Optima YellowTop Deep-Cycle 12-volt batteries are high-performance, dual-purpose power sources. They're great for applications requiring repetitive amperage drain and quick recharging—like trucks with winches, commercial or public safety fleets, and vehicles loaded with electronics and accessories. YellowTops also power forklifts, tractors, and other heavy equipment. The maintenance-free AGM batteries deliver premium ignition starts, while sustaining high power levels even when system loads exceed the alternator output. Optima deep-cycle models are sealed, spill-proof, and can be mounted in most any position. They are far more resistant to vibrations than standard batteries, and will perform up to three times longer. For consistent power and faster recharges, order the YellowTop designed for your needs.

Optima Yellow Top battery

Summit RacingSummit Racing Verified Purchase

ULT-9012-021
Had a Optima Red Top for eight years and it never failed but it seemed to be minimum for battery performance. The Yellow Top has the extra capacity that I wanted with instant power. Glad I spent the extra money. Battery fit my car perfectly by using the included spacers.

Summit RacingSummit Racing Verified Purchase

ULT-9012-021
My originally purchased battery lasted exactly 1 year before it completely failed. Usually I give a product the benefit of doubt and just return it under the conditions of the warranty. Sometimes things go bad and it doesn’t mean the entire line of products is bad. Unfortunately that is not the case with optima batteries. While returning my battery to summit the person behind the counter told me they are getting optima batteries returned daily. The problem is obviously greater than just a bad batch. Next the counter person informed me that optima changed their warranty terms. My replacement battery warranty does not start on the day of replacement. It begins on the date of original purchase! So now my battery with known problems only has a 2 year warranty. Conceivably my next replacement battery will only have a 1 year or less warranty. Shame on you optima! You are riding your history and avoiding treating your customers with the respect deserved. My next purchased battery will not be an optima and I will ensure that all of my friends and family are aware of optima’s committment to poor customer service. There are many other batteries that are just as good from manufactures that will stand by their product. ...read more

I spent the extra $$ because I wanted a battery that would last and be a solid performer on my classic car. 2 years in and one or two cells are dead. When garaged 98% of the time it was on a battery tender. Very disappointed.

Best Battery Ever

ULT-9012-021
I have been using car batteries since 1974, this is the most awesome battery I have ever used. I use one of these in my race car & has outlasted any other brand I've tried. I even had an XS Power 16V Battery & in 1 month it was dead. Even the Optima Red tops are bad, never had one make it a full year. The yellow top I have now is over 5 years old, has been frozen twice & still holds a charge. ...read more
