Land Rover Discovery Sport Battery Selection
The Discovery Sport replaced the Freelander with a compact family SUV offered in five- and seven-seat configurations. Early eD4 and TD4 power gave way to Ingenium engines, mild hybrids and a plug-in-hybrid derivative.
Use the finder above with the production year, engine, transmission and drive type. A full-size Discovery is a different platform and must not be used as the fitment reference.
Early eD4 and TD4 Applications
Initial Discovery Sports include two-wheel-drive eD4 and all-wheel-drive TD4 diesel versions. Their glow plugs and compression starting require the appropriate CCA, but battery specification can also change with gearbox and Start Stop equipment.
A front-wheel-drive manual should be identified separately from an automatic AWD car. Do not select from engine capacity alone.
Ingenium Petrol and Diesel Models
Later Ingenium powertrains introduced revised emissions controls, charging strategies and more connected electronics. Heated screens, cameras, infotainment and electronic parking functions all rely on stable voltage during wake-up.
A weak battery may create multiple driver-assistance warnings before cranking becomes obviously slow. Test voltage under load instead of relying only on the resting figure.
Discovery Sport Mild-Hybrid Systems
MHEV versions use a 48-volt battery and belt-integrated motor-generator alongside the ordinary low-voltage electrical network. These systems have different components, ratings and safety requirements.
A Lucas battery result applies only to the specified conventional position. Diagnostic testing should identify whether the low-voltage or 48-volt side is responsible.
PHEV Auxiliary Versus Traction Battery
The plug-in Discovery Sport combines a petrol engine with a rechargeable traction battery for electric driving. Low voltage remains necessary for locks, lights, modules and bringing the high-voltage system into ready mode.
A fully charged propulsion pack can coexist with an exhausted low-voltage supply. High-voltage battery service is not covered by a normal starter-battery listing.
Five-Plus-Two Seating and Tailgate Loads
Raising the third row, loading child seats or leaving the powered tailgate open keeps cabin modules and lamps awake. USB devices and climate control add further demand before the engine starts.
Family short-trip use can leave less charging time than expected. Occasional longer journeys or appropriate maintenance charging can help when the vehicle is used infrequently.
Terrain Response, AWD and Trailer Electrics
Terrain Response and AWD controllers require clean supply voltage to initialise correctly. Trailer sockets and caravan charging feeds need proper isolation so they cannot draw current after parking.
If warnings or discharge follow towing, inspect the trailer circuit rather than replacing the vehicle battery repeatedly.
Start Stop Battery and Support Arrangements
Applicable combustion models require the specified AGM or EFB technology for Start Stop cycling. Some years may also use an auxiliary support unit, making position identification important.
Register or reset a replacement where required. A main battery change will not cure a failed secondary unit or an unresolved parasitic drain.
Final Discovery Sport Checks
Confirm case size, polarity, terminal layout, base clamp, venting, Ah, CCA and battery chemistry. Include seating configuration, AWD and hybrid type when checking the derivative.
