Holding a charge

[Look29]

I have a 2007 Explorer advance Trac rec does anyone know how long the computer will hold the settings with Battey disconnected. If the battery is disconnected when will I have to think about retraining it?

Probably only a few minutes. You may be able to use small jumpers wires from a small 9v battery to the main power cables to keep power for a little longer. But if you do loose power the relearn processes is not that hard.

Ty for the reply. I was just going to clean off battery. But this will be good for many other procedures. I figure as long as the key isn't turned it should be good.
