Have a 3x longer lifetime compared to traditional lead-acid batteries. Performs incredibly well in extreme environments with a wide range of operating temperatures. Optima batteries are completely sealed, non-spillable and maintenance-free. Mounting options are endless for custom applications.

Test the Voltage First

1. 12.7 - 13.2 volts - NORMAL with 100% charge. Anything in this range means that you have normal charge and you're in the right range for an Optima.
2. 12.0-12.4 volts - LOW with 25-75% charge.
3. 0-11.9 volts - DISCHARGED.

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.

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.

AGM Optima batteries are known as compact batteries with a large capacity. This type of battery is equipped with the Spiralcell AGM technology (rolled lead), resulting in a considerably longer lifespan than conventional batteries.

AGM Optima® batteries are ultra high performance AGM products with advanced Spiralcell® Technology that can outperform all other lead-acid batteries.

about 12.6 to 12.8 volts For most car batteries in use today, typical battery voltage should be in the range of about 12.6 to 12.8 volts, including OPTIMA REDTOP batteries.

In fact, we indicate our REDTOP (and 34M BLUETOP) batteries are fully-charged at about 12.6-12.8 volts, while our YELLOWTOP and BLUETOP (except the 34M) batteries are fully-charged at about 13.0-13.2 volts.

And that that solution is made of a diluted form of sulfuric acid. The difference is irregular wet cell battery like you find in most vehicles.

about 13.0-13.2 volts OPTIMA obviously makes BLUETOP batteries as well and the normal voltage for those batteries is also about 13.0-13.2 volts, except for the 34M BLUETOP, which is the marine version of our Group 34 REDTOP starting battery.

And that that solution is made of a diluted form of sulfuric acid. The difference is irregular wet cell battery like you find in most vehicles.
