Pre-emptive battery change?

[Sparky1337]

The battery in my 2016 lasted almost exactly 5 years. I did leave it in the garage for months during the winters without a trickle charge. The battery I replaced it with was an interstate from Costco and I’ve had it on trickle when I don’t use it.

I’ve seen batteries last months, to a decade or more without issue. The original battery in my GTI was 6+ years old and had 150,000 miles on it when the car got totaled. So technically it outlived the car lol.

I’d say if you can verify a battery is made by East Penn, like Deka, those are the ones to get. But most only sell Johnson Controls batteries and they’re ok, but I wouldn’t pay big money for it.

I have a 2019 Bullitt with 30K miles. Battery seems fine, but being 5 years old wondering if I should purchase a new one. Thoughts?

There are a lot of reasonably priced battery testers that use a modern algorithm to determine CCA. I've found that most good batteries test well above the stated CCA on the battery. When it gets to about 80% of the rating, change the battery even though the tester might indicate that it's still "good". My battery is 4 years old and it tests at 580 CCA which is just below the 590 CCA rating so I imagine I'll be changing it early next year sometime. Long gone are the old school "carbon pile" load testers.

I've had terrible luck with the original Motorcraft battery. Have owned a used '16 GT, 19 GT, and now a '19 Bullitt all with the original battery. And every single one leaked acid like crazy around the negative battery post. This was my '19 Bullitt when I got it a few months ago with 36k on it. (But at least I got a decent chunk of change off the price because of the battery)

TLDR, I'd get rid of it immediately and replace with another brand, especially at 5 yrs old.

Wow, that's nasty! Mine is still pristine and I check it monthly just to make sure there's no leakage, but I do have the felt pads and treatment that absorbs any acid that may seep through the terminal area.

I just tested my 2020 (2oK miles), original battery (I think), starts fine, runs at about 14.5 V on the dash. I put a tester on it and it reads 12.39 (car off) which lites up BAD Battery light on this simple tool. Not a daily driver but drove it about 45 mins today before testing. What do you think?

and can someone please link the BMS reset procedure. Thanks...

and should I just replace with another 590CCA battery (not sure the battery type/model?). 96R?

96R is correct. Odyssey AGM is a good choice. And use a tender/maintainer if you can.

I proactively changed mine with Costco 96R at 3.5 years.

I'm in the same boat. I have a 2019 GT with 71k miles. I bought it used in '20 but even if the battery was new then, which is doubtful, it's now over 4 years old. In my other vehicles I typically get no more than 3 to 3.5 years per battery, so it feels like I ought to replace it.

mine is 4 years and 7 months old. It s out of the car waiting to pick up a new battery. Glad I saw this thread and checked.

Generally speaking if your battery is five years old, you should preemptively replace it. That is if you want to save yourself some butt pain lol

 

[Silver Dragon]

Replaced my original battery at 7 years old as a precaution!

Changed it today and re set the BCM. I noticed that the volt gauge on the car was a little lower than with the old battery. Was always at 14.5 ish, new battery shows lower 14 s. On my handheld battery tester the old battery sat at 14.2 Volts and tested as bad (but never gave an issue). New battery tested off the shelf at 14.45 and tested as good (11/24 date) . NAPA Legend ,$200 OTD.
So this was a preemptive change after seeing the post, but it probably did need changing.

My car is going on 3 years old (21 model put in service April 22), I don't plan on changing my battery til at least 5 years or til it gives me problems. I do keep on a hard wired Noco 2A battery tender while parked in the garage more than 1 day, and I have a Noco GB70 booster in the trunk at all times just in case. I have never used the booster on my cars personally, but have boosted several friends at car shows and cruises when they have left their lights on, or listened to the radio a bit too long with the car off. It is a life saver, very much worth the money to have one.

My wife's 17 GT/CS convertible still has the original 2016 date coded FoMoCo battery in it with 8500 miles on it. No tender and garage kept.......Still cranks like new....KNOCK on wood!!!!

that s what I thought till I checked it. Caused the Volt gauge in car to run a little higher too keep up I think.

Gauge in the car runs @ 13.8 with everything on...... My voltmeter at the battery says the same at the battery. Like I said....knock on wood! My 22 MACh1 says just about the same......12,000 miles and shhhh.....I keep the key fob in the car 24/7.
