NPP NPD2-300Ah 2V 300Ah AGM VRLA Deep Cycle Battery

NPP NPD2-300Ah 2V 300Ah AGM VRLA Deep Cycle Battery

The NPP NPD2-300Ah Deep Cycle battery is a 2-volt, 300 amp-hour sealed AGM VRLA battery designed for dependable cyclic and standby performance in industrial and renewable energy applications. Built with thicker plates and enhanced active material, this deep cycle model offers improved discharge recovery and longer cycle life compared to general-purpose AGM cells. Its maintenance-free and spill-proof construction allows for safe installation in enclosed battery cabinets and indoor systems.

Engineered for durability and consistent performance, the NPD2-300Ah is ideal for solar energy storage arrays, telecommunications infrastructure, UPS systems and industrial backup power banks. The rugged ABS housing and absorbed glass mat technology ensure low internal resistance, stable voltage output and reliable performance during repeated charge and discharge cycles.
