Start-stop on a Smart
Recent Smart models with start-stop need an EFB or AGM battery. We match the technology your car was built with, because a conventional battery will not last in a start-stop system.

German cars treat the battery as part of the electronics, and Smart is no exception. Most models use European DIN-size AGM batteries, monitored by a sensor, and a new one usually has to be registered to the car. We bring the diagnostic tool with the battery, so both jobs happen where the car is parked.

Most recent Smart models use DIN-size AGM or EFB batteries because of start-stop and energy recovery.
A new battery typically has to be registered, and coded if its capacity or type differs from the original.
Batteries mounted in the boot or under a seat have a vent tube that must be refitted.

FAQ
Short, direct answers. Message us if yours is not here.
On most Smart models from the last fifteen years or so, yes. Registration tells the energy management that a new battery is fitted, so charging is adjusted correctly. We do it on site with a diagnostic tool and confirm on your model whether coding is also needed.
It varies by model. Many Smart cars have it under the bonnet, while others carry it in the boot or under a seat to balance weight. Tell us the model and year and we confirm the location, the size and the access needed before arriving.
No, we advise against it. A Smart built with AGM charges at levels suited to AGM and relies on it for start-stop. A standard battery ages quickly under that treatment, and warnings usually follow. We fit AGM of the same size and capacity.
