Optima has been manufacturing some of the most well-known, most reliable and most technically advanced Absorbed Glass Mat (AGM) batteries on the market for over 40 years. Optima was the first to market to introduce maintenance-free lead-acid batteries for the US Military.

But what about the OPTIMA batteries factory? Contrary to Internet speculation, it's not in China, but it is in Monterrey, Mexico and they make the best batteries in the world there.

Resistant to All Damaging Factors: They are corrosion resistant and ideal for all types of weather and temperatures. Over 15X More Vibration Resistance: Damage from vibration can cause battery failure, but Optima cells are tightly compressed to withstand even the most severe vibration conditions.

REDTOP® BATTERIES The REDTOP high-performance AGM battery is the ultimate starting battery and is designed to deliver a strong burst of ignition power for a reliable start-up every time. It has high-power delivery and extreme resistance to the most common causes of battery failure.

Deep Cycle Ability. For users with a high demand for power when continuous charging capability (like a trickle charger or alternator) isn't practical, the Yellowtop Optima is the better choice over the Redtop.

In an application like that, they could expect to see an OPTIMA battery last four to six years. However, in a more moderate climate, like San Diego, if someone might see four years out of a flooded battery, they could see double or triple that out of an OPTIMA.

While OPTIMA's Monterrey production facility is currently the only place where OPTIMA batteries are produced, OPTIMA's world headquarters and corporate offices remain in Glendale, Wisconsin, as part of Clarios. Take a virtual tour of the OPTIMA Batteries factory here.

We indicate our batteries can last up to three times as long as conventional flooded batteries, although actual lifespan can vary, based on a variety of factors, including the specific application, operating temperatures and maintenance habits.

AGM batteries All OPTIMA batteries are AGM batteries, but no OPTIMA batteries are gel batteries. The "g" in "gel" often gets confused with the "G" in AGM.

OPTIMA YELLOWTOP® batteries are protected from freezing down to -30°F when fully-charged to about 13.0-13.2 volts and our REDTOP® batteries are protected from freezing down to -50°F when fully-charged to about 12.6-12.8 volts.
