Ford Kuga Battery: Specs, Fitment & Common Faults

Early Kuga PHEVs had a genuinely undersized 12V battery causing dead-battery lockouts — here's the fix Ford applied, and what to check either way.

OEM Part Number: EFB100

Accuracy note: Ford has fitted several genuine factory battery types across the Kuga range depending on engine and equipment — owner reports confirm Type 100 (EFB) as a common Stop-Start fitment, with Type 110 (EFB) used on some diesel variants with higher electrical demand. Always confirm the exact type printed on your existing battery's label, or check against your reg/VIN, before ordering.

Common Stop-Start fitment	Type 100, EFB technology (e.g. Varta EFB100)
Higher-demand diesel variants	Type 110, EFB technology (e.g. Varta EFB110), roughly 75Ah
Case size guidance	Genuine Ford-fit batteries are typically 175mm high — some aftermarket AGM options run to 190mm and may not fit without adapting the tray, worth checking dimensions before buying

Confirmed: The Kuga PHEV Specifically Had a Documented Battery Undersizing Issue — Ford Kuga Battery

If your Kuga is the plug-in hybrid (PHEV) variant, this is worth knowing directly: early examples were fitted with a standard EFB 12V battery that owners and Ford both found genuinely wasn't up to the demands the PHEV's electronics placed on it, leading to a well-documented pattern of dead 12V batteries and cars that wouldn't unlock or start despite the main high-voltage battery being fully charged. Ford's own response on some affected cars was to upgrade to an AGM battery, which handles the PHEV's higher standing electrical load considerably better. If you own a Kuga PHEV and have experienced repeated dead 12V battery issues, upgrading to AGM specifically (rather than replacing like-for-like with another EFB) is worth discussing with a specialist, even if your original battery was EFB from the factory.

A genuine, documented fix worth knowing (applies across the wider Kuga range too): many owners report a specific "charging reset procedure" resolving persistent stop-start and low-battery warnings without needing a new battery: with the ignition on (engine off), flash the main beam headlights five times, then press the brake pedal three times, and wait roughly 20 seconds for the battery warning light to flash, confirming the reset. Several owners specifically report the stop-start system disabling itself due to Ford's battery-age charging algorithm rather than genuine battery failure — worth trying this before assuming a new battery is needed.
