FYI: Unfortunately throwing new parts at it without a legit reason seldom works. Either your electrical system is physically up to spec and you follow the OEM recommendations or not... regardless how you’ve been operating the aircraft. Even installing a new battery not in accordance with the OEM recommendations can start you off on the wrong footing. And considering you only got 18 months out of your last battery, I’d say you have one or more issues with your electrical system and/or how you maintain that battery. This is the same thing I’ve told many owners on my side with similar results. But its your money. Best of luck.
