Curious what others experience is with battery life on LC and LX cars. I am wondering if the battery location in trunk away from the heat of the engine helps - heat is bad for battery life. I have the original battery in both my 2010 Charger and 2010 Challenger and no signs of any weakness (knock on wood). The Charger was a "B-car" - originally delivered in May 2010 - timing belt failed before delivery - new engine - car had only 250 km on it when I bought it in November 2010. So it sat a significant time - which is hard on a battery (sulfation). But I put the car on a battery maintainer whenever it sits for more than a day or so. The Challenger being summer only is on a maintainer more than not. So I am sure that helps. I have only once before had a battery for 10 years and that was a Delco battery back in the '90s. Quality of the battery may be another factor - though I have seen Mopar original batteries replaced in as little as 3 years.

True that.

The effects of the average temperature where your car is located is more of a predictor. Batteries in Arizona don’t last very long. Highs during the summer months can be 120°F.
Batteries for me and my PT, being in North Texas, last about 2 years, and I buy good, premium batteries, no junk.

The one I just bought recently is from NAPA and it has a 5-year warranty and it's the largest (physically & specs) that I could get over a stock battery.

A contributing factor with PT's is such a small engine compartment. No doubt in my mind that such a small compartment contributes in part to short battery life. Texas heat can be a killer - I was stationed at Fort Sam in '82 for 6 months.

I don't have a LX or LC, but I do have a '06 Dodge Ram 1500. The original MoPar battery was 7 years old when I replaced it. I may have been able to get a few more years out of it, but with winter approaching and it being 7 years old, I didn't want to chance it.

I can't recall what batteries LX/LC use, but the latest and greatest relevant Fleet advisory for LD Pursuit models is to have their batteries tested at 4 years, and replaced at 5 (if the car is still under the 5/100 Fleet warranty).

I doubt that info is of much use for retail models, however, since those newer squads use a unique size/group and CCA AGM battery.

That said, if the battery in question is a wet-cell battery, a $5 tester saves a lot of trouble. That can also help track down a weak or dead cell. I would think a decent parts store battery should last a good 2 or 3 years, depending on how the car is used, the condition of the electrical system, and what modifications have been made.

My 2011 Chrysler 200 has the battery in the left fenderwell, and I replaced the original in July 2019. As a precaution, I replaced the original battery in my wife's 2012 200, which we bought new, in Aug 2019.
We live in MA, where OEM batteries tend to last 3-5 years. I replaced them with Interstate batteries, first time I've ever used them, because they seem to have a good reputation. Have also had good luck in general with Duralast from Autozone.

I always had good luck with the batteries, except in my 2007 Magnum. It killed them. There was a random parasitic drain and I didn't drive the car every day and eventually the battery would no longer hold a charge. If the doors were locked the drain didn't happen as often. After the third battery, I replaced the PCM for another issue and the random drain went away.

My brother bought my 92 Dakota new and had it 12 years. He went through about 5 batteries. Dealer could never find a drain (hint: they could not have really tried). He was in the service and away a lot, but it would not crank after sitting for just 3 weeks.
When I bought it from him, I found the same, and I measured a parasitic draw of nearly 100mA. I tracked it to the tach drive board, which, it turns out, uses both battery and ignition power for no apparent reason, by design. I removed the card, cut and jumped the battery trace to the ignition trace, and it worked exactly the same, and draws no current now when off.

FYI - Many newer vehicles have a IOD fuse (Ignition Off Draw). My '06 Ram 1500 has it. Owners manual recommends disengaging the IOD fuse if the vehicle will not be driven/used for more than 21 days.

I keep waiting for the battery in my 2012 Pursuit to die, but it keeps on going.

I'm pretty sure the battery in my Compass is all original.
Still starts every day, which is surprising since I know I drained it empty a year or so ago lol

On average about 3 years for most batteries here in the great white north.. did have a battery last 5 years in my HD Ram 2500 and the new one should technically last longer being an AGM.

My original battery on the Challenger went 9 years. Granted, it sat parked in enclosed storage and out of massive daily temp swings for about a year in 2010-11, and about 18 months of 2017 and 2018. Trunk location does make a difference.

it seems for newer cars the battery just dies, I mean no warning at all. One day all is normal the next day the battery is dead.
Mine was 8 years old, the original, and it gave me warning by cranking slowly for several days. But the alternator failed at the same time, so I ended up using AAA to bring the car home on the commute home from work. Even then, I ran on battery for 20 miles, until the transmission started shifting up and down on its own for a few miles. So I can't complain, it gave me lots of warning.
And the new alternator was revision G, so improvements had been made since the car was built.

The '93 Aerostar I had had the battery die without warning way back when. Drove to a Fas Mart to get coffee. Came out it was as dead as a doornail. No lights, no cranking. Nothing. It was a Die Hard that died in the month the warranty died (60 months).

Only two brands have died without warning on me - Die Hard, multiple times. Once it was an internal post connection that failed. It was always less than 3 years. The other was Exide Edge, which shorted internally after a few years while I was driving home. I found out when yellow-black smoke started coming from under the hood, and I could smell sulphur. I made it home without it exploding, and I shut it off, put my fire gear on, came back and disconnected it as fast as I could.
