We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology. The reason is related to the intrinsic qualities of lithium-ion batteries but also linked to lower transportation costs.
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
In summary, the total cost of ownership per usable kWh is about 2.8 times cheaper for a lithium-based solution than for a lead acid solution. We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology.
As expected, on a $/kWh basis, longer duration batteries have a lower capital cost, and on a $/kW basis, shorter duration batteries have a lower capital cost. Figure 7 also demonstrates why it is critical to cite the duration whenever providing a capital cost in $/kWh or $/kW. Figure 7.

Lead Acid Battery Definition: A lead acid battery is defined as a type of rechargeable battery using lead dioxide and sponge lead for the positive and negative plates, respectively, with sulfuric acid as the electrolyte.
Maintenance of Lead Acid Battery: Regularly check and maintain electrolyte levels, clean terminals, and prevent corrosion to ensure optimal performance. Safety Protocols: Implement strict safety measures, such as avoiding open flames, wearing protective gear, and maintaining proper ventilation in the battery room.
A fully charged lead acid battery cell has voltage and specific gravity, of 2.2 V and 1.250 respectively, and this cell is normally allowed to be discharged till the corresponding values become 1.8 V and 1.1 respectively. Overcharging can change the lead sulfate's properties, making it hard to convert back during charging.
If sulfation persists for a long time, it becomes hard to fix. To prevent this, charge lead acid batteries for a long time at a low charging current. Battery cell terminals are prone to corrosion, especially at the bolted connections. To prevent this, regularly check bolt tightness and cover connections with petroleum jelly.
