The difference is how the electrolyte is fixed and penetrated inside the battery. AGM is an ultra-fine glass fiber separator, which is used to absorb the electrolyte and provide oxygen composite channels. The gel-like sio2 is used to fix the electrolyte in the gel battery.

The AGM battery uses pure sulfuric acid aqueous solution as the electrolyte, and its density is 1.29-1.3lg/cm3. Most of it exists in the glass fiber membrane, while a part of the electrolyte is absorbed inside the plate. In order to provide a channel for the oxygen precipitated from the positive electrode to the negative electrode, it is necessary to keep 10% of the pores of the diaphragm not occupied by the electrolyte, that is, the lean liquid design. The pole group adopts a tight assembly method so that the plates can 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 thicker, and the positive grid alloy is Pb’-q2w-Srr--A1 quaternary alloy. The AGM type sealed lead-acid battery has less electrolyte, the thickness of the plate is thicker, and the utilization rate of 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 with today's gel-sealed batteries, the discharge capacity is smaller.

Compared with batteries of the same specification, the price is higher, but it has the following advantages:

The cycle charging capacity is 3 times higher than that of lead-calcium batteries, and it has a longer service life.

Higher capacitance stability over the entire service life.

Low temperature performance is more reliable.

Reduce the risk of accidents and reduce the risk of environmental pollution (because the acid is 100% sealed)

Maintenance is simple and reduces deep discharge.

Colloidal lead-acid battery adopts gel-like electrolyte, and there is no free liquid inside. Under the same volume, the electrolyte capacity is large, the heat capacity is large, and the heat dissipation ability is strong, which can avoid the thermal runaway phenomenon that is easy to occur in general batteries; the electrolyte concentration is low. The corrosion effect is weak; the concentration is uniform, and there is no electrolyte stratification.
