Note that AGM batteries do not normally have any liquid electrolyte, and adding water would almost never be a good idea.
I think you got good advice to contact the manufacturer.
Good luck, and I would like to know what you find out.
How far do you normally discharge your battery bank? - only once to 11,8 in 5 years
How was/is the battery bank monitored for depth of discharge? - no monitoring: the inverters never cut-out due to deep discharge until the said batt. went dead.
Thanks in advance,
here are facts on AGM: Absorbed Glass Matte or "AGM" batteries are the latest and greatest in lead-acid batteries. An AGM battery uses a separator consisting of fiberglass between the plate and wrappers to hold the electrolyte in its place with capillary action. Combining the lead plates, electrolyte, and fiber glass separation fibers in a confined space, AGM batteries create a "physical bond" by way of capillary action. Similar to how water creeps up a towel when it is put in a bathtub. This capillary action holds the liquid inside the glass matting, making the AGM Battery "spill proof" if it is ever exposed.
Now, surely the matte cannot hold unlimited qty. of liquid, so I guess my question remains. Thank you.
