Speaking of internal shorts, the AGM, with everything held in place
with the glass mat should be far less likely to short than the wet
cell where chunks can fall off the plates and there is only liquid to
keep them from moving around.
I would agree. Not just chunks but in an aging and poorly maintained
battery a constgant rain of debris to the bottom of the case where it
eventually shorts out the plates when a heavy load is applied. Our
problem was no-name batteries to begin with which the yard failed to
maintain over a long in-water layup. The following March when moving the
boat I advanced the throttle from slow to WOT and BLAM!
