Ford Puma Battery: Specs, Fitment & Common Faults

A stop-start system that keeps disabling itself usually isn't a dying battery — here's the reset procedure Puma owners report actually works.

Accuracy note: the Puma is built on the seventh-generation Fiesta platform, and shares broadly similar electrical architecture — a confirmed Fiesta fitment is Ford part H1BT-10655-FA (Varta EFB, 60Ah/600A, case size H6), which is a reasonable starting reference, but always confirm the exact type printed on your existing battery's label or check against your VIN before ordering, since Puma-specific trim and equipment can vary the exact spec.

Standard petrol/diesel, non-hybrid	EFB, 45-60Ah depending on engine and equipment level, case sizes vary (207mm, 242mm, 278mm length reported across the range)
1.0 EcoBoost mHEV (mild hybrid)	Genuinely uses TWO separate batteries — the standard 12V EFB starter battery for conventional electrics, plus a completely separate small 48V lithium-ion mild-hybrid battery pack (0.48kWh) that powers the belt-driven integrated starter/generator; these are different components with different failure modes, not one battery doing both jobs
ST (performance trim)	Higher-capacity battery (75Ah/700A EFB confirmed in parts listings) to support the additional electrical load of this trim

Stop-Start Disabling Itself Usually Isn't a Battery Failure — Here's the Fix Puma Owners Report

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 — worth trying before assuming your battery needs replacing.
