AGM Batteries

Metro AGM Automotive Batteries Explained

AGM L5 Batteries

AGM Batteries

  • AGM batteries have Improved active mass efficiency, through better absorption of the acid
  • Increased lifespan due to minimal active material shedding due to battery design
  • Higher cold start values
  • Totally Maintenance Free – zero water consumption
  • Spill proof/leak proof
  • Designed to meet the latest OEM vehicle demands
  • Compatible with sensitive electronic equipment
  • AGM technology is now factory fitted to numerous luxury cars and “Stop–Start” vehicles where increased AGM battery features are required

Metro’s world-leading industrial AGM (absorbent glass mat) technology comes to the automotive market. The Metro automotive AGM battery has been engineered to meet the growing extreme power demands of recently introduced vehicles now starting to enter the European aftermarket. Metro’s automotive AGM experience comes from vehicles such as; the first generation AGM on cars for the likes of the Mazda MX5 and the famous Toyota Prius and has now been launched for European vehicle battery designs in the likes of all leading car manufacturers i.e. Audi, BMW, Mercedes, Volkswagen, Lamborghini, Ferrari, Rolls-Royce, Bentleigh, Maserati, Ashton Martin, and some new generation STOP-START Japanese manufacturers etc.

The new Metro AGM European L-2, L-3, L-4, L-5 and L-6, sized batteries provide reliable starting whilst coping with the extreme power needs of the modern vehicle. Laboratory evaluation is boasting 4-5 times the cyclic durability of standard conventional flooded product and typically 16-20 % higher starting power, even at lower temperatures. Increased reaction surface area ensures increased energy densities for faster engine rotation during starting and therefore maximising fuel efficiency.

The AGM batteries utilises the same absorbent glass mat technology as used in Metro Industrial batteries which have been on the market for over 40 years from some renowned car battery manufacturers from all around the world. This absorbent glass mat absorbs the battery’s acid, enabling a more efficient use of the cell’s volume without the need for electrolyte reservoirs, as needed with conventional flooded batteries. The absorbent glass mat gives a number of key benefits to the design of the lead acid battery:

· Within normal operating conditions, the use of the individual cell valve design and glass mat plate separation ensures gas recombination occurs and ensures that no water is lost therefore negating the need for electrolyte reservoirs and freeing the user from maintenance.

· One way venting system providing partial pressure in each cell ensuring 100% leak proof and safe handling.

· The acid absorption of the glass mat means that the battery packs can be operated under higher pressures than conventional flooded batteries this has benefits including significantly prolonging battery cycle durability by minimising paste shedding.

· The increased pack pressures of the AGM battery increase the batteries resistance to vibration.

· More reaction surface area ensuring higher starting capacity within the same footprint as conventional flooded batteries.
