This article presents a new method for determining the effective capacity of a lead-acid battery by applying the least squares theory. Power supply of an isolated power grid can be achieved with a mix of sources, among which the most affordable are solar energy, wind power and fossil fuels. In these cases, the final price of the electricity obtaine...
