Valve Regulated Lead Acid Battery



The HR (High Rate) Series is designed specifically for high rate applications, including high rate UPS/EPS systems and power switchgear applications.
By using strong grids and specially designed active material, the HR Series batteries ensure stable performance during high current discharge. They offer very high power output at 15 min backup time with 5 ~ 12 years design life.
