mAh (milliamp-hours) and Ah (amp-hours) are both units of capacity used to measure battery storage, with mAh being a smaller unit (1 Ah = 1,000 mAh). mAh is typically used for smaller devices like smartphones and cameras, while Ah is more common for larger batteries such as those used in cars or solar power systems.
It can be compared to the nameplate rating of a power plant. Power capacity or rating is measured in megawatts (MW) for larger grid-scale projects and kilowatts (kw) for customer-owned installations. Energy storage capacity: The amount of energy that can be discharged by the battery before it must be recharged.
Grab a bunch of cells of that make, weigh them, find a typical number for AH per gram. For A123 I get 0.035 AH/Gram for their 20AH pouch cells, 0.033 for their cylinder cell.
How to Calculate Battery Capacity? 1.Identify the Battery Specifications. To calculate the battery capacity, you first need to find its specifications.

The need for energy storage. Energy storage—primarily in the form of rechargeable batteries—is the bottleneck that limits technologies at all scales. From biomedical implants and portable electronics to electric vehicles [3– 5] and grid-scale storage of renewables [6– 8], battery storage is the primary cost and design limitation
“The first gas plant knocked offline by storage may only run for a couple of hours, one or two times per year,” explains Jenkins. “But the 10th or 20th gas plant might run 12 or 16 hours at a stretch, and that requires deploying a large energy storage capacity for batteries to reliably replace gas capacity.”

Beyond rebates and incentives, energy storage can also provide financial benefits by helping to defray costs on your electricity bills. If you are on a time-of-use rate, energy storage can help lower your electricity bill by charging your battery when electricity prices are low and pulling from your battery–instead of from the grid–when electricity prices are high.
Using the detailed NREL cost models for LIB, we develop base year costs for a 60-MW BESS with storage durations of 2, 4, 6, 8, and 10 hours, shown in terms of energy capacity ($/kWh) and power capacity ($/kW) in Figure 1 and Figure 2
Understanding how to calculate battery capacity is crucial for optimizing the performance and lifespan of your batteries. The capacity, often measured in milliampere-hours (mAh), represents the energy storage capability of a battery.
For example, a battery with a capacity of 1000 mAh and a voltage of 3.7 volts would have an energy storage capacity of 3.7 watt-hours (Wh). To calculate the total capacity of batteries in a series-parallel configuration, you need to first calculate the capacity of each parallel group, and then add up the capacities of each group.

Total System Cost ($/kW) = (Battery Pack Cost ($/kWh) × Storage Duration (hr) + Battery Power Capacity (kW) × BOS Cost ($/kW) + Battery Power Constant ($)) / Battery Power Capacity (kW) For more information on the power versus energy cost breakdown, see (Cole and Frazier, 2020).
Capacity, expressed in WH refers to the total amount of energy that can be stored in the battery at full charge. For instance, a battery discharged at a lower depth lasts longer however, the implication is that the available and useable watt or Amp hours (Ah) of the battery life may reduce.
Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2021). The bottom-up BESS model accounts for major components, including the LIB pack, inverter, and the balance of system (BOS) needed for the installation.
To calculate the true energy storage costs (as against up-front price point) and benefits of any battery system, calculate the obtainable lifetime hours in watt and include the other costs connected with setting up operation and replacement eventually.
It is a philosophical choice how to present battery costs. You can add all of the cost lines together (in $) and divide them by the total power rating in kW (yielding a $/kW metric).
