They've been 'up and coming' since I was youngbut I think the up and coming Sodium Ion batteries will be enough better than SLA and enough cheaper than Lithium to have a chance to take over the field.)
Of course they are fine for UPSes as the low energy density per unit weight isn't a problem, but UPSes aren't a large enough market to drive up volumes and hence drive down costs.
