I am new to AGM batteries and have done a lot of study prior to purchasing them as a replacement for my coach batteries. My charger has a specific algorithm for charging them when plugged into shore power so I have no concerns here.
What has been nagging me is what happens when I take off on a long (several 100 miles) drive starting out with fully charged batteries. During this drive the battery separator will deliver alternator power to the batteries for the whole drive.
Should I be concerned? Should I add a switch to disable the battery separator under these conditions?
I would appreciate any thoughts or ideas.
My only concern would be that the charging voltage of the vehicle voltage regulator may be set at a higher voltage for conventional lead/acid batteries. This could lead to possible over charging.
