Yes, my 2021 battery died mid 2024. No warnings, no abnormal behaviour. Luckily it was still under warranty and the towing and repairing were free.
