I ran Tesla’s built-in battery health test on my 2025 Model Y Long Range RWD at 18 months and just over 13,162 miles — and it finished at 88% battery health. I started this series at 6 months (95%) and 12 months (90%) and planned to repeat every 6 months through the lease to see how bad this actually gets.
This video walks through the whole test: I let the car drain to 0% (fans screaming the whole time), had to restart the test because my charge limit was accidentally set to 30A, then charged overnight on my Tesla Wall Connector/UTesla adapter during my 11pm–5am off‑peak window. The car shows weird metering (it listed only ~61 kWh added at one point, Emporia recorded ~77 kWh, the car’s internal numbers settled around 73.6 kWh). Details you’ll see: ~75 battery cycles, ~6.5 MWh throughput (lifetime trip shows ~3.5 MWh driving-only), charging split ~43% AC / 57% DC, original rated range ~338 miles now ~302–307 at 100%, and cell temps cycled into the low‑90s°F during the test.
I’m honestly surprised (and annoyed) — if this trend holds we’d be near ~82% at lease end, which I don’t think is acceptable. Have you run Tesla’s battery health test? What did your Model Y or newer 2024–25 Teslas show at similar miles? Drop your results and any theory on the newer chemistry below.
