Much more stable chemistry. In stationary applications, like UPS systems and off grid electrical systems, lead acid is still the standard, due to having stable chemistry, very unlikely to catch fire, and a cost to capacity ratio that is still very good.
The degradation seems pretty bad, but if it’s stable from 300 cycles onwards, you could take 75% as the actual capacity of the battery.
