The next generation flooded cell battery.

PFX Technology delivers maximum performance in multiple applications, improving energy conductance, heat resistance, cyclability and increasing the overall life of the battery.






Quality made in the USA.

Superior and Superlex batteries are completely designed and manufactured in the United States, with 95% of raw materials in every battery generated domestically and 60-80% of lead and plastic recycled from spent batteries. Superior utilizes closed-loop manufacturing processes, ensuring materials are cleaned and reclaimed in every situation possible.










The science of highly
refined lead.

Superior's lead is cleaned of unstable contaminants before it reaches our facility, leaving only the chemical elements that guarantee excellent battery performance. Through an in-house, quality-controlled process, we manufacture the lead alloy used in our batteries, establishing the right chemical composition to decrease corrosion, reduce grid growth and increase battery life. Each roll of cast lead strip is inspected to ensure it meets Superior's proprietary metallurgical and electrochemical performance standards.





Better mix = better performance.

CPM or Continuous Paste Mixing is a precision-metered mix that controls the ingredients in bonding paste. This process offers better performance than a standard batch mixer. A better mix = better battery performance.  





We've got the cure.

Superior's plates are cured in micro-process controlled, state-of-the-art hydroset curing chambers. These chambers precisely control all humidity, heat and drying during different stages to have an exacting cure of the plates.

What separates us from the rest?

Superior and Superlex® batteries feature the Daramic® Duralife high-performance polyethylene battery separator (above). This separator extends battery life, enhances cyclability and improves paste-to-lead bonding performance. In our deep cycle applications, a glass mat (microscopic view below) is fused with the positive plate to improve battery life and prevent mass shedding. Glass mats also offer excellent chemical and oxidation resistance.

Formed just in time.

Though components are manufactured daily, the vast majority of our batteries are not formed — or filled with electrolyte solution — until an order is placed. Validated by date stamp, this unique feature of Superior batteries means our distributors are getting batteries in the earliest stage of life, and consumers are experiencing fresher and longer battery performance.
