AGM type battery is an earlier, a wide range of batteries. It is a valve-controlled sealed lead battery (also known as VRLA battery) with a glass fiber separator (AGM) to represent some of Japanese battery companies. This battery belongs to a VRLA battery.
There is also a type of battery that is also a VRLA battery is a GEL type battery. In the 1990s, the development of communication and electricity has made the AGM battery development rapidly, high market share, and the GEL batteries are relatively low. AGM battery uses pure sulfuric acid aqueous solution of hydrolyzed liquid, its density is 1.
29-1.3Lg / cm3. Most of the glass fiber membranes are present, and the inner part of the plate is sucks part of the electrolyte.
In order to provide the positive absorbed oxygen to the channel to the negative electrode, the diaphragm must maintain 10% of the pores that are not occupied by the electrolytic solution, that is, a poor liquid design. The polar group uses a suitable method in order to make the plates fully contact the electrolyte. At the same time, in order to ensure that the battery has sufficient life, the plate should be designed to be thick, the positive plate alloy uses PB'-Q2W-SRR - A1 four yuan alloy.
The amount of electrolytic solution of the AGM sealing lead battery is small, the thickness of the polar plate is thick, and the active material utilization is lower than the opening battery, so that the discharge capacity of the battery is about 10% lower than the opening battery. Compared with today's colloidal sealing battery, its discharge capacity is small. Compared with the same specifications, the price is high, but it has the following advantages: 1.
Cyclic charging capacity is 3 times higher than the lead calcium battery, with longer service life. 2. Have higher capacitance stability throughout the service life cycle.
3. Low temperature is more reliable. 4.
Reduce the risk of accidents, reduce environmental pollution risk (due to 100% sealed pack) 5. Maintenance is simple, reduce depth discharge. At present, there are representative brands in the market: Jiangson, USA, China Sailing, Shanghai Extra, Camel Shares, etc.
