Where is the battery located in the Cadillac CT6?
2 Answers
Cadillac CT6's battery is located in the trunk. The original battery is maintenance-free, so do not remove the cover or add liquid. When a new battery is needed, refer to the replacement number indicated on the original battery label. The Cadillac CT6 uses an Absorbent Glass Mat (AGM) 12-volt battery. Installing a standard 12-volt battery will shorten the battery's lifespan. The Cadillac CT6 is a high-end luxury sedan under the Cadillac brand, with body dimensions of 5184mm in length, 1879mm in width, and 1472mm in height, and a wheelbase of 3109mm.
When driving my Cadillac CT6, I often need to check the battery, which is actually hidden in the trunk, specifically under the cover panel in the right corner. The first time I looked for it, I thought it was in the engine compartment, but when I opened the hood, there was nothing there. Later, I lifted the soft mat in the luggage compartment and saw a metal cover—opening it revealed the battery box. This design is for vehicle weight distribution to ensure more stable acceleration, but it also means you have to bend slightly when replacing the battery, so be careful not to damage the trunk interior. If you're doing it yourself, remember to disconnect the negative terminal first to prevent short circuits, as both terminals are clearly marked. For long-term use, I regularly clean off dust to prevent rust, as the exposed battery tends to accumulate dirt. In short, don’t spend a fortune at the dealership—just keep a small wrench handy. The location may seem hidden, but it’s actually easy to find.
