Lead acid battery (VRLA) is a type of battery with electrodes mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of lead-acid batteries, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; In the charging state, the main component of the positive and negative electrodes is lead sulfate. The nominal voltage of a single cell lead-acid battery is 2.0V, which can discharge to 1.5V and charge to 2.4V; In applications, six single cell lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery, as well as 24V, 36V, 48V, etc Main features Safety sealing During normal operation, the electrolyte will not leak from the battery terminals or casing. . There is no free acidSpecial suction separator to keep the acid inside, and there is no free acid inside the battery, so the battery can be placed in any position After the internal pressure of the battery exceeds the normal level, the VRLA battery will release excess gas and automatically reseal, ensuring that there is no excess gas inside the battery Easy maintenance Due to the gas recombination system converting the generated gas into water, there is no need to add water during the use of VRLA batteries. Long service life VRLA batteries with corrosion-resistant lead calcium alloy fence plates can be used for floating charging for 10-15 years. Stable quality and high reliability Adopting advanced production processes and strict quality control systems, VRLA batteries have stable quality and reliable performance. . 100% inspection of voltage, capacity, and sealing on lineSecurity Certification Function of testing report:1.
