Your battery has lasted longer than the average 4 years. You're doing well. You might be on borrowed time. If you want to be safe go ahead and replace it. And by the way the 14.9 volts while driving is the alternator charging voltage - not the battery voltage so don't go by that. If you want to know your battery voltage measure it with a voltmeter when the vehicle is turned off. It should be above 12 volts minimum if properly charged and healthy. Another thought - if you're really getting 14.9 volts while running confirm that with an actual volt meter as well - that's a little high should be more like 14.3 volts. Your regulator may be not quite doing the job it should be. But don't panic. Best of luck and happy holidays!How long are your batteries lasting? I'm on year 5.5 with original battery, about 65k miles on the truck, voltage is at 14.9 while driving.
Should I replace it now before it leaves me stranded some day?
I had to replace both batteries this weekend in my 2019 ram 2500. Died with no warning.How long are your batteries lasting? I'm on year 5.5 with original battery, about 65k miles on the truck, voltage is at 14.9 while driving.

I also have a 2019 that's 6.5 years old. I just replaced it with an OEM even though I was not or ever had a problem. Charging voltage was 14.8 on the old battery, 14.9 on the new one.How long are your batteries lasting?

You aren't getting it. I carry a jump pack in every vehicle. Batteries go flat for many reasons, like leaving a door ajar. You can also flatten a battery winching where you can't idle the pickup. Also, I won't jump someone else using cables with the new vehicles so the jump pack serves that duty. Just one of the reasons to have a jump pack is if my battery dies.My 2018 Big Horn battery was replaced under warranty in February 2021, with 3 months left on the 3 year warranty. Symptoms were that it could no longer remote start but would start if I climbed in the vehicle and turned the key. Now here I am at almost the 4 year mark with the replacement battery and I'm kind of wondering if I should replace it?
I don't see the point of buying a battery jump starter for $60 to $70 then use it when the battery is dead and THEN buy a new battery for about $150. Why not just preemptively replace the battery?
First check your battery warranty to see when it expires. Then have it tested a couple weeks before it expires if it is getting weak then change it while still under warranty if not then it is a guessing game as to when you may need a new one could be right after it expires or two years later you never know.There is not much visual difference between many regular flooded batteries and many of the AGM's.
An interesting read on AGM's

I doubt you'll have any issues.I used to disconnect the batteries in both my truck and in both the wifes 16 and 19 Challengers all the time,and never once did i have any issues.The 1320 Challenger would have to sit for an hour with-out cycling the key to get the "Drag" pages back,but that was it,the 16 had everything come back as soon as the battery was reconnected,except the equalizer settings,i'd have to reset those. My 300 right now is sitting with the battery disconnected,and the only thing i'll have to reset will be the radio's equalizer settings,and it's analog clock.My 19 1500 classic is in the same boat as we speak. For the past month now, I've found that she may not start with the factory remote. And when I jump in, you can hear that the starter is having a challenge to turn her over. In fact, if I'm lucky, she will start on the first turn of the key, if not. I had to boost her. when this first occurred, I test the battery and the alternator with my toaster style Tester and she reported as good.
For the past month, I've had to place the battery on my trickle charger over night. No problem then with starting her. Even when the temps drop to -30c!! HOWEVER, I also keep my jump pack with me as on a couple of occasions I've need to jump her after running a short trip to say 1 store, then on to another. I do have a parasitic draw due to my dash cam that records 24/7 (front and rear).
I'm waiting till Boxing Day to run out to get a new 950cca wet battery that (hopefully) should be on sale!
I would like to hear/know more about any programing or adjusting that I may (or will have to do) with my AlphaOBD. ANY insights on that from the AlphaOBD/RAM experts here WOULD be appreciated!!!!
Later Challengers don't lose station presets or the clock,the only thing they lose is the equalizer settings.Are you sure your 09 loses the radio presets. I'm going to have to check with my buddy,as he has a 09 SRT Challenger with only 18,000 miles on it,and he disconnects the battery every winter,and i don't remember him ever saying it lost the radio presets,but then again,i've never specifically asked him that question.Interesting thread....
In addition to my 2022 RAM 1500, I have a 2009 Challenger RT that has an AGM battery, installed in the trunk. A few years back...2019/2020-ish....I replaced the battery. The car spends more time than not sitting safely in the garage, but does get its legs stretched every month or so. I keep it on a trickle charger - got some severe parasitic drain from after market Stereo/GPS, Alarm, etc. I hate a dead battery and having to reset clocks, stereo preferences, SXM presets, etc, etc, etc.
Anyhoo...about two months ago I went to start it up and got the 0000039 dsplayed in the odometer. Looking it up, it told me the battery was going bad. Went to OReilly's where I bought the battery. They put their tester on the engine compartment connectors. The tester said the battery was wek so they gave me a free replacement.
Still got the 0000039 after replacing it. The OReilly guy said "Drive it and see if it goes away." I did, it didn't. Went back about an hour later, they said something else must be up. I asked if the battery was still free, they said Yep.
More research and found something that said corrosion on the battery connectors could cause the 39. I disconnected the battery ground then wire brush cleaned the trunk and engine compartment leads and connectors. The 39 went away. All appears good now, except my alarm chirps every time I start it up. Gotta look into the reset procedure after pulling the battery.

I replaced the 19s battery in march.It was fine but I’ve always done 4 years the old battery sits in a battery box on a trickle charger so I can use it on trips where the freezer is in the back.Its fused and wired in to the main #2 copper winch wiring that goes to the bumper.It works,but honestly it’s still good.
