What Renata Batteries does

Renata SA is a Swiss micro-battery manufacturer headquartered in Ittingen, Switzerland, and operating as a wholly-owned subsidiary of the Swatch Group since 1982. Founded in 1952 as a maker of mechanical clock components, the company has specialized in coin cell batteries for more than seven decades and now serves medical technology, industrial IoT, consumer electronics, hearing aid and wearable device markets globally. Its product portfolio spans silver oxide cells (including high-pulse variants for wireless medical applications), 3V lithium batteries, rechargeable lithium-polymer and lithium coin cells, thin-film batteries, zinc-air hearing aid batteries, tabbed coin cells and battery holders. The company also sells on-demand custom battery solutions, with more than 900 customer-specific designs developed to date, and offers multiple professional packaging formats including certified child-proof options.

The business operates a fully automated silver oxide production line and an in-house recycling facility with annual capacity of up to 250 million batteries, supporting its compliance posture under ISO 9001, ISO 14001, EN 862, US 16 CFR 1700.20, EU Battery Regulation, REACH and RoHS frameworks. Renata generates revenue primarily through B2B hardware sales: standard coin cells move through an authorized distributor network covering 70+ countries (including Future Electronics and Rutronik), while custom solutions are sold directly to enterprise customers in medical, industrial, informatics and logistics via a Key Account Management team headquartered in Switzerland with regional subsidiaries in Germany, Italy, France, Singapore, China and the USA. Logistics services out of the Miami office round out the offering.
