Battery OEM Toyota or Tesla

After 16 years and 140k miles, our Prius battery is still going strong.

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 bought mine last year 2016 SR5 4WD at 116k miles. I'm at 140k today and it feels like new. I only had to swap the battery because I forgot to check how recent it was when I bought it.

My neighbor bought a Prius 15 years ago,whoever they came out, the dealer told him it would cost $5000 for a new battery replacement. It lasted until 2024, it cost $1500 to have new battery put in,aftermarket of course

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 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?)

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.

battery life is astonishingly unpredictable. I drove 20 miles, but lost ~35 miles of range. Not driving crazy, either. Everything else is decent, but can't help but feel like it's a time bomb.

Having been burned with low quality auto parts store batteries (specifically for the Prius) and their being unable to honor their warranties, the Toyota battery is the only way to go.
