How Long Do Electric Cars Last in Australia? Battery Life, Parts and the 10-Year Question

How long do electric cars last in Australia? Most will run for as long as a petrol car, and the battery is unlikely to be the thing that ends its life. Global fleet data puts average battery wear at about 2.3% of capacity a year, which leaves an EV with roughly three-quarters of its original range after a decade. Australian battery tests on used EVs show similar or better results. The bigger long-term unknowns are parts supply, software support and how well the rest of the car wears.

That matters because Australians keep their cars a long time. Passenger vehicles averaged 11.1 years old in 2024, according to BITRE figures. The Australian Bureau of Statistics’ last Survey of Motor Vehicle Use put the average at 11,100 km a year per passenger vehicle in 2019-20. At that rate, a 160,000 km battery warranty takes about 14 years to use up.

Buyers ask this most when they’re signing a long novated lease, or planning to keep a car through retirement. Here’s what the data says.

How long do electric cars last in Australia? The battery answer

An EV battery will usually outlive the car around it. Batteries don’t fail suddenly in the way a petrol engine can. They lose capacity slowly, so range shrinks a little each year.

Battery degradation is the gradual loss of how much energy a battery can store. It’s measured as state of health (SoH): the battery’s current capacity as a percentage of what it held when new. A battery at 80% SoH gives about 80% of the original range.

The largest data sets come from overseas, but Australian figures are starting to back them up:

Study	What it found	Where
Geotab, 2026	2.3% average capacity loss a year across 22,700+ EVs	Global fleet data
Recurrent, 2025	Under 4% of EVs needed a battery replacement outside recalls; 0.3% for 2022-onward cars	United States
Tesla 2023 Impact Report	Model 3 and Model Y kept about 85% after 320,000 km (200,000 miles)	Global Tesla fleet
Pickles, 2025	90.1% average battery health at 120,000 km across 250+ used EVs	Australia
NRMA and Aviloo, 2026	Most of the first 50 member cars tested sat in the normal range for their age; 15 were below it	Australia

Geotab’s figure is up from its 2024 finding of 1.8% a year. The same study linked the fastest wear to cars that rely heavily on fast charging, which is becoming more common.

Real cars show the same picture. Owners of ten-year-old Tesla Model S cars report losing a fifth to a quarter of their range. One Byron Bay chauffeur’s Model S covered 666,666 km before its first pack replacement, which was done under warranty. For a car doing 10,000 to 15,000 km a year, ten-plus years is a reasonable expectation.

What makes an EV battery wear faster

Charging habits matter most, then heat, then chemistry. Kilometres matter less than most people expect.

Fast charging. Geotab found cars that relied on DC fast charging above 100 kW lost up to 3% of capacity a year. Cars charged mainly at lower power lost about 1.5%. Charging at home on a wall box or powerpoint is the gentler option, and it’s also the cheapest.

Heat. Cars in hot climates lost about 0.4% more a year in the same Geotab study. NRMA’s 2026 battery testing noted that hotter Australian conditions, long trips and frequent fast charging all affect ageing, and that European results don’t translate directly. Liquid-cooled batteries handle heat far better than the passively cooled packs in early Nissan Leafs, which lost range badly in hot places.

Battery chemistry. LFP (lithium iron phosphate) is a battery chemistry used by BYD, the base Tesla Model 3 and Model Y, and many newer Chinese EVs. It tolerates far more full charge cycles than NMC (nickel manganese cobalt). XPeng’s Australian site quotes 3,000 to 6,000 or more cycles for LFP against 1,000 to 2,000 for NMC. Even the low NMC figure covers several hundred thousand kilometres. Our LFP vs NMC battery guide explains the trade-offs.

Sitting at 100%. Batteries age even when parked, and they age faster if left full or near empty in the heat. Our EV battery care guide covers the daily charging habits that slow this down.

EV battery warranties in Australia

Most battery warranties in Australia run for eight years or 160,000 km, whichever comes first. Most also promise the battery will keep at least 70% of its capacity during that time.

