When Lifeline recently explained to me about drying out their AGM batteries prematurely, I knew that they were referring to hydrogen and oxygen slowly escaping out of the one-way valves due to float voltage being too high such that the recombination process can't absorb the hydrogen and oxygen from the float voltage electrolysis of water fast enough. Hence the hydrogen and oxygen pressure builds until some irreplacable H2O (hydrogen and oxygen) leaks out of the one-way valves.
My issue when recently shopping for new AGM RV batteries was: At what float voltage does this begin to happen for any specific brand of AGM battery?
The release pressure of their one-way valves can be adjusted by AGM battery manufacturers - based on the recombination rate of their battery design. This may be related to why manufacturers can and do specify different float voltages (at any given temperature).
