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

When I perform a capacity test I zero my trimetric AH.. I have 2 agm's 100ah each.
200 ah discharge at c/20 down to 70% which is 60ah...
I then measure battery voyage after a rest period of about 2 hrs.
I do take into consideration the temp of my batteries when performing this diagnostic.
Realize that AGM's voltages v/s depth of discharge is different. AGM's are higher by .1-.2vdc.
That's the way I determine the health of my batteries.... FWC or AGM.
Also, I track ah removed daily. I measure early morning voltage v/s ah's removed. I can see when things are not right... Always performed this....
