Cadillac CTS Battery Replacement with Computer Relearning and Windows Recalibration - 2008 to 2013

This how-to video guides you through all the steps you need to change, install or replace your Cadillac CTS V6 3.0L or V6 3.6L or V8 car battery, including the CTS-V.
Battery Group Part Number: H6 (search for this code when shopping for a new battery). This is a standard code and is understood by all part stores. All Cadillac CTS (2008, 2009, 2010, 2011, 2012, 2013) use this battery, the H6.
Tools Required:
- 10MM wrench or socket
- 13MM wrench or socket
- any sandpaper
- di-electric grease (optional)
- gloves
Video covers:
- Details on how to recalibrate the electronic throttle control \computer to relearn its home position
- Details on how to recalibrate power windows (Step 1: Press and hold the power window switch until the window is fully open. Step 2: Pull the power switch up until the window is fully closed, and continue holding up for about three seconds after the window is completely closed). Repeat for all the other windows.
- Safety tips (order of connection and disconnection of battery terminals) and a few optional tips, including cleaning and then lubricating the battery terminals with di-electric grease.
- Proper venting of the battery.
A battery saver tool can be used. If it is used the power windows won't need to be calibrated, however the computer relearning will likely need to follow the steps shown in the video.
Car shown: 2011 Cadillac CTS4 with the V6 3.0L engine.
A battery under normal driving conditions will fail typically in years 4 to 6. The battery changed in this video lasted 8 years! The batteries I use are mainly from Costco (Kirkland brand) and have worked well for me.

Thanks so much

[@HandyVal]

No problem. Happy to help.

Hi Val! Can i do this exact procedure for a 2020 Cadillac CT5? What about the sunroof? Any recalibration on the sunroof needed?

[@HandyVal]

The procedure should be very similar. The battery is in the trunk, and it should be in the same location as the CTS. I don’t think it has the same clamp on the positive as I show in the video. The learning procedure (windows) should be the same. The sunroof does not need any recalibration. The battery should be an AGM battery, which means it doesn’t need venting. I don’t have all the answers on the CT5 but hopefully this provides a decent starting guide. I wish I could be of better help.

My 2011 cts is in limp mode its starting to piss me off, still my favorite car.

[@HandyVal]

Have you tried reading any codes from the car? And is the check engine light on?

[@adamspicer-qj7ff]

On the 2008-2013 CTS can you tell me where the -12V cable anchors to the car in the engine compartment?

[@HandyVal]

Do you mean, the anchors if you had to boost the car?

[@adamspicer-qj7ff]

@@HandyVal I apologize, I said engine compartment by mistake. I need to verify where the cable from the negative post of the cable in the TRUNK attaches to the car. I have a no crank no start in this car I bought. It's definitely a grounding issue. My cable is grounded to the trunk lid himge

[@HandyVal]

Ok. I understand your question. In the battery compartment in the trunk, just to the right of the battery, there are three holes, they are a little less than 1/2 inch in diameter. The negative cable is bolted to the third hole, closest to the rear. Let me know if I missed anything.

[@adamspicer-qj7ff]

@@HandyVal that's what I needed. THANK YOU SO MUCH. I just bought the car on April 1st. Then a dead battery and it was a no crank no start after charging the battery. it was a grounding issue. After charging, the trunk light went out when tightening the negative post bolt

[@adamspicer-qj7ff]

@@HandyVal the guy who owned the car before grounded the battery to the trunk lid himge.
