Product details

The EB20-12 model is a representative product in the EB series of B.B. Battery VRLA batteries. As a 12 V monobloc sealed lead-acid battery, it provides a reliable and long-lasting power solution for various application scenarios. This battery adopts a valve-regulated sealed structure and is a low-maintenance type; users do not need to regularly add electrolyte as with traditional batteries, truly achieving a convenient Maintenance Free experience. Its core advantage lies in its outstanding cycle life, reaching up to 1300 deep cycles under normal use conditions, ensuring long-term economy. The physical construction of the battery balances durability and safety. The housing is made of sturdy impact-resistant ABS plastic, effectively protecting the internal structure. The battery cover is firmly bonded to the case and specially sealed in the terminal area to prevent electrolyte leakage, achieving a leak-proof design with no free acid. Both the positive and negative plates are coated with special active material paste, and together with Absorbent Glass Mat technology, this not only improves reaction efficiency but also achieves efficient recombination of internal gases, further enhancing safety. During production, electrolyte is filled through six holes in the cover, and the subsequently installed dedicated pressure relief valve is made of non-flammable material and can automatically release internal pressure under abnormal conditions, thereby providing a high level of fire and explosion protection. In terms of installation flexibility, the EB20-12 battery performs excellently. It can be safely installed in horizontal or vertical positions, providing more possibilities for the internal space layout of equipment. Its terminal configuration is flexible: the standard configuration is a B1 Terminal Type at position 7, and users can also choose an I1 Terminal Type at position 6 to suit different connection needs. The technical parameters define its performance boundaries. The battery has a nominal voltage of 12 V, and its capacity ratings are clear: under 20-hour rate discharge conditions, the Nominal Capacity is 20 Ah; while under the higher power output 2-hour rate condition, the capacity is 15 Ah. The battery Weight is approximately 6.45 kg (14.22 lb), with compact dimensions of 181 mm (7.13 in) in length, 76 mm (2.99 in) in width, and 166 mm (6.54 in) in height, with the total height equal to the case height, making it easy to integrate into various devices. It is precisely by virtue of comprehensive advantages such as high power output capability, deep cycle tolerance, and long service life (typically up to 5-7 years) that the EB20-12 battery becomes an ideal power source for many critical devices and mobile tools. It is widely used in uninterruptible power supply systems to provide backup protection for servers and network equipment; in telecommunications facilities and medical equipment to ensure uninterrupted operation; and it is also a strong power source for mobile devices such as electric bicycles, electric scooters, wheelchairs, lawn mowers, and golf carts, meeting their strict requirements for reliable, high-cycle-performance power.
