Product details
The EB20-12EB Series is a 12V valve-regulated lead-acid battery produced by B.B. Battery. It adopts absorbent glass fiber separator technology, enabling efficient gas recombination, thereby ensuring the battery is completely maintenance-free throughout its entire service life without the need to add any water. The battery is designed with safety and durability in mind. Its shell is made of sturdy impact-resistant ABS plastic. The battery cover is tightly connected to the shell, and the terminal area is specially sealed to effectively prevent electrolyte leakage, complying with the design standards of free acid-free and leak-proof.The six liquid filling holes on the top of the battery are used for filling electrolyte during production, followed by installing a pressure relief valve made of non-combustible materials. This design significantly enhances the battery's fire and explosion safety level.
In terms of technical parameters, EB20-12 has a nominal voltage of 12V, a nominal capacity of 20Ah at the 20-hour rate, and a capacity of 15Ah at the 2-hour rate. The total weight of the battery is approximately 6.45 kilograms (14.22 pounds). It has a compact size: length 181 mm (7.13 inches), width 76 mm (2.99 inches), and height 166 mm (6.54 inches). The terminal configuration is flexible. The standard type is B1, located at position 7; users can also choose to equip type I1 terminals, which are located at position 6.This structural design endows the battery with extremely high installation flexibility, allowing installation in horizontal and vertical directions (excluding inversion), adapting to various complex equipment layout requirements.
The core advantage of EB20-12 lies in its high power output and excellent cycle performance. Both positive and negative plates are coated with specially formulated paste-like active materials. Combined with an optimized internal design, the battery can provide stable high-power discharge and has a cycle life of up to 1300 cycles. Under general standards, the expected service life can reach 5 to 7 years. The capacity ranges from 12 to 150 ampere-hours, with specific values depending on different discharge rates (such as C2, C5, C10, C20, etc.).These characteristics make it an ideal choice for application scenarios with extremely high power supply reliability requirements.
In practical applications, the EB20-12 series batteries, with their high reliability, maintenance-free, and easy installation features, are widely used in uninterruptible power supply (UPS) systems, telecom base stations, various medical electronic devices, electric wheelchairs, electric bicycles and scooters, lawn mowers, and golf carts, among other equipment. Whether providing backup power for critical infrastructure or long-lasting power for personal mobility tools, it ensures efficient and safe energy supply, meeting the stringent requirements of high power and high cycle usage.
