NPL12-150

Series Introduction：

The NP-L series batteries developed by Yuantai adopt special corrosion-resistant alloys and a grid structure with 3D curved surface design. The ultra-thick plate design features a positive plate thickness of 3.7mm, which is 30-40% thicker than ordinary plates. Combined with electrolytes of lower density, they exhibit excellent floating charge performance, with a designed floating charge service life of over 12 years, making them suitable for various application scenarios requiring floating charge operation.
