Memory Saver for Battery Change

[Turbine]

I have a 2020 GMC Acadia. I want to be ready when it is time to change the battery. Two questions:

1. Do I really need some sort of Memory Saver to change the battery so I don't mess up important computer functions?
2. If I need a Memory Saver, what is the best way to do this?

Thank you for your time and knowledge.

I just use my little battery tender. Negative to frame and positive to junction box or positive terminal if you have to.

1. It's a very good idea. Saves all the climate control, radio and convenience settings, learned throttle and transmission adaptions, emissions readiness monitors, etc.

2. I use this one. https://www.amazon.com/Schumacher-OBD-L-OBDII-Memory-Detector/dp/B00CH59OAS Plug one end into your OBD2 port and the other end into a jump box or power port of another car. Best thing is it tells you when both ends are powered up and it's safe to disconnect the battery.

Connect the leads together when the battery is out.

IMO it does a car good to have everything erased now and then.
