Tall Tubular Batteries have revolutionized electric supply systems by maintaining consultancy and providing resilience. Frequent power outbreaks across Nigeria can be easily tackled by using 220ah Tubular batteries. A 220ah Tubular Battery has the nominal capacity of 2.8 kWH, and provides power backup for approximately 2.8 hours. If you include about 2 to 3 tall tubular batteries in your inverters, you can get a consistent power supply for about 8 to 9 hours.
