Some of the mediocre large prismatic ancient Chinese 1st Gen lithium are functional albeit degraded at nearly 20 years old

Sure might have dropped a few cells but hobbiests just wire over them.

In power walls Chevy Volt packs will likely have outliers go beyond 20 years
1st Gen Volt Design life being 15 years means you will a non insignificant portion make it to middle age in a power wall scenario
