Start-stop on a Genesis
Recent Genesis 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.
Start-Stop Battery ReplacementGenesis batteries · Yas Island, Abu Dhabi
Although Genesis is Korean, its batteries follow the European pattern: DIN-size AGM units, usually mounted in the boot to balance the weight of a rear-wheel-drive car. The G70, G80, G90 and the GV SUVs mostly have start-stop, and a sensor on the negative terminal reports battery condition to the car. The electric GV60 keeps a small 12V battery too.

On most G80 and G90 saloons the battery sits in the boot, with jump-start terminals in the engine bay.
Factory batteries on start-stop Genesis models are AGM and should be replaced with AGM.
The battery sensor recalibrates after the car rests locked for a few hours, so start-stop may return a day later.
Electrified models charge the 12V battery from the high-voltage pack, but it can still go flat if the car sits unused.

It is in the boot on most G80 models, behind or under the floor trim. If the battery is completely flat and the boot will not open electrically, we power the car from the terminals under the bonnet first and then get to the battery.
No coding is normally needed. The car's battery sensor learns the new battery by itself after the car has been locked and left for a few hours. Until then start-stop may stay off, which is normal and clears without a workshop visit.
Yes, the GV80 is fitted with an AGM battery from the factory, located in the rear of the vehicle on most versions. It needs AGM again because of start-stop and the heavy electrical load. We match the DIN size and capacity to the original label.
