Good old lead acid is still quite popular in off grid and UPS systems, it's still quite cost effective if size and weight isn't much of an issue.
Yes, but with a limited cycle life of typically 300 or so for AGM, significantly reduced if the battery is ever more than 50% discharged. Also high losses in charging, and needing an extended duration of high voltage low current charging to get to 100% from 80%
For larger applications you don't use agm, you often go back to flooded batteries with even replaceable, high cycle cqthodes: https://www.sciencedirect.com/science/article/abs/pii/B9781782420132000030
