What Fey Elektronik does

Fey Elektronik GmbH is a German specialty battery pack assembler and multi-brand battery distributor headquartered in Seevetal near Hamburg, founded in 1991 and operating as a wholly-owned subsidiary of the Swedish technology trading group Addtech AB. The company designs and manufactures both standard and customer-specific battery packs, with a core focus on lithium-ion pack configuration across 18650, 21700, 14500, and prismatic form factors at voltages from 3.6V to 36V, complemented by lithium primary packs, LiFePO4 packs, lead-acid batteries, NiCd/NiMH cells, button cells, alkaline-manganese batteries, and charging technology. Differentiated technical capabilities include an in-house UN 38.3 transport test laboratory that shortens lithium battery certification cycles, 100% outgoing inspection of all packs, use of brand-name cells (Panasonic, Saft, Tadiran, FDK) combined with proprietary pack design and safety circuitry, and a multi-standard certification footprint (ISO 9001, ISO 13485, ISO 14001, UL2054, UL62133-2, IEC62133-2). A producing subsidiary, Cellcon, shares the group's quality management system and handles production.

The company serves a primarily German industrial customer base, including industrial equipment manufacturers as the primary segment and medical technology OEMs as a secondary, regulated segment served under ISO 13485. Go-to-market combines an enterprise field sales motion, with three regional offices covering West (Willich), Central (Bad Oeynhausen), and South (Stuttgart) Germany, with a self-service e-commerce online shop (shop.feyelektronik.de) for standard products. Revenue is generated through one-time and recurring hardware sales of assembled packs and cells, plus professional services revenue from custom development and engineering collaboration. Distribution is anchored by a central warehouse in southern Hamburg stocking several thousand battery variants, enabling same-day delivery for numerous articles.
