Anyone else have problems with agm battries?? Got a fix for ya
Well i have been doing some research the past few days and found that a battery shutoff switch and a regular charger wont cut it anymore. Have you heard of sulfination?? Sounds like a line of crap right. When most rods go into hybernation for the winter we disconnect the battery or should. Well the past three springs i have had what i thought was more than one bad optima battery in customers cars plus my own. I was not happy about the latest one because it was my deep cycle. Well after talking to my optima rep with the intention of never using him again he talked me off the ledge. He said that agm battries will sulfinate when they drop below 12.4 volts and require a charger that desulfinates to bring them back. Low and behold he was right. I have three battries that were replaced sitting on the shelf and i bought a new desulfination charger and guess what They went from not holding a charge for more than 3 hours to being like new again. Google it its real and just justifies a battery maintainer for cars that sit for months at a time. Or justifies moving to a warm climate where you can drive your rod year round….
