Battery lead acid LogicPower AK-LP4163 12V20Ah (20 А*h)

External universal battery manufactured using AGM technology is a completely sealed external power source that does not require maintenance during storage and operation. The manufacturing technology of AGM (absorbent glass mat) universal external batteries assumes the presence of an absorbent fiberglass pad inside the battery. Batteries of this type do an excellent job with increased loads. Advantages of AGM battery: The resource of charge/discharge cycles in an AGM battery is 400* (only 5 years, depending on the operating conditions). The battery can be installed in residential areas. The absence of free liquid electrolyte between the plates and the complete tightness of the housing eliminate the leakage of acid and guarantee the absence of harmful fumes. These batteries in practical use show stable results when operating at low (-20°C) and high (+50°C) ambient temperatures. In operation, the AGM lead acid battery is capable of withstanding long discharge, cyclic discharge, deep discharge and high current discharge. Batteries of this type have low self-discharge rates during long-term storage and reliable self-protection against overdischarge and overcharge of the battery. Features of the production of AGM batteries Inside the battery, made using AGM technology, cellular insulating gaskets of thin fiberglass are placed. Separators and electrode plates are tightly pressed against each other. Thus, free liquid electrolyte remains between the battery plates, since it is contained in the separator and in the active part of the electrodes. The amount of liquid electrolyte is dosed in such a way that small pores are filled with acid, and large pores ensure the circulation of gases. The design of the battery has an improved gas recombination system - oxygen and hydrogen, formed as a result of chemical processes, do not have time to evaporate outside the sealed case until condensation occurs. Applications: Why do I need an AGM lead-acid battery? Universal external battery charger use: In telecommunications and other communication systems, including as an external battery for charging mobile phones, walkie-talkies, etc. For equipment of video surveillance, security, security, fire and other alarm systems. In uninterruptible power supply systems of server stations. As a power source for medical, laboratory, trade and specialized equipment. In systems of accumulation of energy from other sources (batteries for solar batteries). As a battery for an emergency or LED lamp. As a battery for uninterruptible power supplies and UPS.
