Until you know how your battery/converter-charger function as a unit, be sure to include weekly battery electrolyte checks. Nearly all "maintenance free" batteries are not "maintenance free" but are "maintenance reduced".... Nearly all deep cycle and marine/RV batteries have "not easy to remove" battery caps, but they are removable and you do need to check the water level. Don't be "lulled" into believing that your "maintenance free" battery can be ignored for weeks or months while connected to the converter-charger in your RV. If anything "goes slightly off center" you can destroy your new battery before the end of the camping season just from letting it sit ignored on the tongue of your trailer.
