Yes inadequate charging is deadly for the AGMs in our cars. I never use the ECO system (always tap that button!). Interesting tidbit about the 75% soc limit ... good thing the Ctek keeps mine high between trips. And those short trips are the ones which harm the battery ... hardly have any charging activity due engine loads.
My battery is still fine after almost five years. I also push the ECO button upon starting the car. I haven't worn out my finger yet!

It's the young'uns playing their music too loud in the car that drains the battery a lot quicker than it ought to...
