Here are two common formulas to help you calculate capacity quickly: 1. Based on Current and Time: Formula: 'Capacity (Ah) = Current (A) × Time (h)' Example: If the battery is discharged at 0. Based on Energy and Voltage:. The energy density of a lithium-ion battery can be calculated using the formula: Energ Density (Wh/kg) = (Battery Rated Capaci (Ah) × Battery Average Operating Voltage (V)). This calculator is useful for determining the capacity, C-rating (or C-rate), ampere, and runtime of a battery bank or. . Usable capacity differs from total capacity: Lithium batteries provide 90-95% usable capacity while lead-acid only offers 50%. Factor in 10-15% efficiency losses and plan for 20% capacity degradation over 10 years when sizing your system.
