I had mine tested at several places, but Advance did something I've never seen before, they hooked up a small battery to the OBD II port to keep power on the computer. Supposed to safeguard the computer
. I don't know what happens when you disconnect the battery to put in a new one
but just thought I would pass that on for whoever is interested.
I think the device they used that you're talking about maintains radio presets. There is a similar device you can but that works thru your cigarette lighter....although since you have (2) batteries that are connected in parallel....they really didn't need to do this, since they only replace one battery at a time.
