I have heard conflicting stories on whether to have a AGM Battery tender or not. If the hummer is sitting for a while should I hook up an AGM battery Tender to it? @Tom E-Tron Tom, your thoughts?

Once the vehicle reaches your predetermined SOC (ex 85%) the charger shuts off, so how will it keep maintain the 12 volt battery?

That was my concern.... I keep mine at 80% and it clicks off. Unless it turns on to monitor somehow?
