Match the Battery to Your Hyundai Tucson
The Hyundai Tucson name covers early petrol and diesel SUVs, the model that returned after the ix35, and recent mild-hybrid, self-charging hybrid and plug-in hybrid versions. Their low-voltage systems are not interchangeable.
Select the year, complete engine and fuel type above. A Premium, Ultimate or N Line badge describes equipment but cannot identify the required battery on its own.
Earlier Petrol and CRDi Tucson Models
Conventional generations include naturally aspirated and T-GDi petrol engines alongside several CRDi diesels. Two-wheel-drive and four-wheel-drive variants can use different engine outputs or electrical equipment.
Diesels require adequate CCA for glow plugs and winter cranking. Always match the exact capacity and production period rather than using a general SUV battery.
48V Mild-Hybrid Tucson
A mild-hybrid Tucson has a 48-volt battery and motor-generator as well as a low-voltage electrical network. The systems work together but their batteries have different roles and service procedures.
The Lucas unit shown for a confirmed conventional application does not replace the 48-volt hybrid battery.
Tucson Hybrid and Plug-In Hybrid
The Tucson Hybrid recharges its traction battery while driving, while the Plug-in Hybrid can also accept external charging. Both use high-voltage components for propulsion and a low-voltage supply for vehicle electronics.
Low-voltage arrangements vary by year and hybrid type. Some hybrid designs can use an integrated lithium-ion low-voltage section rather than a normal replaceable under-bonnet battery, so order only when the exact application is explicitly listed.
Battery Reset Functions on Hybrid Models
Certain Hyundai hybrids provide a 12V Battery Reset function that reconnects a protected low-voltage supply. This is not evidence that a conventional battery should be fitted, nor does it repair a battery with an underlying fault.
Follow the owner's manual for the exact Tucson before jump starting, charging or replacing any battery.
Family SUV and Towing Loads
Powered tailgates, heated seats, digital displays, trailer modules and camping accessories can create substantial demand. Avoid operating high-current equipment from the starter or auxiliary battery for long periods with the powertrain off.
A caravan or trailer electrical fault can also discharge the vehicle while connected. Test both sides of the installation if problems occur after towing.
Start Stop Technology
Conventional Tucson applications with Start Stop can require EFB or AGM batteries. Match the original construction, Ah, CCA and physical dimensions.
Disabling the feature does not change the vehicle's smart charging strategy, and AGM must never be downgraded to a standard flooded unit.
Low-Voltage Warning Signs
Petrol or diesel models may crank slowly, while hybrid versions can fail to enter ready mode. Keyless entry, powered tailgates, infotainment and driver-assistance systems can also behave unpredictably when voltage is low.
Test alternator or DC-to-DC output, battery condition and parked current before replacing unrelated modules.
Confirm the Tucson System
Compare case, clamp and terminals only after confirming that the selected version uses a replaceable low-voltage battery. See our Hyundai battery range or the related Hyundai ix35 battery and Hyundai Santa Fe battery guides.
If the Tucson is mild hybrid, HEV or PHEV, send the registration through live chat and our specialists will verify the exact low-voltage application before you order.
