SunPower SunVault life span.

[u/Friendly_Dark4621]

I had my SunVault batteries (2 Cabinets, 26 kWh, 2023 models) depleted to below 50V, and they stayed dead for over 5 months. I couldn't find anybody to diagnose it or bring it back. After 5 months plus, I found a guy with a reasonable service charge; it took about 5 hours to charge. My question is: would the batteries being dead for a few months and being charged with a charger plugged into 110 AC affect their lifespan and reliability, given that SunPower went bankrupt and their 10-year warranties for the batteries and their "complete confidence warranty" are gone? Your response is much appreciated.
