Dryfit technology was developed by Sonnenschein and to this day, no other comparable product on the world market has been able to match the performance of original dryfit batteries.

As a brand of the EXIDE Group of Companies, the worldwide number one in the market for lead batteries, Sonnenschein makes a decisive contribution to the dynamic growth of this group of companies. The leading edge technology and experience of one of Germany's most long-standing companies complement in an almost perfect manner the product strategy of the EXIDE Group, which was founded almost 100 years ago by the ingenious inventor Thomas Alva Edison.
