When Is It Needed?

Most car batteries last 3–5 years. Frequent short journeys, extreme cold weather, and leaving electronics on while parked shorten battery life. If your battery is over 4 years old and the car is slow to start on cold mornings, it's likely time for a replacement.

Labour Time

A straightforward battery replacement takes 15–30 minutes. However, some vehicles (particularly BMWs, Mercedes, and cars with batteries in the boot or under the seats) can take longer due to access issues. Battery coding/registration adds 10–15 minutes.

Warning Signs

  • Slow or laboured engine cranking when starting, especially in cold weather
  • Dashboard battery warning light illuminated
  • Headlights dimming at idle or when using electrical accessories
  • Electrical systems behaving erratically (clock resetting, radio presets lost)
  • Visible corrosion on battery terminals or a swollen battery case

What's Involved in the Repair?

  1. 1

    The old battery is disconnected — negative terminal first, then positive

  2. 2

    The battery clamp or hold-down bracket is removed

  3. 3

    The old battery is lifted out (can weigh 10–20kg)

  4. 4

    The new battery is fitted, secured, and terminals reconnected — positive first, then negative

  5. 5

    On some modern vehicles, the new battery must be 'registered' with the car's computer using diagnostic software

Expert Tip

When buying a replacement battery, ensure you get the correct size, terminal layout, and CCA (Cold Cranking Amps) rating for your vehicle. An undersised battery may not reliably start your car.

Frequently Asked Questions

How long does a car battery last?

Most car batteries last 3–5 years. Short journeys, cold weather, and leaving electronics on while parked drain batteries faster. If your car struggles to start on cold mornings, it's likely time for a replacement.

Can I replace my car battery myself?

For many cars, yes — it's a straightforward job. However, some modern vehicles (especially BMWs and Mercedes) require the new battery to be 'registered' with the car's computer using diagnostic equipment, which requires a garage visit.
