Batteries have manufacture dates on them, so you should be able to tell if it was an original.

 

3 years

 

2014 Limited, original owner, battery lasted 6 1/2 years.

 

Battery life depends a lot on where you live & how the car is used (does it sit for long periods, daily driver, lots of short trips etc.).
I've found here in FL they last 4 - 6 years. I replaced mine @ 5 yrs just to be sure I didn't get 'surprised' as they seem to die without warning.

 

2014 Citadel v8 + the OEM battery lasted 7 years.

 

It's been my experience that battery failure mode has evolved over the years. It used to be, that you would experience weak starting with a slow, continual downturn in performance. While this can still happen, the last 3 batteries I have replaced, would start the vehicle and run it fine, then be DOA the next start. Or, in the case of a dying cell, start/run the vehicle as long as you don't let it sit too long between starts.

As far as oem batteries go, anywhere from 5-7 years is what I have observed. Vehicles in commercial service, ie. police/taxi are lucky to make it 3 years. The aftermarket replacements were the same.

Yes, seems to be the norm, good one day then bad the next with no warning.
I replaced my 2012 GC battery in 2020, PM.
My 2019 GC was traded in 10/23 with original battery AND original brakes (110K miles).

 

^^^ Exactly why I replaced mine @ 5 years even tho it seemed to be starting & charging just fine !

Battery on my Hellcat croaked @ 3 years with no warning, ironically @ the dealership .
Started her up just fine & drove there for a oil change & tire rotation & she would not restart in their service lane, so in went the new battery !

 

I truly must have had a battery from the gods... My 2013 I traded in this year had the original battery, no issues. I was certainly gambling....

 

My 2014 Limited V6 AWD was built in Sept 2013. I replaced the factory H7 battery with a larger H8 battery in Sept 2020. I did it as a precaution. I was not sure it was going to last though that winter and I figured after 7 years it was on borrowed time. As a point of reference, I live in NE Ohio.

 

Preventative maintenance, replaced at 5 1/2 years. 2014 R/T purchased new.

 

In dry as a bone Las Vegas I usually get 2-2 1/2 years out of any car battery. Just bought a used ram 1500 five months ago. Had an older battery in it. Had to replace it a week ago.

 

Bought new in October of 2018, still have both original batteries.

 

rhobil:
I would not say that too loudly. We have seen quite a few '18's here with one or both batteries belly up.

My 2014 original battery was till in the R/T when I sold it last year with 135K miles
. That is why I bought a new durango I didn't want to deal with changing the battery

 

The factory switched from the H7 size to the slightly smaller H6 size to make room for the start-stop battery. So I am sure that they will not last as long as some of the H7 have been noted in the 2011-15 models. I went the other with my 2014 V6 and installed the larger H8 size that came with the 3.0L Eco diesel in the JGC and possible the SSV, I just needed to switch the hold down bracket.

 

I always replace the battery with the largest cold cranking amp battery I can get. For instance, if the original battery is rated at 650 and there is a replacement that's 750 that's what I'd buy.

 

My 2014 R/T was purchased brand new in July of that year and still have the original battery.

It is garaged kept and only drive it about 4-6 time a year for long trips, of 200 miles round trip or more, usually 1000-1500 mile trips.

I know I am pushing my luck, but always drive with a jumper box and live close enough to auto parts stores to get a new battery if needed.

 

I thought I was in great shape, my '17 GT will be having her 6 year birthday next month and the battery still seems to be working just fine. You guys are scaring me!!

 

My 2014 Limited still has the original battery but, the remote start just stopped working. Planning on purchasing a new one stat.

 

My 2014 Limited (purchased new in March 2015) still has the original battery. No signs (as far as I can tell) of the battery going bad; in fact the display is consistently showing 15V (when operating the car). I have Nico Boost in a trunk just in case. Just wondering out lout how long I still have on that battery.

 

I would replace a battery from 2015 for sure. I had to do my original one from '16 just 2 months ago as it started to crank slow. Luckily we got no extraneous error messages as many do from a weak battery.

 

2014 Citadel V8 - Just replaced the battery with an H8. Original lasted 8.5yrs with no signs of impending failure.

 

Did your new bracket fit, Phil? I just got mine and it looks like the correct one.

 

I haven't put it in yet, but it does appear to be the correct one!

 

I replaced mine after 6.5 years after a "marginal" battery test rating, but I didn't notice any slow starting issues even on a cold Minnesota day. I probably could have waited longer, but didn't want to chance it. I bought the H8 bracket and upgraded the battery, it fit perfectly.

 

My recollection is that batteries from the non computerized cars way back tended to show some sign of failing in the form of a slow start, going dead etc. The last 4-5 batteries that have failed here were more like great one moment, and totally dead for the next start. If the weather is warm, and you don't mind the thought of not being able to go, by all means run 'er until she drops.

Here in our SW Ohio winters, being stranded with battery issues in very cold weather, may be penny wise, but also pound foolish IMO. Murphy's Law says it will likely crap out at the most inopportune moment.
After a full charge, or as much as it can anyway, a proper load test tells the story.

The 2006 Everstart Maxx battery in my Grasshopper 721D lasted 16 years!!!!!!
