Testing AGM Battery capacity?
With the help of a good electrician it appears I've finally worked out the bugs on the PO's battery upgrade on SOLARE. (4 group 27 = 440 amp hours)
He and the Link 20 manual say to do a battery condition test, to run 5% or your capacity until you get a 10.5 voltage reading. Then you can determine what your real available capacity is.
But, somewhere I recall reading that AGM's don't like to be fully discharged, and by doing so I'm shorting both the life and capacity.
Is this a good thing to do, or is there a safer way to determine actual capacity?
