  • Having accumulated a wealth of experience and expertise in the design and production of battery ancillaries, ABERTAX has positioned itself as a leading developer and manufacturer of advanced battery accessories and components for energy storage systems and is the preferred supplier of many international battery, industrial vehicle, and machinery manufacturers.

    The integrity of our products and how we design and manufacture them is fundamental. When Abertax was founded in 1999 we pledged to only offer products which were innovative, responded intelligently to the demands of modern industry, and yet complemented and supported the environment. It’s a matter of immense pride to the Abertax team that we have held fast to these values for over a decade.

      • The Battery Monitoring System (BMS)
      • The Capacitive Level Sensors (CLS)
      • Gas Release Valves (GRS)
      • Intelligent Battery (IB)


    All products primarily aimed at use in the battery environment. Further in our range we offer Magnetic Valves (MV) for industrial cleaning machines and for Roof Tanks / Water Storage Tanks.

    Research and Development is an ongoing process with a team of electrical, electronic and chemical engineers with more than 25 years of experience in battery technology.
