My 2016 453 was built in the fall of 2015 so battery is four years old. When I go to change the battery do I need to keep the electrical system energized so the tranny and computer retains all current settings? If so, how do I keep it energized? Thanks much! Mike700

I’m not an expert on this but I doubt the computers will lose memory but your radio presets may. There is a device that uses a 9v battery that connects to the terminals and will keep memory for the short time the battery is disconnected. If buy from a place that changes out the battery for you they will most likely use one of those devices.

So you are just going to change the battery for the heck of it? I usually shoot for ten years on my batteries. Agree with Oliver on the radio presets.

I can't speak for the 453, but on my 451, I am on my third battery and I have never lost any presets or other functions while I had it disconnected for a few minutes.

dealer change battery after 3 years,I complain about flickering on the lights ,they tested and changed in guaranty.
Try to use a 12v external battery like the use in alarms with clips when you change the battery.
(9 volts battery dont provide current.

I had to change the battery in my 2017 453 (just went flat) and the only things affected were the radio and the clocks. No relearning ala 451 on the other stuff. Battery is a type 47, Walmart and Sams both have them.

No you don't have to worry about that. I just got back from a deployment to a deader than dead battery in Minimus Prime (2016 453). Got a replacement from Auto Zone. The surgery to get it out is ALL cosmetic. Just start the vehicle like normal and reprogram the radio and voila!
