Leaf is the one that needs most replacements so far, and there are swaps and upgrades available. The fact that you can upgrade a 24kWh 2011 Leaf to a 40kWh battery makes me optimistic for the current-gen cars: by the time they need a battery replacement, we'll have better and/or cheaper batteries available for them.
