From bumping stereo systems to hard-pulling winches, power-hungry accessories gobble up traditional car batteries faster than hot dogs at a competitive eating match. Keep your electronics fully fed with the OPTIMA Yellow Top Battery. This dual purpose deep cycle and starting battery cranks out enough juice to satisfy the most demanding gear.

The difference between the OPTIMA Yellow Top Battery and old-school car batteries comes down to the guts. 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.

High quality

Best battery I ever bought. Very reliable especially if you have a high powered sound system in your car. Will probably buy another one the next time I need one.

Disappointed

Great customer service from the guy I spoke to on the phone. The problem I have with the battery came with a cracked bottom piece on the plastic. Lucky it isn't into the battery. I didn't give it back because I need the battery for my car right now. So I had to makeshift fix it with duct tape. Not what I expected to get with a very expensive battery.

The Undisputed!

There is no question on which battery performs better. The only REAL question is red, yellow or blue.
