About Wyon

Our company

Wyon was founded in 1999 by Paul Wyser, his wife Marie-Theres, and their son, Philipp.

The custom-shaped battery manufacturer is based in the beautiful Appenzell region of Switzerland. The plastic technology that has established Wyon's reputation worldwide was first developed in the family's garage. Since 2005, the company has continued to grow and introduce other battery innovations. Today, its familiar company culture and commitment to customer benefits and developing high-quality technology are stronger than ever before.
