A battery plays a vital role in the life of an inverter. In the situation of a power cut, we need to have some stored electricity that we can use to run our appliances. A battery is where we can store that extra electricity. This stored electricity is in the form of DC power and an inverter helps us to use this stored power by converting it into AC power. We can connect two broad types of batteries with inverters. Lead Acid type and Tubular type batteries. There are essentially rechargeable wet batteries. Batteries need maintenance and can create problems if not taken care of and for doing that the first thing would be to know your battery inside out!
