I don't know the actual numbers on that, but I do know that stationary storage lasts much longer than e.g. EV batteries, since there are no weight restrictions, so they're cycled more gently, temps are better, they can be kept in a more optimal window, you can use things like LFP that are heavier, and BMS has more latitude with more cells to work with.
