Having gone to a industrial grade 8 year warranty 150 amp hour Telecom surplus AGM battery that takes only 21 amps when charging, has an acid surplus, and has very thick lead plates, at 105 lbs of weight for 150 ah, you would be correct in saying I no longer need to float charge. Reason being that AGM batteries have aa very low monthly loss of charge, compared to FLA batteries.
My procedure now is to set the voltage to 14.40 V on the Meanwell, and watch the amps come down to 0.75 amp charge rate... a 0.5% rating of the battery ah capacity, and shut things down, as well as disconnect everything. I should think that 3 months of storage is fine in the winter time, I will apply a recharge the 1st of the month in the warmer 4 or 5 months here in So Cal, to stay on top of maintenance charge. If I get 8 to 10 years out of the battery, I'll consider the AGM money as money well spent. I consider the money spent buying the Mega Watt, the inline RC watt meter as something that will outlast me. If I have it go bad on me, oh well, better $55 than $155. It does exactly what I ask of it, nothing more, nothing less, no surprises.
