Optima Batteries are part of the Johnson Controls worldwide empire. JC is a major player in automotive electronics, interiors and seating, as well as prominent in industrial applications like HVAC, sustainability and security. Optima batteries have become the best solution for high-performance batteries for vehicles, whether needed to deliver the highest cranking amps, the most power, or the maximum number of deep-discharge cycles.
Conventional lead-acid flooded-cell batteries are a technology that’s more than a century old, and on a price-performance ration, they’re hard to beat. On the other hand, they have disadvantages: they need distilled water added regularly, they don’t tolerate being deep-discharged, and are liable to spill or leak acid in the case of a rollover or accident. Optima batteries use basically the same lead-acid chemistry, but are a major improvement over wet batteries.
There’s no liquid sulfuric acid electrolyte in an Optima Battery. Rather than leaving the lead plates in liquid that can splash and spill, the optima’s electrodes are separated by a fibrous mat, and the electrolyte is simply soaked into it. With no liquid aboard, the battery can’t ever leak or spill. The advantage of this AGM (Absorbed Glass Mat) style of construction is mechanical: the plates aren’t floating free, and are actually pressed against each other, locking them together. That means they can be made of purer (99.99%), softer lead that has less electrical resistance.
Because the electrolyte is trapped in the mat, hydrogen and oxygen generated by charging the battery are recombined into water, meaning an Optima battery doesn’t need water, ever. It’s sealed to keep those gases inside, preventing the escape of potentially explosive hydrogen. So you don’t need to worry about battery explosions like you should with a conventional battery.
Because the lead plates are so flexible and thin, Optima can use its exclusive Spiralcell technology. Instead of stacking plates up like a deck of cards, the two electrodes are wound up like a jelly roll, giving the Optima its unusual 6-pack appearance. Tight tolerances in winding the roll and manufacturing the case means the jelly roll can be a precise fit for the inside of the case, eliminating vibration or extra parts to prevent it. Optima batteries’ precision-molded cylindrical cases are made to such tight tolerances that only virgin polypropylene can be used.
The extremely pure lead used has two other advantages: the most obvious is a lower internal resistance because no alloying metals are needed for strength. This means a much lower internal resistance and a higher cranking capacity under high-load demands. Purer lead also means a very low self-discharge rate, meaning a battery that’s charged before its stores will keep its charge for many months, far longer than a conventional flooded-cell battery.

I have enjoyed using Optima batteries at word to power trolling motors. So, I purchased two Optima Yellow Tops, Group D34/78 for my ford f350 diesel. They performed beautifully over the past winter. They are easy to install, have great appearance and a good value. 5 stars all around.

I was looking for a different battery for my H3. I couldn't find a battery that would ship to an APO address. I was keeping doing research until I found your website. Next was ordering. Didn't have any problems, but it took more than a week. Thank you so much.

Awesome battery. The LS3 L92 with 11 to 1 compression. The battery has no problem with starts. Motor is brand-new and still a little tight. Still no problems.

I have this one powering my vehicle and one for my sound system. If I ever have to replace it, I will never buy any other type of battery.

This battery has definitely improved my car's performance. The lights never dim when turning on the car. Their crank is healthy and never lags when turning over in cold weather.

This battery did everything I wanted. It powered my HDTV during tailgating for four hours and started the truck with no problem. Just what I was looking for.

Best batteries by far! I use lots of accessories and with a high output ALT this battery does the job. Lots of reserve power for the Optima Yellow Category. I recommend it as your next Battery.
