Why the deep cycle AGM battery performance is good but the development is slow
2023-10-26
You may be unfamiliar with the name deep cycle AGM battery, but it is not a new product in the past two years. It has been widely used in many high-tech fields such as the power industry, and many small cars with start-stop functions are also equipped with batteries.

What are the advantages of deep-cycle AGM batteries?
Deep cycle AGM batteries are a new technology for lead-acid batteries, and AGM refers to the material of the separator. Common battery separators include rubber separators, PP separators, PE separators, PVC separators, and AGM separators. The deep cycle AGM battery uses pure sulfuric acid aqueous solution as the electrolyte, most of the electrolyte is absorbed in the glass wool separator (AGM), and the ordinary deep cycle AGM battery is the separator soaked in the electrolyte. The discharge performance of the deep cycle AGM battery is quite excellent. Take the most common lead-acid battery for comparison. The common battery can only discharge about 25% of the total power at most, while the deep cycle AGM battery can continue to discharge 50%, which is doubled, and the effect is naturally outstanding. And even if it is the same 220 Ah battery, the discharge capacity of the deep cycle AGM battery will be twice more than that of a normal deep cycle AGM battery. If it is changed to 330 ampere-hours, the discharge capacity is 165-ampere hours. The ordinary 220Ah discharges 25%, and the discharge capacity is only 45Ah. More power means that the deep cycle AGM battery life of the parking air conditioner can be greatly improved, and there is no need to worry about the phenomenon that the air conditioner will shut down after a while. In terms of deep discharge, the general battery does not support deep discharge, because frequent deep discharge will accelerate the aging of the battery and shorten the lifespan. Deep cycle AGM battery does not have to worry about this problem at all, it can carry out deep cycle discharge and stop discharge many times. In terms of service life, deep cycle AGM batteries are 4-5 times longer than ordinary batteries.

What are the reasons that hinder the development of deep-cycle AGM batteries?
Although the deep cycle AGM battery has excellent performance and is more durable, the price is also a lot more expensive. The price of a single 330 Ah deep cycle AGM battery is about 2500 yuan. You must know that an ordinary 180 Ah battery is only 1000 yuan. Although the price is more expensive, the advantages of the deep cycle AGM battery are the greater discharge capacity and the long life. At the same time, the original car chooses the deep cycle AGM battery, which can also save the later process of installing a separate generator, which not only reduces the cost but also reduces the weight of the vehicle. Of course, our company is also conducting intensive testing. In the future, we will also update to see deep-cycle AGM batteries in many industries.
