The original Ford battery

My 2021 Ford Kuga PHEV still had the original factory battery.

The main characteristics can be clearly read from the label:

  • 12 Volts
  • 45 Ah
  • 390 A (SAE/EN)

This data is useful for identifying the installed battery and checking the compatibility of a possible replacement or a future upgrade to a higher capacity AGM battery.

If you are considering a battery upgrade, we recommend you also read AGM vs. EFB Batteries: Differences, Advantages, and Which to Choose, so you can choose the technology that best suits your Ford Kuga PHEV.

The components in the battery compartment

When the battery compartment is open, you can see some components that are essential for the correct functioning of the Ford Kuga PHEV's electrical system.

Knowing them is useful both during a simple check and before a future battery replacement.

BMS (Battery Management System) sensor

The sensor BMS (Battery Management System) It is installed on the negative terminal of the battery and constantly monitors parameters such as voltage, current, and state of charge. This information is sent to the vehicle's control units, which efficiently manage the electrical system.

During any work on the battery it is important to avoid impacts or damage to this component.

To check the battery status and monitor the BMS parameters you can follow our guide on How to check your Ford Kuga PHEV battery with FORScan

To perform an electronic diagnosis on the Ford Kuga PHEV you need a FORScan compatible OBD2 scanner.
Vgate vLinker MC+ OBD2 Bluetooth Diagnostic Scanner for Car Electronic Diagnosis.

Vgate vLinker MC+ OBD2 Scanner

To perform a complete diagnosis of the Ford Kuga PHEV, you need a FORScan-compatible OBD2 scanner. The Vgate vLinker MC+ allows you to read battery parameters, monitor the BMS sensor, and access the vehicle's electronic modules easily and reliably.

Why it can be useful to you

  •  Compatible with FORScan
  •  Reading the Ford Kuga PHEV modules
  •  Checking battery and BMS parameters

Vent pipe

The battery uses a vent tube that vents any gases produced during operation.

When checking or replacing the battery it is important to make sure the hose is connected correctly.

Mistake to avoid

Always check that the vent pipe is inserted correctly and that any opposite hole is closed with the cap provided by the manufacturer.

Fixing bracket

The bracket holds the battery securely in place and prevents movement while driving.

If you install a battery with a different size in the future, always check the compatibility of the fastening system.

Main fuse

Next to the battery is the main electrical system fuse.

During a simple visual inspection it is not necessary to remove or manipulate it.

If you don't know where to connect the diagnostic scanner, please consult the dedicated guide. Ford Kuga PHEV OBD2 socket: where it is located and how to use it

Why is the battery in the trunk?

Ford chose this location for several reasons:

  • better weight distribution;
  • less exposure to engine heat;
  • optimisation of the space available in the engine compartment.

This solution is common on many hybrid and plug-in hybrid vehicles, where the engine compartment houses numerous components of the propulsion system.

What to check when the compartment is open

Take advantage of the access to the compartment to check:

  • terminal status;
  • presence of any oxidation;
  • correct battery attachment;
  • vent pipe connection;
  • integrity of the wiring.

If this is your first time using a diagnostic tool, you may also find it helpful to read OBD2 for cars: what it is, how it works, and how to read errors.

Check the battery properly

Before considering replacing the battery, it's worth checking whether it really needs replacing. A simple tester allows you to check the voltage and charge level in just a few minutes, avoiding unnecessary replacements.

Before replacing the battery, it is always advisable to check its condition with a dedicated tester.
