Schauer Battery Chargers represents the combined strength of multiple trusted names in battery chargers, transformers, power supplies, and electronics. Based in Cincinnati, Ohio, our roots run deep—over 100 years of engineering excellence, with 2007 marking a full century of continuous innovation.

In the early 1930s, DC power supplies were built for independent telephone companies. As utilities evolved, so did we—powering everything from Western Union lines to ITT international communications, even the iconic tote board of the New York Stock Exchange.

Schauer has always led the charge. In 1947, we held the original patent for battery chargers using selenium rectifiers, leaving behind outdated tube technology. We pioneered the use of copper oxide, silicon, and germanium components—constantly evolving to meet modern needs.

Our innovation streak continues today. From automatic charging technology to high-frequency switching chargers for lead-acid batteries, Schauer has consistently introduced industry firsts in switching, metering, and rectification—many of which are now industry standards.

Every Schauer Battery Charger comes backed by our commitment to quality and a two-year limited warranty—because dependable power should be a guarantee, not a gamble.
