Product details

The EVP44-12 belongs to the EVP series of valve-regulated lead-acid batteries and is supplied in a 12 V monobloc format, with a nominal capacity of 44 Ah at the 20-hour rate, which supports equipment that needs a steady backup supply. The battery uses absorbent glass mat (AGM) technology to achieve efficient gas recombination and is maintenance free (no water addition required) throughout its service period, so users never need to add electrolyte. Internally there is no free liquid acid, and the leak-proof construction improves safety and convenience in use. The battery can be installed horizontally or vertically (an inverted position is not allowed), which gives flexibility for layout inside equipment. The case is made of sturdy, impact-resistant ABS plastic, the cover is firmly joined to the case, and the terminal area is sealed to help prevent corrosion and leakage. Six holes in the cover are used to fill electrolyte, after which a pressure relief valve made of non-combustible material is installed together with an explosion-proof filter and a flame arrestor to raise fire and explosion safety. Both the positive and negative plates carry a specially formulated paste active material, and the optimized grid design together give the battery high power output and a long cycle life. In technical terms, besides the 44 Ah capacity at the 20-hour rate, the capacity is 37.4 Ah at the 5-hour rate and 27.5 Ah at the 30-minute rate, which reflects its ability to deliver a large current over a short period. The battery weighs 15.5 kg and is compact enough to integrate into many types of equipment. Terminal configuration is flexible: B2 terminals are standard, while I1 or I2 terminals can be selected to meet different wiring requirements. The EVP44-12 covers several key fields. As a storage unit for uninterruptible power supply it can keep power flowing for data processing centers, financial trading systems, and industrial control equipment. In communication facilities it supplies stable power for base stations and communication equipment. Medical equipment such as monitors and diagnostic instruments depends on its reliable power for precise operation. In electric wheelchairs, golf carts, electric lawn mowers, electric bicycles and scooters, electric vehicles, and floor cleaning equipment, the battery provides ample power and cycling performance for frequent use. Overall, the EVP44-12 is a leak-proof, maintenance free battery designed for high-power, high-cycle applications, balancing durability, safety, and applicability.
