Product details
For applications requiring a stable and reliable backup power source, the EVP44-12EVP series valve-regulated lead-acid battery provides an excellent solution. This battery is provided in a 12-volt form, with a nominal capacity of 44 ampere-hours at a 20-hour rate, ensuring long-lasting and powerful power support for various devices. It uses absorbent glass fiber separator technology, achieving efficient gas recombination, making the battery completely maintenance-free throughout its service life, and users do not need to worry about adding electrolyte.At the same time, the battery contains no free acid inside and is designed as a leak - proof structure, significantly enhancing the safety and convenience of use. It allows horizontal or vertical installation and use, providing high flexibility for users in the layout within the equipment.
The battery case is made of sturdy and impact - resistant ABS plastic. The battery cover is firmly attached to the case, and the terminal area is sealed to effectively prevent corrosion and leakage. During production, electrolyte is filled through six holes on the battery cover, followed by installing a pressure relief valve made of non - combustible materials. This design not only ensures a high level of fire and explosion safety but also reflects the product's extreme pursuit of safety.Both positive and negative plates are coated with specially formulated paste - like active materials. Along with an optimized grid design, they collectively endow the battery with excellent high - power output characteristics and a long cycle life. Under typical general usage conditions, EVP series batteries can provide up to 1700 deep cycles, with an expected service life of 5 to 7 years, making it an ideal choice for users pursuing long - term investment returns.
Its extensive application scenarios cover multiple key areas of social production and life. As the core energy storage unit of uninterruptible power supply systems, it ensures uninterrupted power supply for data centers, financial transaction systems, and industrial control equipment. In telecommunications facilities, it provides stable power for base stations and communication equipment, ensuring unimpeded signal transmission.Medical devices such as monitors and diagnostic instruments rely on its pure and reliable power to maintain precise operation. Additionally, in personal mobility aids such as electric wheelchairs and golf carts, gardening tools such as electric lawnmowers, and even popular personal transportation vehicles like electric bicycles and scooters, the EVP44-12 battery can provide ample power and excellent cycle performance, meeting the needs of high-frequency use.
From the specific technical parameters, in addition to the 20-hour rate capacity of 44 Ah, its 5-hour rate capacity is 37.4 Ah, and the high-rate discharge capacity at the 30-minute rate can still reach 27.5 Ah, which demonstrates its excellent instantaneous high-current discharge capability. The battery weighs approximately 15.5 kg, compact structure, external dimensions of 197 mm (length) × 165 mm (width) × 171 mm (height), facilitating integration into various devices. The terminal configuration is flexible, with standardly equipped type B2 terminals at position 7. Additionally, type I1 or I2 terminals can be optionally selected according to customer requirements to meet different wiring needs. In conclusion, the EVP44-12 is a leak-proof and maintenance-free battery designed specifically for high-power and high-cycle applications. It perfectly combines durability, safety, and applicability, making it a reliable cornerstone for modern backup and power supply applications.
