How much do you know about AGM batteries?

GM battery, is the earlier invention, the broader the battery. It is a valve-regulated sealed lead storage battery (also known as VRLA battery) using glass fiber separator (AGM), represented by some Japanese battery companies. This type of battery is a type of VRLA battery. The AGM type battery uses a pure aqueous solution of sulfuric acid as an electrolyte having a density of 1.29 - 1.3 lg / cm 3 . Most of them are present in the glass fiber membrane, and a part of the electrolyte is absorbed inside the electrode plate. The AGM type sealed lead storage battery has a small amount of electrolyte, the thickness of the electrode plate is thick, and the utilization rate of the active material is lower than that of the open type battery, so the discharge capacity of the battery is about 10% lower than that of the open type battery. Compared to today's colloidal sealed batteries, the discharge capacity is smaller. The price is higher than that of the same specification battery. AGM batteries have a wide range of applications in energy-efficient vehicles, and international large-scale vehicle companies have energy-saving automotive products that support AGM batteries.
