Product details
The MSU-400 series battery focuses on industrial-grade reliability, achieving a nominal capacity of 400Ah (C10 discharge rate) within a 2V voltage framework, meeting the deep charge-discharge needs of power networks and renewable energy systems. The battery employs a dual paste coating process for positive and negative plates, combined with a special alloy formulation, extending float service life to 18 years, far exceeding the Eurobat long-life standard. The compact 24.5kg design (174mm × 174mm × 360mm) is compatible with standard I3B6 terminals, allowing flexible assembly into battery packs of different voltages to provide stable power support for medical emergency equipment or security monitoring systems.Its innovative gel electrolyte immobilization system effectively prevents stratification, maintaining over 95% charge acceptance efficiency even in wide temperature ranges from -20°C to 50°C. The pressure relief valve module utilizes aerospace-grade flame-retardant materials, ensuring intrinsic safety protection in flammable scenarios such as oil and gas extraction. The accompanying three-dimensional installation solution saves space for power deployment in rural base stations and smart buildings. From EV charging piles to hotel emergency lighting, the MSU-400, with its 54-pound lightweight structure (including terminals) and maintenance-free features, has become the preferred cross-domain energy solution.Product Features
