Product details
EVP44-12 is a 12V Valve-Regulated Sealed Lead-Acid Battery (VRLA) produced by B.B. Battery, part of the EVP series. The series offers capacities ranging from 7 to 70 Ah, with low maintenance and high cycle life as core features, specifically designed for applications requiring high power and high cycle stability. This battery adopts Absorbed Glass Mat (AGM) technology, enabling efficient gas recombination, thus ensuring complete maintenance-free operation throughout its service life, with no need for additional electrolyte additions by the user. Its structural design eliminates the presence of free acid, making it a truly leak-proof battery and providing reliable protection for the safe operation of equipment.
In terms of physical structure, the case of EVP44-12 is made of sturdy and durable impact-resistant ABS plastic. The battery cover is firmly bonded to the case, and the terminal area is sealed, resulting in excellent integrity. The six filling holes on the battery cover are used for electrolyte filling during the production process, after which a dedicated pressure relief valve made of non-combustible materials is installed. This design not only ensures high-level fire and explosion safety but also provides the battery with flexible installation characteristics, allowing horizontal or vertical installation, which greatly facilitates users.
In terms of electrical performance, the battery exhibits excellent power output and cycle capabilities.Its nominal capacity is 44 Ah at a 20-hour rate, 37.4 Ah at a 5-hour rate, and it still provides a reliable capacity of 27.5 Ah even at the high discharge rate of 30-minute rate. This characteristic of maintaining stable performance across various discharge rates enables it to meet various dynamic load requirements. The battery plates are coated with special paste-like active material, and combined with an optimized design, it can achieve a cycle life of up to 1700 cycles under normal operating conditions, ensuring a long service life and stable capacity retention.
With these comprehensive characteristics, the EVP44-12 has become an ideal power source for numerous high-demand applications.It is very suitable for uninterruptible power supply (UPS) systems and telecommunications infrastructure that require continuous and stable power supply, and can also provide safe and reliable backup power for medical equipment. Meanwhile, its high power output characteristic perfectly meets the needs of electric mobile devices such as wheelchairs, electric bicycles, scooters, and golf carts, and provides strong power for garden tools like lawn mowers. The battery dimensions are 197 mm in length, 165 mm in width, 171 mm in height, weighing approximately 15.5 kg. It is equipped with B2-type standard terminals, and other terminal types can be selected as needed to meet different connection requirements.
