When I purchased my Lifeline AGM's from Lifeline in California, I asked this question, "Do your batteries need to be equalized" and contrary to what others have said here, the answer was YES. Our AGM's need to be equalized but most other brand AGM's don't.
As a matter of fact, when AM Solar did my solar system, the controller was programmed to do a equalization. I ask why? Was told that the Lifeline batteries love this, and by the way, Lifeline is all the AM sold at that time. I don't know about now.
Call Lifeline and ask them, they have a ton of information that they will share for free. I did! 909-599-7816
And Lifeline calls it conditioning not equalization.
