Have a 2017 Sport with the original battery. Wondering if I should replace it as a precaution. Would like to get some feedback on when others have had to replace it. Thanks

3 years: Normal.
4-5 years: Good going.
\> 5 years: failure, just when you don't need it, likely.

Some members have reported problems with the computers that require a trip to a dealer to correct after running their battery too low. Waiting until you have starting problems to replace the battery is too late. It needs to be done proactively on our vehicles. I think 4 years is a good recommendation. You are on borrowed time in my opinion.

Appeciate the comments. Vehicle has only 20K miles on it and used in sunny FL. Found an Odyssey battery for $300 which I may order. Part of me says to wait until original dies, but don't want wife stuck someplace with a dead battery. Might mention this Renegade has been totally trouble free from day 0ne. Much more reliable than any other Jeep we have owned.

I was an early adapter of the Renegade. Up until I owned this Renegade and started reading reports of problems caused by dead batteries, I always ran my vehicle batteries until they would barely start the engine. I will not do that now.

I intend to replace the battery in my 2021 Trailhawk every three years. We've all seen on this Forum too many weird electrical issues starting to pop up at that point, many (though not all) due to a weak battery.

three years if parked outside year round, maybe four if you park inside

Both extremes of hot and cold temperatures are hard on engine components. That and the age would make me opt for a change as you are about at the time for it to give up the ghost. It will be fine until it isn't and then you're in a bind. That battery and that Renegade will not give you any notice. The yellow top Optima battery has decent reviews but I'd just go with a name brand and not a discount battery.

3 years for us than we went AGM!

During one of my oil changes at the dealer (when I bought mine, I got one of those packages, 3 oil changes, 3 tire rotations, 27 point inspection for 179 that I keep renewing), the report came back and had the battery as "fair". I left the dealership and went straight to NTB and had a new battery installed. Not worth the risk in getting "as much as you can" out of a simple battery.

My boss says I'm wasting money replacing a battery that isn't dead yet. I disagree. Sure, in the days of yore you could wait until the battery was flat then have your friends push start or jump start you for a few days, but in these heavily computerized vehicles, that's a no go. Batteries nowadays do a lot more than light your headlights and engage your starter solenoid....

Do it. The electrical system (especially the power steering) on the Renegade needs a solid battery.

Yeah, I have a 2017 latitude with original battery and it's still cold where I live. I noticed it was turning over a little slow the last start. Also, I started down the road out of my driveway and it would barely accelerate. Pushing down the gas peddle and it would just bog. No trouble light. So I creeped back to my driveway and shut it off. Waited a minutes and started it back up and everything was fine.
So I'm thinking I need a new battery too.

We just replaced ours it was 5 years old but testing showed it was still good and had 590 CCA so not much degradation. The Battery said 600 CCA on the top. I was impressed but with us going on vacations and stuff I felt it was time to replace it just for general purposes !!

I've changed many batteries in many vehicles thus far in life. But with all the talk of how sensitive the electronics are on the Renegades, I am little concerned.
Is there any special procedure or something to be careful with when changing the battery?
Thanks

Not as far as I can see. My 2020 USB Service Manual just says to disconnect the negative post of the battery when doing electrical work. After first unplugging the Intelligent Battery Sensor first, if you've got that (the red thing on top of my battery):

After that, the battery obviously isn't grounded any more; there's no electrical circuit; and removing the positive post is trivial.

Nothing special in there about connecting the battery back up.

With some vehicles (like our 2009 VW Mk5's), there's some simple adaptation that has to be done when the battery is disconnected, with the power windows and the power steering. But I don't see anything like that here...

Replaced it on my 2017 late 2022.

Well I planned to get a new battery this Saturday. Went out to start the car this afternoon and lights going off everywhere and not enough juice to turn over the starter. So I will definitely be replacing the battery this Saturday.

I’m in the same position, my 2017 a little lag when starting so I’m replacing it this week at Mavis. Putting in a 24 month Exide battery.

I put in a new battery and everything was fine. To my surprise, the radio still had all the stations I saved and all the car settings were still saved along with the blue tooth devices.
