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, and is a key component of our revolutionary PFX Technology®. A better mix = better battery performance.

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.

The lawn and garden series features a computer-aided design flush cover to help with easy installation.

Superior's expanded positive grid construction provides increased cycle life to our lawn and garden battery line.

Superior and Superlex® batteries feature the Daramic® Duralife high-performance polyethylene battery separator. This separator extends battery life, enhances cyclability and improves paste-to-lead bonding performance.

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 and Superlex® batteries means our distributors are getting batteries in the earliest stage of life, and consumers are experiencing fresher and longer battery performance.
