General Purpose VRLA AGM Battery

The now-widely used valve-controlled lead-acid battery (VRLA) uses AGM (absorptive glass mate) as its partition (hereafter called Agm Battery). The sulfuric acid electrolyte of the battery is absorbed in the AGM separator and positive and negative plates, and the sulfuric acid electrolyte of the colloidal VRLA Battery is fixed in the GEL of silica (hereinafter referred to as gel cell).

The electrolyte of AGM Battery is fixed in the micropores of fine glass fiber felt, and there is no free flowing electrolyte in the battery. During overcharging, the oxygen generated by the positive electrode reaches the negative electrode through the pore channel in the AGM, and oxygen recombination reaction occurs to complete the closed oxygen cycle (the silica GEL of GEL battery will form fine cracks in the use of the battery, and become the pore channel for oxygen to reach the negative electrode ).

AGM batteries are suitable for floating charging and are often used in UPS that require high power output. This type of battery has a service life of about 5-10 years and a cycle life of about 200-500 times (80%D0D). The end of battery life often shows the increase of internal resistance, and the negative sulfation is an important cause of battery failure. At present, the vast majority of electric bicycles in China use AGM batteries as power, with a lifespan of about 1-2 years.
