Five-year outlook
See the shape of your battery’s future.
This interactive example shows how a five-year projection is presented. Your paid report uses measurements from your vehicle; this public tool does not test a battery.

Enter a State of Health figure to explore the shape of a projection. Your paid report models five years from measurements taken from your vehicle; this public tool does not test a battery.
Illustrative estimates
Example input — replace with your reading. This is state of health, not the current charge percentage.
- 1 pp/year assumption
- 2 pp/year assumption
- 3 pp/year assumption
Under the 2 pp/year assumption: 80% in five years.
| Year | 1 pp/year assumption | 2 pp/year assumption | 3 pp/year assumption |
|---|---|---|---|
| Today | 90% | 90% | 90% |
| Year 1 | 89% | 88% | 87% |
| Year 2 | 88% | 86% | 84% |
| Year 3 | 87% | 84% | 81% |
| Year 4 | 86% | 82% | 78% |
| Year 5 | 85% | 80% | 75% |
Interactive example only. This public tool uses simplified assumptions and your entered SOH; it does not test a battery. The paid AVILOO FLASH report produces a vehicle-specific five-year projection from measured capacity and the pack's charge and discharge behaviour. Real battery ageing may be non-linear and varies with chemistry, temperature, charging, use, software, measurement method and faults. Results may differ substantially. Do not use this tool alone to make purchase, sale, warranty, repair or safety decisions. Arrange a vehicle-specific assessment and refer to the manufacturer's guidance.
Methodology, units and sources
projectedSOH = max(0, min(100, currentSOH − annualLossPP × year))
Losses are straight-line percentage points of original capacity, not compound percentages of the current value. Units: 2 percentage points takes 90% to 88% after one year, 86% after two years, and so on.
The 1, 2 and 3 percentage-point rates are arbitrary educational scenarios chosen to bracket a simple range. They are not derived from your entered SOH, your vehicle, its chemistry, climate, mileage or charging behaviour, and no calibration factors are applied. No probability, confidence interval, best or worst case, typical rate, remaining life, replacement date, resale value or safety pass/fail is expressed or implied.
The graph demonstrates presentation shape only. The paid report's model is based on the tested vehicle's measured capacity and charge-discharge behaviour.
