The price per kWh for lead acid batteries typically ranges in real projects from about $70 to $210 per kWh, with a total system cost often landing between $110 and $350 per kWh when installation and ancillary items are included. This article breaks down pricing from raw cell costs to installed system totals, using ranges in USD to reflect regional and project differences. Buyers typically pay a per kWh price that scales with the size of the pack. . In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration systems. The projections are developed from an analysis of recent publications that include utility-scale storage costs. What is Commercial Battery Storage? Commercial battery storage involves using batteries to store. . In 2025, the typical cost of a commercial lithium battery energy storage system, which includes the battery, battery management system (BMS), inverter (PCS), and installation, is in the following range: $280 - $580 per kWh (installed cost), though of course this will vary from region to region. . The most common types of commercial batteries include lithium-ion, lead-acid, and flow batteries. Lithium-Ion Batteries: Known for their high energy density and efficiency, lithium-ion batteries are popular but can be more expensive upfront.
