Hybrid 12V auxiliary battery£180 to £450

What affects the cost

Battery type and size

Standard lead-acid batteries are the cheapest. Stop-start cars need pricier EFB or AGM batteries, which can more than double the part cost.

Make and model

Larger engines and premium German marques often need higher-capacity batteries, and some need the new battery coding to the car.

Fitting and coding

Most fits take under an hour, but awkward battery locations (under a seat or in the boot) and battery registration add labour time.

Where you buy

A garage that supplies and fits is usually the simplest option. Quotes vary a lot between garages for the same job, so it pays to compare.

Signs your battery needs replacing

  • The engine cranks slowly or struggles to start, especially when cold.
  • The battery or charging warning light shows on the dashboard.
  • Headlights dim at idle or when you use several electrics at once.
  • Stop-start stops working, which often points to a tired battery.
  • The battery is more than five years old and has never been replaced.

How to pay a fair price

The same battery job can vary by £100 or more between garages. The simplest way to avoid overpaying is to compare a few local quotes before you book. Describe your car and the problem once on RepairRadar, and trusted local garages send you competing prices so you can choose on cost and reviews.
