You looked wrong. These batteries can do 100,000 charge-discharge cycles while retaining 80% of their capacity.

- willismichael 2mo agoIt really depends on the battery chemistry of the specific EV, how many watts you charge at, and deep cycle vs. shallow cycle. Not all EV batteries will hold up to that many charge-discharge cycles. Even at that, 100,000 cycles is an exaggeration. From what I can tell, you can expect up to 3000 cycles from Nickel Manganese Cobalt batteries before they hit 80% of original capacity. Lithium Iron Phosphate batteries can last for 10,000 cycles before dropping to 80% of original capacity. https://bslbatt.com/blogs/lfp-vs-nmc-lithium-battery-comparison/ https://bslbatt.com/blogs/lfp-vs-nmc-lithium-battery-compari...
- toasty228 2mo agoHm sorry but no, feel free to read the specs of any manufacturer, they're rated for a few thousands cycles at best, usually under 5k, closer to 2k Even lifepo4 home storage batteries designed for frequent cycling are rated for ~10k cycles. As far as I can tell there are literally no battery chemistry that can survive 100k cycles and retain 80% capacity
- dyauspitr 2mo agoYeah, I have no idea where I came up with that from. It’s completely wrong.
- toasty228 2mo agoYou might have read 100 000 miles? They do last a long time when used for their purpose (driving), statistically you'll get a gas engine failure earlier than a battery failure. But they're not made for at home day to day energy storage
