Maintenance-Free Lead-Acid Batteries, Manufacturer of Maintenance-Free Lead-Acid Batteries, Price of Maintenance-Free Lead-Acid Batteries, Supplier of Maintenance-Free Lead-Acid Batteries [Shenzhen Nuonai Power] Lead-acid batteries (VRLA) are batteries with electrodes mainly made of lead and its oxides, and the electrolyte is a solution. In the discharge state, the positive electrode is mainly lead; in the charging state, the main component of both positive and negative electrodes is lead. The nominal voltage of a single cell lead-acid battery is 2.0V, capable of discharging to 1.5V and charging to 2.4V; in application, six single cells are often connected in series to form a lead-acid battery with a nominal voltage of 12V, as well as 24V, 36V, 48V, and so on. Key Features: Lead-acid batteries, during normal operation, the electrolyte will not leak from the battery terminals or housing. There is no free acid. Special absorbent separators keep the acid inside, ensuring there is no free acid liquid inside the battery, allowing it to be placed in any position. Venting System: When the internal pressure of the battery exceeds normal levels, the VRLA battery will release excess gas and automatically reseal, ensuring no excess gas inside the battery. Easy Maintenance: Due to the gas recombiner system, the generated gas is converted into water, so no water needs to be added during the use of VRLA batteries. Long Service Life: Lead-acid batteries with anti-corrosion lead plates can be float-charged for 10-15 years. Quality Stable, High Reliability: The manufacturing process and strict quality control system ensure the stable quality and reliable performance of VRLA batteries. Voltage, capacity, and sealing are inspected online.
