Ford Galaxy Battery: Specs, Fitment & Common Faults

If the Galaxy's stop-start has stopped working, a documented charging reset is worth trying before assuming the battery has failed.

OEM Part Number: 670-750A

Genuinely important to know: Galaxy II (2006-2015) uses an Intelligent Battery Sensor (IBS) that monitors charge status — a genuine Ford replacement unit exists separately from the battery itself, and the system generally needs resetting or relearning after any battery swap.

2.0/2.2 TDCi diesel, standard fitment	276-278mm case, minimum 71Ah, 670-750A (EN)
1.8/2.0/2.2 TDCi, higher-power variants	315-317mm case, minimum 77Ah, up to 800A (EN)
1.6 EcoBoost petrol/1.6 TDCi, Start/Stop	EFB technology required — a standard lead-acid battery isn't sufficient for the frequent cycling involved

A Disabled Stop-Start System on the Galaxy Doesn't Necessarily Mean a Dead Battery

A genuinely common source of confusion across Ford's stop-start range: the system frequently disables itself and displays a warning about charging or cold conditions, and many owners assume this means the battery has failed and needs replacing. In most cases it hasn't — Ford's Battery Management System deliberately disables stop-start when it judges the battery isn't in a strong enough state to reliably restart the engine, which is the system protecting itself rather than malfunctioning. Owner reports consistently show this resolving itself after a full overnight charge on a proper smart charger, without any need to replace a perfectly healthy battery.

A genuine, documented fix worth knowing: many Ford 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. This isn't an official Ford procedure, but it's widely reported across owner forums as genuinely effective.
