Electric or hybrid? Comparing used cars on everyday use, battery and maintenance

Key takeaways

A used electric car makes sense if you can charge regularly at home or at work. There are no oil changes, spark plugs or exhaust repairs. In winter, though, expect a range 11–32% shorter than the WLTP figure.
A full hybrid is the choice for drivers with nowhere to charge. Its small battery (1.32 kWh in the Kia Niro Hybrid) is recharged by the car itself, and the battery's condition affects how usable the car is less than it does in an electric car.
A plug-in hybrid only makes sense with regular charging. In real-world driving in 2024, plug-in hybrids used 2.8 l/100 km even in the mode in which they ran on battery power.
Electric car batteries lose an average of 2.3% of their capacity a year. Warranties differ: Kia covers a drop in capacity below 70% for 7 years or 150,000 km (models up to model year 2025), while Toyota covers the hybrid system for 5 years or 100,000 km.
Carvago offers tens of thousands of used electric cars and inspects every car as part of CarAudit™ before sale. For some electric cars, the battery health (SOH) or a battery certificate is also shown directly in the listing.

Electrified cars come in three types, and the only thing they share is a traction battery. An electric car runs purely on electricity. A full hybrid is filled up with fuel and generates its own electricity. A plug-in hybrid is both filled up and charged from a socket. If you are buying used and weighing up an electric car against a hybrid, the fuel or energy consumption in the listing is not the only thing that matters. What counts is where you will charge, how long your journeys are and what condition the battery of the specific car is in.

Electric or hybrid: what you are actually buying

A full hybrid (HEV) has a small battery. Its job is to let the electric motor work together with the combustion engine. It gets its electricity from regenerative braking and from the combustion engine, and it does not plug in. A plug-in hybrid (PHEV) has a battery roughly ten times larger, is charged externally and can handle normal local driving on electricity. It still has a combustion engine, though, and that engine still needs servicing. An electric car (BEV) has no combustion engine at all.

Which drivetrain suits your journeys and charging

You can charge at home or at work: electric car

An electric car suits drivers who charge while the car is parked anyway: overnight in a garage or during working hours. You then never have to make a special trip to a charger. With a used car, a battery that covers your usual journeys with a winter reserve is enough. There is no need to overpay for the biggest possible capacity. Specific models by use are covered in our article on the best electric car.

On longer journeys, an electric car needs charging stops. How long they take varies considerably between models: according to the manufacturer, the Hyundai Ioniq 5 charges from 10 to 80% in 18 minutes on a suitable rapid charger, while older and smaller models take noticeably longer. Allow for winter, too. In a winter road test of 31 electric cars, range was 11–32% shorter than the WLTP figure. The details are covered in the articles on electric car range in winter and on how to compare electric cars.

You have nowhere to charge: full hybrid

A full hybrid is electrification without the hassle of charging. In town and in queuing traffic, it recovers energy every time it slows down and can cover part of the journey with the combustion engine switched off, so that is where it saves the most. On the motorway at a steady speed, it runs mostly on petrol and its advantage shrinks.

With a used hybrid such as the Toyota Corolla Hybrid or the Kia Niro Hybrid, you are therefore not dealing with charging or range, but above all with the service history of the whole car. Moderate wear of the small battery tends to show up as slightly higher consumption rather than as a limit on how the car can be used. What to focus on with a second-hand hybrid is summarised in the section on what to watch out for below.

You charge regularly and want petrol as a back-up: plug-in hybrid

A plug-in hybrid pays off if you cover most of your everyday journeys on electricity and long trips are the exception. Charging has to be a daily routine. In our view, buying a PHEV on the assumption that you will sort out charging "some time later" is the quickest route to disappointment.

With a flat battery, a PHEV carries on as a hybrid, just with hundreds of kilograms of extra hardware on board. The Škoda Octavia iV 1.4 TSI (150 kW) has a battery with a gross capacity of 13 kWh. A plug-in hybrid is therefore not a compromise without drawbacks: you get two drivetrains, but also the maintenance of both.

