Hello everyone, I have a 2017 Prius (gen 4) that is starting to show some signs the 12V battery will need to be replaced soon. I am monitoring the charge via DC voltage with a multimeter in order to help prevent unwanted surprises. I am considering doing the replacement myself but in the interest of not damaging the computers, I am researching OBD2 memory savers that I can plug in to allow me to remove the 12V without risk. Does anyone have direct experience with using these memory savers, which one do you use (that I can still buy), and do you have any tips? I am mainly concerned with this tool as other threads cover mostly everything else in great detail but this important tool is hard to find details on. I saw a Scotty Kilmer episode with a simple OBD2 plug and positive and negative jumper leads that is obviously appealing for the price. But again, not going to plug anything in that I am not 100% sure about. Thanks in advance.
