Shenzhen Maintenance-Free Lead-Acid Battery Wholesale, Shenzhen Maintenance-Free Lead-Acid Battery Price, Shenzhen Maintenance-Free Lead-Acid Battery Supplier [Shenzhen Nuoner Power] Lead-acid battery (VRLA) is a battery with electrodes mainly made of lead and its oxides, and an electrolyte solution. In the discharge state, the positive electrode is mainly composed of lead, and the negative electrode is mainly composed of lead; in the charging state, the main components of both electrodes are 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 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, and so on. Key Features Lead-acid battery In normal operation, the electrolyte will not leak from the battery terminals or housing. No free acid Special absorbent separators keep the acid contained, with 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 the normal level, the VRLA battery releases excess gas and automatically reseals, ensuring no excess gas inside. Easy Maintenance Due to the gas recombinant 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 structured lead plates can be used in float charging for 10-15 years. Quality Stable and Reliable The production process and strict quality control system ensure the stable quality and reliable performance of VRLA batteries. Voltage, capacity, and sealing are inspected online.
