Instead of using flat sheets of impure lead, OPTIMA batteries are loaded with tightly coiled columns of 99.999% pure lead. This Spiralcell Technology ensures maximum vibration resistance, unbeatable output, ultra low ohms and nearly twice the lifespan of traditional batteries.

Forget about carrying around a bottle of distilled water in your trunk—your OPTIMA Yellow Top Battery is completely sealed and 100% maintenance free. You can even rotate your OPTIMA battery a full 180° without it dripping a drop. Plus, OPTIMA backs your Yellow Top Battery with a 36-month warranty.

OPTIMA Yellow Top Battery

Quick and easy install, and my vehicle did not require the provided spacers. I went with the Yellow Top so I can run my accessories longer with the engine off. Very pleased and looking forward to years of trouble free use.
