Hey, they are fresh batteries and dated to 2020, and this is not CBS 2020 either. Have good voltage when checked w/ a VOM meter thing. I don't know about the innards of these things, and I am not going to open one up cause I would not know what I was looking at, nor would I even care... lol REVIEW: All 4 gate openers work,.all 5 of my computers have new batteries for the cmos momory, and a couple of my IR radio controllers now function better, so all is OK here. If not there, that is easily remedied by purchasing some of these batteries...
