Find the right replacement battery for your Smart

Smart vehicles include compact petrol models, stop-start cars and fully electric vehicles, so the correct 12V battery depends on the exact model, year and electrical specification. The replacement must match the required technology, capacity, dimensions, terminal position and hold-down.

Our Smart battery finder uses vehicle application data to narrow down suitable Lucas batteries for popular models including the Fortwo, Forfour, Roadster, City-Coupé, Cabrio and Smart EQ range.

Standard Smart batteries

Some earlier Smart petrol models use a conventional 12V starter battery. Compare the dimensions, terminal layout, hold-down and starting performance with the battery currently fitted.

Smart EFB batteries

EFB batteries may be fitted to certain stop-start applications. If EFB is specified, replace it with the same technology or a manufacturer-approved upgrade.

Smart AGM batteries

Some Smart models require AGM technology for repeated restarts, intelligent charging and higher electrical demand. Where AGM is fitted, do not downgrade.

Smart EQ and electric vehicle 12V batteries

Electric Smart models use a high-voltage traction battery to power the vehicle, but they also rely on a separate 12V battery for locking, lighting, control units and electronics. This finder identifies the 12V battery, not the high-voltage traction battery.

A weak 12V battery can cause warning messages, access problems or prevent the vehicle from becoming ready, even when the main traction battery is charged.

Smart stop-start battery replacement

If your Smart automatically switches the engine off when stationary and restarts it when you move away, it will normally require an EFB or AGM battery. Replace the fitted technology like-for-like unless Smart specifies an approved alternative.

Smart battery FAQs

How do I find the correct battery for my Smart?

Use the Smart battery finder and select your model, year, engine and fuel type. Then compare the recommended dimensions, terminal layout and hold-down with the battery currently fitted.

Does a Smart stop-start model need a special battery?

Usually yes. Smart stop-start vehicles commonly require EFB or AGM technology. Replace the battery like-for-like unless the manufacturer specifies an approved alternative.

Is the battery shown for a Smart EQ the main EV battery?

No. The finder is for the separate 12V battery, not the high-voltage traction battery that powers the car.

Can I replace a Smart AGM battery with a standard battery?

Normally no. If AGM is specified, fit an AGM replacement. A conventional battery may not cope with the charging strategy, stop-start operation or electrical demands of the vehicle.
