Battery Degradation Estimator
Estimate Li-ion battery capacity loss based on cycles, DoD, and temperature. Enter values for instant results with step-by-step formulas.
Worked Examples
Example 1: Careful Usage
Problem: NMC Battery, 500 Cycles, 40% DoD, 25°C
Solution: Low stress. Loss ~3-4%.
Result: 96% Remaining
Example 2: Heavy Usage
Problem: NMC Battery, 500 Cycles, 100% DoD, 40°C
Solution: High stress. Loss ~10-12%.
Result: 88% Remaining
Frequently Asked Questions
Is degradation linear?
Not exactly. It typically has a 'knee' curve—slow degradation for a long time, then a rapid drop-off near end-of-life.
Can I reverse degradation?
No. It is a chemical change (loss of active lithium inventory). You can only slow it down.
How do I verify Battery Degradation Estimator's result independently?
The Formula section on this page shows the equation used. You can reproduce the calculation manually or in a spreadsheet using those steps. Compare your answer against the worked examples in the Examples section, which use known reference values so you can confirm the calculator is behaving as expected.
What inputs do I need to use Battery Degradation Estimator accurately?
Each field is labelled with the required unit (metric or imperial). Gather your source values before starting — for example, a weight measurement in kilograms, a distance in metres, or a dollar amount — and enter them exactly as measured. The formula section on this page lists every variable and explains what each represents.
Can I use Battery Degradation Estimator on a mobile device?
Yes. All calculators on NovaCalculator are fully responsive and work on smartphones, tablets, and desktops. The layout adapts automatically to your screen size.
Can I use the results for professional or academic purposes?
You may use the results for reference and educational purposes. For professional reports, academic papers, or critical decisions, we recommend verifying outputs against peer-reviewed sources or consulting a qualified expert in the relevant field.