What is the real-world fuel consumption of a plug-in hybrid

A PHEV's fuel consumption tells you little on its own. A low figure in l/100 km often just means that the battery supplied much of the energy, and you paid for that in the price of electricity. So include both in your running costs.

Real-world data shows that even a charged battery does not guarantee driving without petrol. According to an analysis by the European organisation Transport & Environment, plug-in hybrids in 2024 used an average of 2.8 l/100 km in charge-depleting mode, on top of electricity. The combustion engine kicks in under harder acceleration, at higher speeds or in winter for heating. Once the battery is flat, a PHEV runs on petrol alone and its consumption approaches that of a conventional hybrid, but with more weight.

The rule for a used-car buyer is simple: choose a plug-in hybrid according to how often you will charge it, not by the lowest consumption figure in the listing.

How electric car and hybrid batteries age

All three drivetrains have a traction battery, but its condition carries different weight for each:

Car	Battery capacity	What a loss of capacity means
Kia Niro Hybrid 1.6 GDi	1.32 kWh	Less electric assistance, higher consumption
Kia Niro Plug-in Hybrid 1.6 GDi	11.1 kWh	Shorter electric range
Škoda Octavia iV 1.4 TSI (150 kW)	13 kWh gross, 10.4 kWh usable	Shorter electric range
Volkswagen ID.3 Pro Performance	62 kWh gross, 58 kWh usable	Shorter range for the whole car

The difference between gross and usable capacity does not mean wear. The manufacturer keeps part of the battery in reserve to protect it from being fully charged or fully discharged.

How much capacity a battery loses each year

According to a study by Geotab covering more than 22,700 electric cars, batteries lose an average of 2.3% of their capacity a year. As a rough guide, an average five-year-old car has therefore lost a little over a tenth of its capacity. That is a long way from the threshold at which a capacity warranty kicks in. Individual cars differ from the average in both directions, though, which is why with a used car, a measurement of the specific battery is worth more than statistics. Neither the mileage nor the range estimate on the display reflects the battery's condition, because the display also takes previous driving style and temperature into account.

State of health (SOH) is established by measuring the battery itself. For cars on Carvago, the CarAudit™ inspection checks the technical condition, and for some electric cars the battery health (SOH) or a battery certificate is shown directly in the listing.

A full hybrid's battery operates only within a narrow state-of-charge window and usually ages slowly. If it does weaken, the result is higher consumption and the combustion engine running more often, not a car that stops working.

What a battery warranty covers

A defect warranty and a capacity warranty deal with different situations. The first applies when the battery or drivetrain fails. The second sets how far capacity may drop before you are entitled to a repair or replacement.

Example warranty	Period and mileage	What it covers
Toyota Corolla Hybrid	5 years or 100,000 km, whichever comes first	Defects in the hybrid system, including the traction battery
Kia, electric cars and plug-in hybrids up to model year 2025	7 years or 150,000 km	Battery capacity falling below 70% of the original value

For models from model year 2026, Kia extends the battery warranty to 8 years or 160,000 km. A manufacturer's warranty stays with the car, but it usually depends on the service schedule having been followed. With a used car, you therefore need to know not only how much time and mileage is left, but also whether the previous owner met the conditions. A good battery and a valid warranty are two separate advantages, and one does not replace the other.

Which drivetrain needs the least maintenance

An electric car needs the least servicing. Škoda states that an electric motor has lower maintenance requirements than a combustion engine. Brakes, suspension, tyres, air conditioning and the battery cooling circuits still need attention, though.

