Welcome to Battery University!

Battery University™ is a free educational website offering hands-on battery information to engineers, educators, media, students and battery users alike. The tutorials evaluate the advantages and limitations of battery chemistries, advise on best battery choice and suggest ways to extend battery life.

The information is compiled from specifications and independent test laboratories as well as crowdsourcing. Average readings are used when practical rather than citing research papers, as lab results are often not repeatable in real life. This differs from scientific papers published by academia and research laboratories for scientists.

Battery University™ is sponsored by Cadex Electronics Inc., a technology provider specializing in the design and manufacture of advanced battery packs, BMS, chargers and diagnostic devices.
