16 Which Optima Should I Use? There are three different Optima batteries on the market, RedTops, YellowTops, and BlueTops. The RedTop is best suited if your primary need is high power cranking and you are not running aftermarket in-car electronics. The YellowTop is best if you run key-off electronics or if you have a high-demand audio system or multiple electronics and you need the battery to recover from deep power drains. The BlueTop is the marine/RV line and is better suited for those applications.
