Just be sure not to overcharge them,,,as they don’t like much over 14v of pressure....I’ve got a yellow top in my Blazer that’s date coded 2007’ & still kicking strong....but over past 4-5’ish years-the red top has surpassed the yellow on cca’s.
One of my biggest reason for using them is “0” corrosion @ terminals...but the installer has to thoroughly clean everything up well first.
