AGM batteries
Hello, wondering if AGM batteries should be equalized monthly as normal wet cell batteries are. Thinking of changing to AGM. Thanks Socal

This is why with AGM accumulators it is so important to use an amp hour meter and document new battery performance (state of charge vs voltage). To be compared later on with subsequent readings if you suspect the battery is playing hooky.
The only way to tell if the 1.300 specific gravity soaked glass mats are getting "uneven" is to get out your Skil Saw. So the term "equalize" is not used with a valve regulated battery. Intelligent manufacturers might label it "conditioning" the term I chose. It is done SOLELY after instrument readings verify the battery needs attention. You don't go to the doctor once a month to get a needle stuck in your butt for the hell of it. The same theory applies to treatment and maintenance of a valve regulated and flooded battery.
"Gee when the batteries were new I could discharge them 95 amps hours and have 12.54 volts showing on the amp hour meter. Now when I discharge them 95 amp hours the voltage is only 12.42".
Your brain just told you what no multi-thousand dollar Plug N Play system ever could or ever will in your lifetime. You have a problem and have a metering system that tells you when you (with an agonized moan) rise out of your recliner and decide to do something about it AND YOUR FIX WORKED.
