lead calcium agm non starved acid battery
Hi all, I have: Dynasty UPS12-490MR The chemistry is Lead Calcium AGM with a SG of 1.300 Amp-hour capacity 139.2 when new. They are a non starved acid AGM. I have four in two balanc...

Reduces conductivity (increases impedance significantly). Reduces incidental micro gassing which because of recombinant technology is extremely difficult to detect. The entire operational voltage profile is raised as much as one to two tenths of a volt.
By the way ALL absorbed glass mat batteries contain varying amounts of calcium in the negative plates. What I mused is increasing the calcium content, not merely introducing it.
Concorde chose silver to augment calcium in the negative plates. A measurable reduction in impedance therefore increase in conductivity.
Thicker glass mats are far and away the most significant modification to a standby battery. That and extremely thick plates to offset a higher erosion factor due to 1.300 electrolyte.
Those batteries are engineered for prolonged life in standby mode with safeties built into battery maintenance mechanisms not in the inherent design of the battery itself. Total prolonged discharge will damage this type of battery a lot more than an acid starved type.
Your personal experimentation to establish trends and tendencies will reward you 100 times better than asking mere questions. Find out exactly where the .5% point lives. Do an estimated 50% amp hour capacity extraction, mark a voltage baseline then recharge to establish a custom for you only Charge Efficiency Factor. Perform an amp hour accumulation test at 13.2, 13.4 and 13.6 volt float value. Load test the batteries. Max inverter. Test the batteries individually for voltage equality.
Discovery is fun and semi-permanent.
