Product details
EP33-12 Standard Type is a high-reliability product in the EP series B.B. Battery VRLA batteries. As a sealed battery using valve-regulated lead-acid technology, it ensures maintenance-free characteristics. Users do not need to periodically add electrolyte, which greatly facilitates daily use. Its opaque, impact-resistant ABS plastic shell is sturdy and durable, effectively protecting the internal structure. The battery cover is firmly connected to the shell and sealed, and the terminal area is also well-sealed. The overall design fully takes safety and durability into account.
The core advantage of this battery lies in its high performance and long service life.It adopts Absorbent Glass Mat (AGM) technology, achieving efficient gas recombination, with no free acid inside, fundamentally eliminating the risk of leakage. Therefore, it can be safely installed and used in horizontal or vertical directions, providing high flexibility for equipment integration. Both positive and negative plates are coated with a special paste-like coating, combined with exquisite craftsmanship, enabling the battery to have high power output and excellent cycle performance. Under standard application conditions, the EP series batteries can provide up to 2000 cycles of operation, with a nominal service life of 5 to 7 years, making it a durable power solution.
In terms of electrical performance, the EP33-12 Standard Type has a rated voltage of 12V. Its capacity is clearly marked to meet different discharge rate requirements: the nominal capacity at the 20-hour rate is 33Ah, which provides a benchmark for evaluating its performance in long-duration, low-current discharge scenarios; at the 5-hour rate, the capacity is 28.05Ah; and at the 30-minute rate for high-rate discharge, it still offers 16.5Ah, demonstrating its ability to meet instantaneous high-power demands. These detailed technical parameters provide a reliable basis for engineers and users to precisely match the power source with the load.
Its physical design is compact and practical.The battery length is 195 mm, width 129 mm, height 155 mm, total height 179 mm, and weighs approximately 11.5 kg. The standard configuration includes B7-type terminals, positioned reasonably for easy connection. The six holes reserved on the battery cover are used for electrolyte filling during production. After completion, a pressure relief valve made of non-combustible material is installed, which can effectively release accumulated internal gases, ensuring high-level fire and explosion safety even under high load or abnormal conditions.
The EP33-12 Standard Type is designed for high-load cyclic applications, and its wide range of application scenarios fully demonstrate its versatility and reliability.It is an ideal choice for backup power in uninterruptible power supply (UPS) systems and telecommunication facilities, providing stable power support for key equipment. It is also widely used in various electric mobile devices such as electric wheelchairs, electric bicycles, scooters, golf carts, and lawn mowers, offering long-lasting and powerful propulsion. In fields like medical equipment with extremely high power stability requirements, its maintenance-free, leak-proof, and high-safety features make it a trustworthy power source. In summary, whether it is a fixed facility requiring continuous backup power or a mobile platform pursuing power and endurance, the EP33-12 Standard Type can provide efficient, safe, and long-lasting electrical energy support.
