Used EV battery health & range checker
Estimate how much battery capacity a used electric car has likely lost, what that means for real-world NRCan range in summer and winter, and how much manufacturer battery warranty is left. All figures in km for Canada.

Estimated battery health
Healthy for its age
A 2024 Acura ZDX on 67,592 km, charged as “Mostly home AC charging”, would typically hold around 92.2% of its original usable capacity — roughly 39 km off the original NRCan figure.
Green ≥ 85% · Amber 75–84% · Red below 75%.
Summer range
449 km
Typical 18°C to 22°C conditions, mixed driving.
Winter range
308 km
-15°C to -5°C with cabin heating — around a 31% drop. This is the number that decides whether a used EV works for you.
Battery warranty: Active
Manufacturer battery warranty: 8 years / 161,000 km, to 70% state of health
Around 64 months and 93,342 km of cover remain, whichever runs out first. Manufacturer cover in Canada normally pays out only if health falls below 70%.
3-year degradation forecast
Assuming 14,967 km a year and the same charging habits.

What to check before you hand over any money on a used electric car in Canada.
How honest is this? These figures come from a published-average degradation model — roughly 2.2% capacity loss a year plus 0.8% per 16,093 km, adjusted for charging habits. Real packs vary widely by chemistry, climate and how the car was treated, so always confirm with a diagnostic state-of-health reading before buying.