Brand	Battery warranty (as of Oct 2026)	Capacity guarantee
BYD	8 years / 160,000 km	70%
Tesla	8 years / 160,000 km (RWD) or 192,000 km (Long Range, Performance, AWD)	70%
Hyundai	8 years / 160,000 km	Not stated
Kia	8 years / 160,000 km for model year 2027 cars and EV4; 7 years / 150,000 km before that	70%
GWM	8 years / unlimited km	Not stated
Polestar	8 years / 160,000 km	70%
Zeekr	8 years / 160,000 km	Not stated
MG	7 years / 150,000 km	70%
Toyota bZ4X	8 years / 160,000 km	70%

Sources: each brand’s Australian warranty page or terms, including BYD’s 2026 warranty booklet and Kia’s warranty terms.

Read the fine print on longer headline warranties. MG offers up to ten years on the car if you service with an MG dealer, but its warranty page lists the battery separately at seven years. Toyota’s ten-year bZ4X figure is a whole-car warranty that extends with an annual battery health check, not a ten-year battery guarantee.

The 70% floor is lower than it sounds. At Geotab’s average rate, most batteries won’t get near it inside eight years. Our EV battery warranty guide explains how to make a claim.

How much a replacement EV battery costs

Replacement packs are expensive but rarely needed, and prices are falling. NRMA’s late-2025 estimates, based on global pack pricing, gave these figures for new packs before labour:

Battery size	Example car	NRMA 2025 estimate
40 kWh	Nissan Leaf	$6,622
50 kWh	BYD Atto 3, MG4	$8,278
60 kWh	Tesla Model 3 RWD	$9,933
82 kWh	Tesla Model 3 Long Range	$13,575

Real-world quotes run higher once dealer pricing and labour are added. A 2026 cost index from an Australian comparison site put typical out-of-warranty replacements at $6,000 to $20,000. The worst Australian case on record is an early Nissan Leaf, whose owner was originally quoted $33,000 in 2019 before Nissan cut the price.

Two things soften the risk. A failing pack can often be repaired by replacing individual modules rather than the whole battery, which costs far less. And the US Recurrent data suggests only a small share of modern EVs ever need a new pack. Our BYD Blade battery replacement cost guide goes into one brand in detail.

Parts, software and the rest of the car

The battery is rarely what limits an EV’s life. The questions owners worry about more are whether a screen, sensor or control unit will still be available in 2036, and whether the car will still get software updates.

Spare parts. Australia has no fixed ten-year parts rule. Under the Australian Consumer Law, manufacturers must take reasonable action to keep spare parts and repair facilities available for a reasonable time after purchase. Consumer Affairs Victoria says what counts as reasonable depends on the product. The duty doesn’t apply if you were told in writing before buying that parts wouldn’t be available.

In practice, popular models from big brands are the safer bet. A car that sells in large numbers ends up at wreckers and parts suppliers, and large carmakers have more reason to support it. Smaller or newer brands carry more risk if they leave the market or consolidate. Electric drivetrains also have fewer moving parts than petrol ones, so there’s simply less to wear out. Motors rarely fail, though it does happen. BYD covers the drive unit for the same eight years and 160,000 km as the battery.

Electronics recalls. The most widely reported weak point so far has been control electronics rather than batteries. Hyundai recalled IONIQ 5 and IONIQ 6 cars in Australia in 2024 over the integrated charging control unit, which could stop charging the 12-volt battery. Fixes were free under the recall.

Software and connectivity. Older Tesla Model S and Model X cars without an LTE modem lost app functions, navigation and live traffic when Telstra’s 3G network closed in 2024. Owners had to pay for an upgrade to get them back. Expect connected features on any car to depend on the maker continuing to support them.

Interior wear. EVs wear the same as any other car inside. Some owners of budget EVs report carpet, armrests and trim showing their age within a few years. That says more about the car’s price point than its powertrain.

Should you keep an EV for 10 years or more?

For most buyers, yes. A battery losing a couple of percent a year still leaves plenty of range for daily driving after a decade, and running costs stay low. Ten-year-old electric cars on their original batteries are already on Australian roads.

Three choices improve the odds. Pick a model with liquid battery cooling and a large sales base. Charge at home as your default, using fast charging for trips. And keep the service history, because some warranties and roadside programs depend on it.

If you’re buying used, get the battery tested first. NRMA’s battery health check costs $250 for members and $300 for non-members as of October 2026, and runs in Sydney and Canberra. The test takes a few minutes and reports remaining capacity.

Long ownership also changes the depreciation picture, which our EV depreciation guide covers. If you’re weighing a five-year novated lease, the novated lease calculator shows what the term length does to your pay. For every model on sale and its warranty, start with our electric vehicles hub.
