3000 cycles “lifespan” but most of the degradation happens in the first couple of years with the rate of degradation about 3% a year, capacity still remains and the product will still have significant capacity in 20 years. As opposed to say a synchronous converter which requires annual downtime and continual replacement of parts, and (being limited by inertia) can’t provide the same stability and support that a battery can.
