RV Deep Cycle Battery

I'd consider replacing your old-technology lead-acid with a more modern AGM lead-acid version. They cost more, but have longer lifespans since they're all but impervious to vibration and shock, and have many advantages over regular batteries. They are the first choice for aviation and military applications where rugged long-life batteries that can be rapidly charged, discharged lower safely, mounted in any position, don't require a container, don't degas or ruin your jeans, battery tray or washer pump, and can be used indoors safely, etc. etc. I went with one instead of bigger, heavier, cheaper lead-acid marine battery and have decided I'm not going back to the standard batteries. :C
