My car is a 2005 Buick Century Custom. The stock batteries has the terminals of the side, not on top. Since Kinetik does not make a battery with side terminals, I was thinking about using a Optima YellowTop battery under the hood, and then wire it in parallel to a Kinetik battery in the trunk for amplifiers. I know Optima and Kinetik batteries each use different materials in their batteries, and on paper, Kinetik is much better. Is it a bad idea to use this combo, assuming they are both manufactured and purchased within a week of each other? Or do I have to pick one brand and use it entirely for batteries?
