I'm currently contemplating upgrading my 2013 Leaf battery to a 62Kwh (and much longer range). It's a substantial cost but that would extend the cars life another 15 years. (un)Fortunately I've taken decent care of the original 24Kwh which is at 80.6 SoH after 11 years. Its use case is daily commuter under 45 miles - that's over 11k miles/year (or 18k km/year). At 2% loss on the SoH, that's another 5 years before it hit's 70% and has a noticeable drop in range.
