LiFePO4 batteries generally sit upwards of 3000-8000 cycles to 80 percent original charge.... Depends on what your chemistry is. As the batteries improve, you'll probably want to upgrade every 8-10 years or add/swap out a 1/4 to 1/2 storage by that time, still able to use effectively even if a little lower top end. Depends on your usage and if you're still on grid.
