Tovarna Akumulatorskih Baterij (TAB)

What Tovarna Akumulatorskih Baterij (TAB) does

Tovarna Akumulatorskih Baterij (TAB) is a privately held Slovenian battery manufacturer founded in 1965, headquartered in Mežica, operating four advanced production facilities across Slovenia and North Macedonia. The company produces both lead-acid batteries (starter, traction, stationary, and monoblock formats under brands TAB, TOPLA, VESNA, VOLTHOR, and MOTION) and lithium-iron-phosphate (LFP) batteries for traction (e.motive line), energy storage (e.storage / containerized ESS), and leisure applications (e.leisure line). Combined annual capacity exceeds 6 million battery units, including a dedicated 1 GWh Li-ion line in Prevalje. TAB is vertically integrated through wholly-owned MPI-Reciklaža d.o.o., which processes approximately 55,000 tonnes of scrap per year into 30,000 tonnes of soft lead and alloys, providing an internal recycled-lead feedstock.

The business model is B2B hardware sales via a network of eight subsidiaries (Italy, Spain, Poland, Croatia, Serbia, Macedonia, Baykal, and as of March 2025 the UK via a 51% stake in Battery Service Hub), regional agents, and direct OEM contracts. Named OEM relationships include Volkswagen Group (since 2018), Stellantis/PSA (Peugeot, Citroën, Opel), Audi, Airbus, Fiat (since 1972), and Renault. The company prices through quotation-based multi-year contracts, holds ISO 9001, ISO 14001, IATF 16949, ATEX, and IECEx certifications, and operates in 12+ countries across Europe, Asia, and the Americas.

Revenue is not publicly disclosed. The customer base spans four primary verticals: automotive OEMs and aftermarket, industrial material handling (forklifts, logistics), stationary/backup power and grid-scale energy storage (including commissioned BESS projects for Neoenergija and HSE), and leisure/mobility (marine, RV, solar). TAB is pivoting from a lead-acid-dominant heritage player into LFP-based Li-ion traction and turnkey BESS deployment, supported by roughly €4.43 million in EU/NextGenerationEU grants for Li-ion production, VRLA R&D with carbon nanotube additives, and IoT/blockchain-based digitalization.
