Car battery test & replacement in Woking

Slow starts or a flat battery? We test the battery and charging system, and fit a replacement if it needs one.

A slow start, flickering lights or a car that won't start on cold mornings often points to a tired battery, but not always. The fault can also be in the alternator or charging system. We test the battery and the charging system first, so you only replace what is actually faulty.

Most car batteries last roughly three to five years, depending on how the car is used. Short journeys, cold weather and heavy electrical loads all shorten their life. If a replacement is needed, we fit one that suits your car.

Signs your battery is failing

  • A slow or struggling engine start
  • A clicking noise but the engine won't turn over
  • The battery warning light is on
  • Dim headlights or flickering interior lights
  • The battery is more than four or five years old
  • The car needs jump starts

What we do

  • Test the battery condition
  • Test the charging system to check the alternator is doing its job
  • Check the terminals and connections
  • Fit a replacement battery when it is needed
  • Quote before any work starts

Battery questions

How long does a car battery last?+

Roughly three to five years is typical, but it varies with the type of journeys you make, the weather and how many electrical items the car runs.

Can a flat battery be recharged?+

Sometimes, but if it keeps going flat the battery or the charging system may be at fault. We test both to find out which.

Why does my car battery keep going flat?+

Common causes are an old battery, lots of short journeys, a faulty alternator, or something draining the battery when the car is off. A test will show which it is.
