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

What we don't need is multiple definitions of equalize.

You can also define "equalize" as being an extended time at the "finish" voltage without it being at a higher voltage than that.

You can have capacity loss from incomplete recharges while all cells remain equal. You would still need to condition your AGM even though it did not need equalizing. (You can't use an hydrometer to spot unequal cells anyway)
You would have to notice the capacity loss somehow. Say a mis-match between AHs from "full" vs morning voltage on the Trimetric, or a shorter than usual time to do a recharge.
Edit- I see Mex beat me to it. :) Grasshopper still not fast enough.

It had just crossed my mind - Deka has some manuals that relate to both AGM and gel. Did they specifically mentioned AGM for that equalizing voltage?
