- Tesla Model 3A used Model 3's battery health depends on which pack it has — Australia has seen 52.5 to 79 kWh usable across six variants. What SoH is normal, what isn't, and how to tell.Verified 2026-09-13
- Tesla Model YModel Y battery health varies by pack and generation, and Australian real-world testing shows the Long Range AWD using 16.7 kWh/100km. What to check on a used one.Verified 2026-09-13
- BYD Atto 3Australian real-world testing found the Atto 3's claimed range overstated by 23% — the largest gap of any EV tested. What that means for battery health, and what to check used.Verified 2026-09-13
- Nissan LEAFThe LEAF's passively-cooled pack degrades faster than most EVs, and Nissan measures its warranty in bars rather than percentages. On a used LEAF, the individual car matters more than the model.Verified 2026-09-13
- BYD SealThe BYD Seal's 82.5 kWh Blade pack is one of the more durable batteries on the Australian market. Here's what State of Health is normal, and what still needs checking on a used one.Verified 2026-09-13
- MG4The MG4 has been sold in Australia with 51, 64 and 77 kWh packs, and MG publishes no minimum State of Health at all. That makes measuring it more important, not less.Verified 2026-09-13
- Polestar 2Polestar is one of few brands to write "State of Health" into its warranty with a 70% floor. Here's what's normal on a used Polestar 2, and which of six Australian variants you're looking at.Verified 2026-09-13
- Hyundai IONIQ 5The IONIQ 5 has been sold in Australia with 54, 74 and 80 kWh usable packs — and Hyundai publishes no minimum capacity percentage at all, unlike Kia. What to check on a used one.Verified 2026-09-13
- Kia EV6The EV6 has a 70% capacity guarantee Hyundai's IONIQ 5 doesn't — but Kia caps pre-2027 cars at 150,000 km. What's normal, and what to check on a used one.Verified 2026-09-13
- Hyundai Kona ElectricThe Kona Electric has been sold in Australia with 39, 48, 64 and 65 kWh usable packs across two generations. What's normal for each, and why Hyundai's warranty won't help with degradation.Verified 2026-09-13
- MG ZS EVThe MG ZS EV has been sold in Australia with 42.5, 49 and 68.3 kWh usable packs — and MG publishes no minimum State of Health. What to check on a used one.Verified 2026-09-13
- Volvo EX30The EX30's 65 kWh pack is well-managed and should age predictably. Volvo's position on capacity guarantees, however, differs between two of its own official pages.Verified 2026-09-13
- BYD DolphinThe Dolphin's Blade LFP pack is durable, but Australia got 44.9 and 60.5 kWh versions and the smaller one has little range to spare. What's normal and what to check.Verified 2026-09-13
- Toyota bZ4XThe bZ4X is sold as 71.4 kWh but only 64 kWh is usable. Toyota guarantees 70% for 8 years — unless the car was used commercially. What to check on a used one.Verified 2026-09-13
- Volkswagen ID.4Volkswagen is the only manufacturer publishing a stepped capacity guarantee — 78% at 3 years, 74% at 5, 70% at 8. That lets you judge an ID.4 against VW's own expectation, years early.Verified 2026-09-13
- Cupra BornThe Born shares the ID.4's 77 kWh pack and Volkswagen's stepped 78/74/70% capacity guarantee. What's normal on a used one, and what to check.Verified 2026-09-13
- Hyundai IONIQ 6The IONIQ 6 is among the most efficient EVs sold in Australia, but Hyundai publishes no capacity floor. What's normal on a used one, and one consumption figure to treat carefully.Verified 2026-09-13
- GWM OraGWM gives private owners 8 years with unlimited kilometres and a 70% floor — the only brand that does. But the Ora came with 45.4 and 59.3 kWh packs and the small one is tight.Verified 2026-09-13
- Mini Cooper SEThe Cooper SE's warranty stops at 100,000 km, 60,000 km before BMW's. On a commuter car that limit usually arrives before the 8 years do. What to check on a used one.Verified 2026-09-13
- Lexus UX 300eThe UX 300e is sold as 54.3 kWh but only 45 kWh is usable — a 17% gap, the largest of any EV we hold data for. Any range calculation on the headline figure is badly wrong.Verified 2026-09-13
- Kia EV3The EV3 is one of few Australian EVs with a measured real-world consumption figure, and Kia guarantees 70% capacity. What's normal on a used one and what to check.Verified 2026-09-13
- Kia Niro EVThe Niro EV sits on similar mechanicals to the Hyundai Kona Electric but gets Kia's 70% capacity floor, which Hyundai doesn't publish. What's normal on a used one.Verified 2026-09-13
- Polestar 4The Polestar 4 carries one of the largest packs sold in Australia at 94 kWh usable, with a warranty that names State of Health and a 70% floor. What to check on a used one.Verified 2026-09-13
- BYD Sealion 7The Sealion 7's Blade LFP pack is durable, and one Australian owner figure over 30,000 km gives a genuine real-world consumption number. What to check on a used one.Verified 2026-09-13
- Volvo XC40 RechargeThe XC40 Recharge was sold in Australia with 66, 75 and 79 kWh usable packs. Volvo's own two pages disagree on whether capacity is guaranteed. What to check used.Verified 2026-09-13
- BMW i4BMW covers the i4 battery for 8 years or 160,000 km but publishes no capacity percentage — only "excessive capacity loss", undefined. What that means when you're buying used.Verified 2026-09-13
- Mercedes-Benz EQAThe EQA is covered for 8 years or 160,000 km under Mercedes' EQ Owner Protection Plan, with no published capacity guarantee. What's normal on a used one and what to check.Verified 2026-09-13
- BMW iX1The iX1 uses the same 64.7 kWh usable pack as the Mini Countryman SE but gets BMW's 160,000 km cover rather than Mini's 100,000 km. What to check on a used one.Verified 2026-09-13
