Supplier Snapshot: Sonnenschein

In 1910 Dr. Theodor Sonnenschein founded the Accumulatorenfabrik (literally: battery factory) Sonnenschein in Germany. A student of Max Planck, Theodor already began to develop and manufacture batteries and energy storage cells during his studies.

Sonnenschein stayed a family-owned business for many years to come, renowned for its innovative and high-quality products.

In 1992 the German company was taken over by the Italian battery manufacturer CEAC before becoming part of the US-American battery manufacturer Exide Technologies in 1996.

For the last 20 years, Sonnenschein has maintained its excellent reputation for quality technology, widening its product offering and manufacturing its outstanding Sonnenschein batteries under the German arm of Exide Technologies.
