thanks for the video. just a side note on order of operations :) be sure to always disconnect negative (-) terminal first - your entire car chassis is a negative terminal and if you start with positive and touch chassis with a tool - you can short it, potentially damaging electronics, producing sparks etc connecting terminals back is reverse: positve first, negative second

*** Remove the cabin air filter door to get hinge of the battery cover far enough to open; don't just break the hinge on the battery door. Good time to replace the cabin filter also.

and now, let the rattling noise begging because you did not put the battery cover properly in the hinges. What a butchering job. But, thanks for showing the wrong way of doing it. I learned more than if it had been perfect.

It keeps electronics working - stored codes etc-when the main is dead or disconnected

Ok friend did you disconnect the main battery first?
