Recommended Battery Charger for 4 AGM RV Batteries

Question:

I have a 5th wheel toyhauler. I use 4 12 volt AGM Trojan batteries. It has a master shut off switch. All the batteries are connected together. It is difficult to disconnect all of them. Which single battery tender would work best for use while storing my trailer outdoors in the winter? Thank You

The battery charger is best selected based on the size of the battery bank and battery type. The OptiMate 7 Smart Battery Charger part # MA37JR can charge/maintain a bank up to 400 amp hours. It works with flooded, AGM, gel, Ca-Ca (lead calcium), and deep cycle batteries. The two ring terminals will simply be attached to the last battery so you don't have to unhook each one. It will work with both parallel and series wiring.
