The benefits of AGM over GEL are that with the use of absorbed glass mat, the battery pack can be operated under a greater operating pressure so improving cyclic durability. The major difference is that in the AGM, the electrolyte is fully soaked into a special absorbed glass mat separator which immobilises the acid, whereas in the GEL batteries the acid is mixed with Silica to form a GEL also immobilising the acid. under normal operating conditions they recombine the gases given off during charging to form water) and both are classified as sealed valve regulated. What are the differences between GEL and AGM (starved) batteries?Ī. The automotive application battery designs are balanced with greater high rate starting performance and cycle life for the increased service/technological requirements of modern vehicle designs. This experience has been gained by Yuasa from over 44 years experience in the field using this technology. The quality of the glass mat is a critical item in ensuring the optimum life of the battery versus its application. The design benefits of the glass mat over conventional flooded batteries enable the battery pack to operate under higher pressure without the fear of insufficient electrolyte between the plates, leading to the step change in durability offered by AGM batteries over flooded. See above, AGM batteries are built using a glass mat separator which enable all the electrolyte required by the battery to be stored within the glass mat, also allowing any gasses given off during charging to be recombined into water meaning that the batteries are totally maintenance free. What are the differences between flooded and AGM Lead Acid batteries?Ī. More reaction surface area ensuring higher starting capacity within the same footprint as conventional ?flooded batteries.The increased pack pressures of the AGM battery increase the batteries resistance to vibration.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.One way venting system providing partial pressure in each cell ensuring 100% leak proof and safe handling.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.The absorbent glass mat gives a number of key benefits to the design of the lead acid battery: 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 AGM batteries utilises the same absorbent glass mat technology as used in Yuasa Motorcycle and Industrial batteries which have been on the market for over 44 years (1965). Increased reaction surface area ensures increased energy densities for faster engine rotation during starting and therefore maximising fuel efficiency. Laboratory evaluation is boasting 4-5 times the cyclic durability of standard conventional flooded product and typically 16% higher starting power, even at lower temperatures. The new Yuasa AGM European 096 and 019 sized batteries provide reliable starting whilst coping with the extreme power needs of the modern vehicle. Yuasa’s automotive AGM experience comes from vehicles such as the Mazda MX5 and the famous Toyota Prius and has now been launched for European vehicle battery designs. The Yuasa automotive AGM battery has been engineered to meet the growing extreme power demands of recently introduced vehicles now starting to enter the European aftermarket. Yuasa’s world leading motorcycle and industrial AGM (absorbent glass mat) technology comes to the automotive market.