Maintenance area	Electric car	Full hybrid	Plug-in hybrid
Combustion engine	None	Oil, filters and other items according to the service schedule	Same as any other combustion engine
Electrical system	Battery, power electronics, cooling, charging	Battery, power electronics, cooling	Battery, power electronics, cooling, charging
Brakes	Regenerative braking spares the pads, but the discs corrode when little used	Same principle	Same principle
What it means for a used car	Fewer routine items, but the risk of one expensive repair	Care of both the engine and the hybrid system is decisive	Care of both drivetrains is decisive

In a plug-in hybrid, the combustion engine may cover very few kilometres. Time-based service intervals still apply, though. Frequent short cold starts are not good for the engine either. The greater complexity of a PHEV does not mean every model is less reliable. When you buy one, however, you take on the condition of more components.

How running costs and resale value differ

Purchase price, energy, servicing and the eventual sale form a single whole, as our overview of car running costs also shows. An electric car saves on servicing and, with cheap home charging, on energy as well. Part of that advantage can, however, be swallowed by a higher purchase price or faster depreciation. With a plug-in hybrid, the benefit of electric driving disappears if you only charge occasionally.

Resale value is determined by supply, demand and buyer preferences. With electric cars, the rapid development of new models plays a part too: with each generation, range and charging speed improve, so older models lose their appeal faster. For a used-car buyer, that is an advantage, because for a fraction of the original price you get a car that still does its job well. When you come to sell, a documented service history and a battery test result help with all three drivetrains.

What to watch out for with a used car

Mistaking a full hybrid for a plug-in hybrid. The word "hybrid" in a listing tells you nothing. You cannot charge an HEV from a socket, and a PHEV loses its main advantage without charging.
Relying on the display instead of a measurement. The range estimate reflects previous journeys and the temperature; you cannot read the battery's condition from it. Only a battery test gives a reliable picture.
Faulty charging equipment. With an electric car or a PHEV, the inspection should include the charging socket, the cable and the on-board charger. Repairs are not cheap, and no listing will mention them.
Incomplete service history on a hybrid. The combustion engine in a hybrid or PHEV needs the same servicing as in a conventional car, even if it has covered few kilometres.
Overrating the warranty. A remaining warranty is no substitute for knowing the battery's current condition, and it only applies if the manufacturer's conditions have been met.

Electric or hybrid via Carvago: inspection, battery test and warranty

Carvago has the widest selection of used electric cars: tens of thousands of cars from dealers in several European countries. The selection shown varies from country to country. That means you can choose a car to suit your journeys and charging options, rather than settle for whatever the local market happens to offer.

Before sale, a technician inspects every car as part of CarAudit™, which has up to 270 checkpoints. The inspection covers the car's available history and legal status, its technical components, diagnostics and a test drive. You see the result before you decide to buy, and Carvago guarantees the condition stated in the certificate. For some electric cars, the battery health (SOH) or a battery certificate is shown directly in the listing. For such cars, you are therefore not paying for a battery whose condition you know nothing about.

Before the sale, Carvago buys the car from the original seller, becomes its owner and takes on the risks. You therefore buy directly from Carvago. Every car also comes with a free extended warranty, which is particularly useful for a car whose manufacturer's warranty is running out.

FAQ

Is a mild hybrid the same as a full hybrid?

No. A mild hybrid has a small electric motor that only assists the combustion engine and cannot move the car on its own. Do not expect the savings or electric driving of a full hybrid from it.

Do electric cars and hybrids also have a normal 12 V battery?

Yes. Alongside the traction battery, they also have a low-voltage system. If the 12 V battery is weak, the car may not start, even if the traction battery has plenty of energy.

Can a plug-in hybrid be charged at a rapid charger?

Mostly not. Most plug-in hybrids can only be charged with alternating current from a wallbox or a socket, and only some models support DC rapid charging. For a PHEV, charging at home or at work is therefore practically a must.

Can a plug-in hybrid keep running on petrol if the traction battery fails?

Do not count on it. The two drivetrains form one interconnected system, and some faults in the high-voltage system will immobilise the car. Driving with a flat battery is not the same as driving with a faulty one.
