[quote=Anonymous][quote=Anonymous][quote=Anonymous]It is very rare that EVs need a battery replacement— the idea that it will happen to every EV at the 10 year mark or whatever is FUD[/quote]
Ok, you win. Not EVERY ev will require a new battery at the 10 year mark. [/quote]

This has been the experience with Nissan LEAFs unfortunately.  But they have poor battery tech and no heat pumps to handle the temp changes.  Small batteries that eventually dropped from 100 miles a day of use down to 40ish after 10 years.  So, most had to retire them rather than get new batteries.

Newer lithium ion and iron phosphate batters have better conditioning systems so seem to last longer.  Even with reduced capacity dropping from 200 miles to 100 still makes them useful as commuter cars.  Instead of changing the whole battery you can change out the individual packs.  Still costly at $1500 a pack, but better than replacing the whole battery.   This business has not taken off though.  For one it voids the manufacturer warranty.  But more interestingly is that because batteries are more reliable there are very few that have been able to taken out of old cars for reuse. [/quote]
