The median battery cost on EnergySage is $1,339/kWh of stored energy. Incentives can dramatically lower the cost of your battery system. While you can go off-grid with batteries, it will require a lot of capacity (and a lot of money!), which means most homeowners don''t go this route.
A battery is an electrical component that is designed to store electrical charge (or in other words - electric current) within it. Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge.
