The AGM battery is an early inventive, and a wider storage battery is used. It is a valve-controlled sealed lead storage battery (also known as VRLA storage) with a glass precision sealing plate (AGM). Sulfuric acid is absorbed by very fine glass fiber mat to prevent the battery. This can be limited without a hazardous material, which can be flat, similar to the standard submerged lead-acid bag in the rectangular box, and they can also be wound into a cylindrical battery.
The AGM storage battery has a very low internal resistance that provides high currents on demand and provides relatively long service life even in the depth cycle. AGM storage battery is maintained, providing good electrical reliability and is lighter than lead-acid battery. Although conventional lead-acid batteries need to be poured every six months to prevent the accumulation of sulfurization, the AGM battery is not easily sulfurized, and longer time can be stored before it is necessary to charge. The battery is good at low temperatures and low discharge rate.
The advantage of the AGM battery is that the charging speed is 5 times faster than the lead-acid battery, and has a deep cycle. The AGM battery supplies 80% discharge depth, on the other hand, the lead-acid battery is designated to achieve the same cycle life, the negative surface is slightly low, the manufacturing cost is higher than the lead-acid battery, but is cheap than the gel battery . Most batteries are medium-sized batteries, and the battery voltage ranges from 30 to 100 AH. They can also be found in UPS, regardless of size, for fixing and deep cycle. AGM batteries are typically fabricated in size and can be used in high-end vehicles, such as heating seats, steering wheels, rear view mirrors, and windshields.
At the same time, the AGM storage battery is the preferred battery of a high-end motorcycle. The AGM storage battery seal can reduce the acid overflow in the accident to reduce weight to obtain the same properties, and allow mounting in an odd angle. AGM batteries can also be used in ships, automotive and robot applications due to low temperatures. The AGM battery is entering the car’s start stop. The classic lead-acid battery is not strong enough, and the recycle will have a significant capacity attenuation after two years.
As with all gels and sealing devices, the AGM battery is very sensitive to overcharge. Charging to 2.40V / battery (and higher) is good. However, the floating charge should be reduced between 2.25 and 2.30V / batteries (lower temperature in summer). The automotive charging system for lead-acid batteries typically has a fixed floating voltage setting of 14.40V (2.40V / battery), and the use of a sealing device can be directly replaced to overcharge the battery on the long drive. The AGM batteries and other sealing batteries are not suitable for heating, and should be installed away from the engine compartment. If the battery core reaches 49 ¡ã C (120 ¡ã F), the charging is stopped. The following table lists the advantages and limitations of the AGM batter
