Battery replacement

[Ron W]

Have a 2012 Interstate, one bad house battery should I replace both?

Also suggestions on replacement for Triplite inverter.

Welcome Ron,
It doesn't matter if it's a flashlight or an RV, if it has two or more, replace them all.
As for your question about replacing the Tripplite, that's outside my knowledge but the Forum has lots of threads on the subject; check them out. The gist is, replace the Tripplite with the newer, more capable Magnum. It's quite possible the Tripplite's high float voltage fried your batteries.
All the best, Dave the Scourge of the ION

Thanks Dave! Any recommendations on what to use?

Yep! 2 new Lifelines and a Magnum MMS-1012 1000 watt sine wave inverter/charger with temperature sensor and their ME-RC programmable controller will solve your battery problems.
