New Batteries Question

[mikemann0]

My 17' still has factory batteries.

Not having any issues, but a thought occurred.

When removing both for a swap to new, does anything besides the radio lose memory or need reprogrammed MM3 to have memory?

Thanks.

If you remove one at a time and replace it, you shouldn't lose any memory.

Well, that's pretty simple, I suppose, LOL.

Long day brain not working fast enough (time change excuse maybe).

Thanks

I had wondered the same thing, so I was careful only to disconnect one battery at a time, thus maintaining the voltage.

Then I read that when replacing batteries, disconnect them to allow the Intelligent Battery Sensor to reset and adapt to the new batteries.

Now I do disconnect both batteries and have not needed to reprogram anything.

I don’t know if the radio loses memory as I don’t use the presets.

I do know my radio NAV information remains in my memory.

Well, shoot.

Have to dig deeper.

Thanks for that info, AK Bob.

Attached is where I read about the Intelligent Battery Sensor from Mopar Tech Authority.

When I replaced my starter, both batteries were disconnected (for obvious safety reasons) and reconnected.

The only thing lost was the clock setting.

Radio presets were fine, and the tune was maintained.
