They are used telecom batteries so are a variant of AGM but are not a starved acid configuration. The are Dynasty UPS12-490MR
The chemistry is Lead Calcium AGM with a SG of 1.300
PT, just for education, not questioning anything! Those specs for your UPS batteries seem at odds with the table at the end of this blurb.

Also how did you get the SG of an AGM???? (1.3 seems way high for a UPS wrt the blurb above too?
