What are the odds?

[Lynn]

Now that I have the El Camino ready to sell (have it listed locally on CL) decided to get after a couple other small projects before the deep dive back into the LT-1 resto.

I think I will also be selling the AMG SL55. I just don't drive it. I keep it on two battery tenders. Yeah, over engineered and has two batteries; one under the hood and one in the trunk. Replaced the trunk battery about 3 years ago. Went to start it to pull it down to my shop and the under hood battery was dead. The battery tender I had just taken off 30 seconds earlier was showing full charge. Crap. Have to buy a new battery. I was able to jump start it with my 41 year old Bimmer without issue.

Drive the AMG down to the shop, making certain to NOT turn it off. Before I can pull it in the shop, I see that I need to move the Denali forward a few feet. Battery is dead on the Denali! Thumbitch! Two in one day. I was able to get it out of park and push it forward enough to get the MB in.

I am walking back to the house, and here comes Sherri the other direction. I figured she was just coming down to the shop to check on me. She asks what is wrong with the Prius. You guessed it. Dead battery!!!! That one I should have been braced for. It is 13 years old.

Three cars with dead batteries. All three drove fine last week. Here is the REALLY odd part. I walk in the living room and our clock is 3 hours behind. Yep. Dead battery.

What cha gonna do? Have a very full weekend planned, but realize some of those plans have now been interrupted. Oh well. Such is life, right?

Sorry to hear about all the bad luck.
Don't forget to charge your cell phone before that battery runs out.

Geeeezzzz.... you have some solar flare in your area that made all the batteries go dead ?? 3 vehicles is maddening, but the clock was just an insult...

Boy, I hope you don't have a pacemaker 🙃

You might want to go ahead and check your smoke detector batteries as well.

Was just thinking that when I got up this morning.

Getting weirder.

2004 Yukon XL Denali. Everything was working as it should. Battery died. Installed new battery. Immediately, I got CEL and a message that stabiltrac was turned off. Scanned and got codes P0120 (TPS circuit a) and P2135 (TPS circuit b).

Cleared codes but they came back. Don't see how I could have disturbed wiring at throttle body, but checked anyway. All connections are clean as can be.

Anyone run into this before?

I lived that dual battery issue with my fathers M-B. The little one under the hood would die and disable the car. Damn expensive rear battery too (used a Chrysler battery at 1/2 the cost). Strange setup, overengineered on many levels, happy to see that car go away....

I only use my MB once a month now, it always shows low battery until I run it a few miles. Had a 2019 Bullitt Mustang for three years, unless that car was driven every few days the battery would drain, had to have a Chek on it all the time.
Now about my daughters Volvo XC70………..

Guess the tide is turning. Let it set for two days. Started it up. CEL went out. Cleared codes and drove it. All good now.
