The Duracell Ultra Flooded is a 12V lead-acid car battery rated at 650 cold cranking amps in a BCI group size. It is a conventional flooded battery, not AGM, so it suits cars with standard charging systems and no start-stop demands. Duracell licenses its name to a major battery maker, and the Ultra line is sold as a step up from basic flooded batteries with more cranking power for V6 and small V8 engines. Reviewers treat it as a solid, no-frills replacement rather than a premium long-life pick.
