Car battery replacement: when, which battery and what it costs
A car that starts slowly in the morning often has a weak battery (in Dutch: accu). That does not mean you need to replace the battery straight away. This article explains how long a battery lasts, how to tell when it is worn out, which battery a car with a start-stop system needs and what to look out for when it is replaced.

The short answer
According to the ANWB, the Dutch motoring organisation, a car battery lasts three to six years, sometimes longer. If your car starts with difficulty, have the battery tested before you replace it. A car with a start-stop system needs an AGM or EFB battery, and on many modern cars the new battery has to be registered in the car’s system if the manufacturer requires it. According to the ANWB, a new battery costs € 100 to € 300, depending on the type, and at our garage you receive a quote in advance based on your registration number.
How long does a car battery last?
According to the ANWB, a car battery lasts three to six years, and sometimes longer. How long your battery keeps going depends on how you drive and where the car is parked. A battery is a wear part. It slowly gets weaker, even if you do not notice it.
According to the ANWB, these conditions are harder on the battery:
How can you tell the battery needs replacing?
An important sign is that the car starts with difficulty. According to the ANWB, that can point to a worn battery. Also look out for these signs:
If the car will not start at all, the cause may also lie somewhere else. Read what you can do on our page car won’t start.
Why have the battery tested first?
A test shows whether the battery is really worn out or only flat. That difference matters. A flat battery can be recharged. A worn battery no longer holds its charge. According to the ANWB, a battery can be measured and replaced if necessary.
During a battery test in our workshop, the mechanic measures how much starting power the battery still delivers. He also checks whether the alternator is charging the battery properly. That way we avoid you buying a new battery when the cause lies somewhere else.
| When | What we do with the battery |
|---|---|
| Minor service | We check the battery. |
| Major service | We test the battery with a battery tester. |
| Separate battery test | We measure the starting power of the battery and check whether the alternator is charging properly. |

Autumn is a good time for a test. A battery that still starts the car well in October can give up at the first frost. That is why the battery is at the top of our checklist for getting your car ready for winter. Planning to drive abroad this winter? Also read the winter tyre rules in the Netherlands and abroad.
Which battery does a car with a start-stop system need?
A car with a start-stop system needs an AGM or EFB battery. According to the ANWB, all cars with a start-stop system are fitted with a battery like this. According to Varta, these batteries perform better than a standard battery. The manufacturer of your car decides which type belongs in it.
| Type | What it is | Where you find it |
|---|---|---|
| Standard battery | A lead-acid battery with liquid acid. | Cars without a start-stop system. |
| EFB (Enhanced Flooded Battery) | According to Varta, a more powerful version of the standard starter battery, with a polyester scrim around the plates and improved active material. | According to Varta, often in cars with a basic start-stop system, usually without brake energy recovery. |
| AGM (Absorbent Glass Mat) | According to Varta, a battery in which a glass fibre mat absorbs the acid, so it cannot leak. | According to Varta, in cars with an advanced start-stop system and brake energy recovery. |

When replacing the battery, you normally choose the same type. According to Varta, a start-stop battery may only be replaced with a battery of the same type. Bosch states in its technical information: replace an AGM with an AGM and an EFB with an EFB. According to Varta, switching from EFB to AGM can be a sensible upgrade. Volvo, for example, specifies for the V40 with start-stop that the battery must be of the EFB type or better.
When does a new battery need to be registered with the car?
On many modern cars with a start-stop system, the new battery has to be registered in the car’s system if the manufacturer requires it. Registering the battery is part of replacing it. According to the ANWB, a new battery in a modern car must be registered in the energy management system. This requires specific diagnostic equipment. The energy management system controls how the battery is charged. According to Varta, it uses information such as the type and capacity of the battery to do this. Bosch explains that the replacement is reported with a diagnostic tester, after which the battery management system is reset.
What happens if this is not done properly? According to Varta, the system then cannot use the correct charging strategy. The start-stop function may stop working and the new battery is not used to its full potential. How the registration works differs from car to car. Bosch mentions, for example, cars in which the battery is programmed and cars that learn the new battery by themselves while driving.
In broad terms, replacing a battery works like this:
- The mechanic uses the registration number to look up which battery type and capacity the manufacturer specifies.
- He fits the new battery, secures it firmly and checks the connections.
- If the manufacturer requires it, he registers the new battery in the car’s system.
- Finally, he checks that the car starts properly and that the alternator charges the battery.
According to the ANWB, the learning process is complete when the start-stop system, the climate control, the rear window heating and the electric power steering work normally again.
Does a hybrid or electric car also have a 12-volt battery?
Yes. According to the ANWB, a hybrid, a plug-in hybrid and a fully electric car also have a 12-volt battery, in addition to the large battery pack that drives the car. If the voltage of the 12-volt battery in a hybrid is too low, the car will not show the READY signal, according to the ANWB. You then cannot drive off. The ANWB recommends driving a hybrid once a week for at least twenty minutes.
According to the ANWB, replacing the 12-volt battery can be the solution to starting problems with a hybrid or electric car. Our mechanics hold the GMTO certificate, the Dutch qualification for working on high-voltage systems in hybrid and electric cars. You can read more on our page about hybrid car service and repair.
How much does a car battery replacement cost?
According to the ANWB, a new battery generally costs € 100 to € 300, depending on the type of battery (checked on 5 November 2026). According to the ANWB, an AGM or EFB battery for a car with a start-stop system costs more than a standard battery. Fitting by a mechanic takes about twenty minutes, according to the ANWB. If the new battery needs to be registered, that takes extra time.
