I just purchased 2 Optima Blue top batteries, one was not fully charged so I want to put it on the charger. I have no idea wheather it is a "Wet" battery or an "AGM" Absorbed Glass Mat battery. I went to the web site for Optima and no description was found. I have three options on the charger wet,gel,or agm. I don't want to mess up the new batteries on the wrong cycle. Does anyone know which kind of battery it is?
