Hi everyone - My cranking battery died and I'm looking at an Optima Blue Top AGM. If I go AGM can I continue to use the onboard Real Pro Charger (RS3) to charge all three as I do now? I thought I heard somewhere that you are not supposed to "mix" AGM and Wet charging. Real Pro's site says "There are no mounting restrictions requirements with Dual Pro Chargers. Use with Flooded Wet Cell or AGM batteries.". Unclear to me if both typed can be hooked up at the same while charging. TIA!
