If I were to guess what killed the batteries, I'd probably say you have a single stage RV converter. I'd consider chucking that and replacing that with a three stage, or perhaps a 4-5 stage (one that can do equalization and desulfation) charger. They are not expensive, although since they bridge the gap between 120 VAC and the 12 volt side, one needs to be proficient at electrical work to install it.
