Battery Finder
Modern vehicles require the exact technology, capacity and CCA specification to operate correctly, which means that choosing the correct battery is critical. Use our Battery Finder to identify the correct battery for your vehicle by registration, make and model, or VIN.

Why Correct Battery Specification Matters
Incorrect battery specification causes system faults, reduced lifespan and unreliable starting.
Modern vehicles rely on intelligent charging systems. Installing the wrong battery type, particularly downgrading from AGM to conventional, can result in premature battery degradation, charging imbalances, or even outright failure.
Matching physical size alone is not enough. Technology type, capacity (Ah) and Cold Cranking Amps (CCA) must all align with manufacturer specifications. For deeper technical guidance, read our Vehicle Battery Guide.
What the Battery Finder Checks
Our Battery Finder removes guesswork by helping you find the exact battery you need for your vehicle.
You can search in three ways. The fastest method is by registration number, which identifies the vehicle specification automatically.
If registration lookup is not available, you can search manually by selecting the vehicle make, model, year, engine size and power output.
VIN or chassis number lookup provides the most precise identification and is particularly useful where vehicles have mid-production specification changes.
Once identified, the system returns compatible batteries along with detailed vehicle information such as engine size, BHP, engine code, fuel type, drive configuration, production period and equipment level.
Battery Technologies Explained
Most vehicles fall into one of three battery categories: conventional flooded batteries for standard electrical systems, Enhanced Flooded Batteries (EFB) for basic Start-Stop applications, and Absorbent Glass Mat (AGM) batteries for advanced Start-Stop and high electrical demand systems.
| Feature | Flooded (Standard) | EFB (Enhanced Flooded) | AGM (Absorbent Glass Mat) |
|---|---|---|---|
| Suitable for Start-Stop | No | Basic systems | Advanced systems |
| Cycling Durability | Moderate | Higher than flooded | Very high |
| Charge Acceptance | Standard | Improved | Superior |
| Typical Vehicle Type | Conventional petrol/diesel | Entry-level Start-Stop | Advanced Start-Stop & high electrical demand |
| Cost Level | Lower | Mid-range | Higher |
-
Choose 'Flooded' if:
- Your vehicle does not have Start-Stop
- Electrical demand is moderate
-
Choose 'EFB' if:
- Your vehicle has basic Start-Stop
- The original battery was labelled EFB
-
Choose 'AGM' if:
- Your vehicle has advanced Start-Stop
- The original battery was AGM
- The vehicle uses regenerative braking
Key Battery Specifications Explained
| Specification | What it Measures | Why it Matters |
|---|---|---|
| Ampere-Hours (Ah) | Total energy capacity | Determines how long the battery can power systems |
| Cold Cranking Amps (CCA) | Starting power in cold conditions | Determines ability to start engine reliably |
| Voltage | Electrical system compatibility | Must match vehicle system (12V or 24V) |
| Terminal Layout | Physical connection design | Must match existing cables |

Frequently Asked Questions
Why can’t I just match the battery size?
Physical dimensions are only one part of the equation. A battery may fit the tray but still have incorrect CCA, capacity or technology. Modern vehicles require precise electrical specifications to function correctly.
What should I do if multiple batteries are shown?
Some vehicles allow more than one compatible battery depending on specification. In these cases, capacity (Ah), CCA and battery technology should match the original unit fitted to the vehicle.
Can I replace an AGM battery with a standard one?
No. Vehicles designed for AGM technology require its higher cycling durability and charge acceptance. Downgrading can result in Start-Stop malfunction and reduced battery life.
Why does my vehicle require battery coding after replacement?
Many modern vehicles use intelligent charging systems that adapt to battery age and condition. After installation, the system may need to be reset or coded so it recognises the new battery and applies the correct charging profile.
Should I still check the existing battery before fitting?
Yes. While the Battery Finder identifies compatible models, it is good practice to confirm terminal orientation and physical layout against the existing battery before installation.
Is higher CCA always better?
Not necessarily. CCA must meet manufacturer requirements, but excessive overspecification does not automatically improve performance and may not be supported by the charging system.
Do I need professional installation?
Many modern vehicles require battery registration or coding after replacement. Professional installation is strongly advised for AGM and Start-Stop applications.
