# Advanced Battery Concepts

> Advanced Battery Concepts is a Clare, Michigan battery maker that did something contrarian: instead of chasing lithium, it went back to lead-acid and reinvented it. Its patented GreenSeal bipolar architecture cuts lead content while boosting cycle life, and the company has licensed the design to global battery giants like Clarios, EnerSys, Exide, Crown and Trojan. With its EverGreenSeal line and BatteryBarn utility systems, ABC builds non-flammable, fully recyclable, domestically manufactured energy storage for critical infrastructure and the grid.
