How to change the battery in a Vauxhall Insignia?

I need to change the battery in my Vauxhall Insignia and I'm not sure how to do it. Can someone give me a step-by-step guide on how to change the battery?

First, make sure your engine is turned off and your parking brake is engaged. Then, locate the battery in your Vauxhall Insignia. It is usually on the right side of the engine bay.

Next, loosen the negative battery terminal with a wrench and remove it. Then, do the same for the positive terminal.

After that, carefully remove the old battery from its tray and clean the tray with a mixture of baking soda and water. Rinse and dry the tray before installing the new battery.

Finally, secure the new battery in place and reconnect the positive terminal first, then the negative terminal. Make sure everything is tightened properly before starting your car.
