Start-stop on a Cadillac
Recent Cadillac 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.

Cadillac moved to AGM batteries early, and most models sold in the last several years have engine start-stop that depends on one. Sizes follow American BCI groups that match the European H6, H7 and H8 cases. The Escalade keeps its battery under the bonnet, but several saloons such as the ATS, CTS and CT6 carry it in the boot.

The Lyriq and Escalade IQ are electric, yet they still use a 12V battery to power the computers before the drive battery connects.
Recent Cadillacs monitor the battery with a sensor on the negative cable, and the system should be told when a new battery is fitted.
Boot-mounted batteries are vented to the outside through a small tube that must be reconnected to the new battery.

FAQ
Short, direct answers. Message us if yours is not here.
On recent Escalades with start-stop, yes, the factory battery is AGM and should be replaced with AGM. Older Escalades without start-stop can use a quality calcium battery in the right group size. We read the label on the fitted battery and match its technology and size.
It is in the boot, under the floor panel or behind the side trim depending on the model year. Jump-start terminals are provided under the bonnet for boosting. We replace it from the boot and reconnect the vent tube so gases are carried outside the cabin.
Yes, alongside the large drive battery the Lyriq has a 12V battery that runs the locks, screens and control units. If it goes flat the car will not power up even with a full drive battery. We test it on site and replace it when needed.
