Battery Capacity Fade Calculator
Use Battery Capacity Fade to the remaining capacity calculation. The loaded example shows the arithmetic with practical electrical units.
Enter values for remaining capacity
Use one consistent electrical operating case for all fields.
How Battery Capacity Fade works
The stated formula is remaining = initial × (1 − fade). Battery Capacity Fade uses Initial capacity, Capacity fade to report Remaining capacity. Use Battery Self-Discharge Calculator to a separate capacity remaining calculation.
With the loaded values, remaining capacity evaluates to 82.00 Ah. Retain the initial result as the comparison baseline.
Inputs for Battery Capacity Fade
Initial capacity and Capacity fade belong to Battery Capacity Fade. Keep source units with initial capacity.
No recommendation is implied by the loaded example. Use measurements from the intended scenario.
- Initial capacity
- Example entry: 100 Ah.
- Capacity fade
- Example entry: 18%.
Reading the Battery Capacity Fade result
This output represents Battery Capacity Fade.
A computed value still needs comparison with standard equipment ratings and operating limits.
Measurement and units
Battery calculations depend on chemistry, temperature, age, discharge rate, and the limits of the battery management system. Check prefixes on initial capacity.
Preserve the measurement basis when testing alternatives.
Limits of this calculation
Fade is not always linear with time or cycles. Use Battery Specific Power Calculator.
Treat the formula as one part of the overall electrical analysis. Unentered effects remain outside Battery Capacity Fade.
Battery Capacity Fade record notes
Record source and operating details for initial capacity. Continue to Peukert Battery Runtime Calculator for peukert runtime.
Retain raw remaining capacity beside its selected rating.
