Q&A—Are Battery Desulphators a Good Idea?

41kZZ2EyAPLQuestion

From member Conner:

I was wondering if there is any instance or reason you are aware of where a continuous battery maintainer/desulphator would be bad for AGM batteries? Unfortunately we live on shore power a lot right now, and I wanted to buy a maintainer for our AGM starting batteries to live on, such as this one. [A combined desulphator and charger.]

The distributor said I did not need it, and actually said to not get it. Do you know of any reason why a maintainer/desulphater for AGM batteries, hooked up full time to AGMs, would be harmful? (Full River AGM batteries)
