The WK-FT series valve-regulated sealed lead-acid batteries are front-terminal valve-regulated batteries specially designed for 19-inch and 23-inch power cabinets in communication systems. They adopt high-tin low-calcium alloys, AGM valve-regulated technology, and efficient gas recombination principles, successfully achieving battery sealing and maintenance-free operation. The batteries have a long service life, including: Two series of products, FTA and FTB.

Generally, four batteries form a 48V system. The positive and negative terminal connections and exhaust holes are located at the front of the battery, which is convenient for installation, maintenance and measurement, and saves space. The central exhaust system can discharge the gas generated inside the battery to the battery room, improving the safety and reliability of the system.
