Renewable Energy SLR Battery Series
GS Yuasa
Lead Acid Batteries
VRLA (AGM) 2V Cells
PRODUCT DESCRIPTION
The SLR Series is designed for high cycle applications using GS Yuasa’s Advanced Lead Nanocarbon battery technology. A Nanocarbon additive accelerates the reaction of active material to reduce sulfation. This leads to increased charging efficiency, exceptional PSOC performance, and higher capacity retention over the battery life. The product utilizes GS Yuasa’s HT Element X™ for high heat, long life performance. The SLR product line provides 19 years cycle life when tested to IEC 61427. The product is suitable for back-up applications as well as deep cycle.
