4:02 Agreed, I have a similar sized one as you have here, but also a smaller version with smaller tip...that's come in handy at times. I also have a similar apparatus with an adjustable mirror on the end. It's very useful for seeing around tight corners.
I had to replace my battery in my 2017 caddy XTS. And it was just like that. But I was able to cheat it out without taking all the wires loose. But it looks like you don't have as much room.. the reset was different. It had me lower one window and put it back up. Then another. Then another. Till done.
You dont use any grease or anything to protect your terminals from corrsion? I recently tried lithium grease but I dont like how it dried out somewhat.
