Replacing a car battery: price, symptoms and lifespan

A car battery lasts four to six years on average. After that, cold-morning starts become the first warning sign — a slow crank, a flickering dash, an unreliable ignition. This page explains how to recognise a weak battery, what a new one costs and how to source one directly from Dutch sellers without paying a marketplace cut.

What does the battery do?

The battery supplies current to the starter motor, powers the on-board electronics when the engine is off, and acts as the stable buffer for everything the alternator does while you drive. Charge balance depends on driving long enough for the alternator to refill what each start drains. Short urban trips, cold weather and an ageing alternator all break that balance.

Signs of a weak or failing battery

The engine cranks slowly, particularly in cold weather or after several days of inactivity.
Dashboard or interior lighting dims or flickers during start.
Power windows or seats run audibly slower.
The battery warning light stays lit during or after start.
The car fails to start after three or four short trips without a jump.
White or green crystalline buildup on the terminals (sulfation).
Resting voltage measured below 12.4 V.

When to replace

Under Dutch conditions a maintenance-free lead-acid battery lasts four to six years. Short trips, start-stop systems and cold winters shorten that. AGM and EFB batteries for modern start-stop cars tend to last longer but cost more up front. Rule of thumb: from year three onward, ask for a battery test at every service, and plan replacement once measured capacity drops below 70%.

What does a new battery cost?

Price depends on type (standard, EFB, AGM), capacity (Ah) and brand. A suitable battery for a small petrol car starts around € 75. An AGM battery for a larger diesel with start-stop runs to € 180 – € 240. Used or refurbished batteries are cheaper but typically carry a shorter warranty; always check the production date stamped on the top — a two-year-old "new" battery has already lost a sizeable fraction of its service life.

DIY or workshop?

Difficulty: Easy

On most older cars this is a fifteen-minute job: disconnect the negative terminal first, then the positive, release the hold-down clamp, swap the battery and reconnect in reverse order. Modern start-stop cars often need the new battery coded into the BMS (battery management system) — otherwise start-stop stays disabled and the alternator may overcharge.

Spanners (usually 10 or 13 mm) or a socket set
A clean cloth and terminal grease
Optionally: a memory-saver (OBD-port plug-in) to preserve radio + seat presets

Frequently asked questions

How long does a car battery last?

Four to six years on average under Dutch conditions. Short trips and cold winters shorten the lifespan; AGM batteries for start-stop systems tend to last a bit longer.

What does a new battery cost in the Netherlands?

From around € 75 for a small petrol car, up to € 240 for an AGM battery in a large diesel with start-stop. Used or refurbished is cheaper but carries a shorter warranty.

Can I replace an AGM battery with a standard lead-acid one?

No. The car expects an AGM charging profile that a standard battery cannot accept. The BMS detects this and disables start-stop; long-term it damages the alternator or the new battery.

How do I know which battery fits my car?

Capacity (Ah), cold-cranking amps (CCA) and type (standard / EFB / AGM) are printed on the top of the existing battery. Search by licence plate or OEM number on onderdelen.autos and only fitting batteries are shown.

What do I do with the old battery?

Hand it back to the seller or take it to a chemical-waste collection point. Lead-acid batteries are classed as Small Chemical Waste in the Netherlands; many sellers refund a deposit.
