In short, everyone would be using it if it really was impervious to 100% DOD (depth of discharge) cycles.
It seems to be just your run-of-the-mill sealed lead motorcycle battery. Basically it WILL be harmed by running it to below about 60% DOD, it just won't be AS harmed as a normal battery.
These types of batteries typically don't have the capacity to be used in EVs or hybrids. While they are certainly light compared to a normal car battery, they have a correspondingly lower capacity (EV's measure battery capacity in amp-hours, typically how many amps can be discharged for 20 hours)
Sealed lead batteries, wether they are valve-regulated, gel, or absorbed-glass-mat (AGM) have even lower capacities than traditional "Flooded" lead-acid batteries.
