Our thick-framed cast grids increase cycle life in our Par One Series battery.

Our deep cycle separators in the Par One Series eliminate shorts between positive and negative plates, reduce water loss and prevent shedding of active material. Glass fibers add plate strength and endurance and provide more robust power for the battery.

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.

This additive allows for better utilization of the battery's components, increased surface area and better performance in hot climates.
