An inverter battery is designed to provide a small amount of current for a longer duration of time. All the power backup solutions, like inverters, and UPS operate by converting the DC current into AC current as all of our electrical appliances run on AC power. Difference between inverter and battery stores the energy in the form of the DC. The inverter helps in storing the AC power coming from the source in the batteries. The battery stores the current in the form of DC which is again converted into AC with the help of an inverter and supply to the home appliances. They are used in smart devices, mobile phones, and some other appliances. Lead Acid Batteries: These types of batteries are used in non-portable appliances due to their heavy size. They are used in vehicles, inverters, solar-panel energy storage devices.
