[ARCHIVED THREAD] - AGM battery in my truck keeps dying

Posted: 2/16/2021 2:53:51 PM EDT

2016 F150 2.7L eco. I think it’s the cold weather more than anything. Battery is stock AGM. Haven’t been driving much lately. If I don’t drive it daily it will die after sitting for a day. Voltage is getting to 15.1v when charged. If I let it sit in the cold it seems to drop to 11.4 v or less and I can’t crank it.

Is it just a combo of the cold weather and the age/wear of the battery?

Seems to do fine in warmer weather.

The battery is on it’s last legs. See if you can get a partial exchange.
In any case, get a new battery. Doesn’t have to be anything fancy.
Fwiw, I’ve noticed that operating in hot weather kills them quicker.

Roughly 6 yr old battery? It’s dead. Time for a new battery. They don’t last forever. Plus looks like you live in a warmer climate. Heat kills batteries but their weaknesses typically show up in the cold weather since the battery is weak and has less cranking amps available already due to the cold and to add to that, the engine needs more cranking amps to start due to the cold.

Replace.

Short trips and cold weather play havoc on batteries. It's not enough time to recharge after a hard start.

3-4 years is about as long as you can rely on a car battery.

And by rely I don't mean someone doesn't have a 10 yo car battery that still works.

1. Modern batteries are made in Mexico bullshit

2. Modern vehicles use current flow sensors to minimize charging of the battery to reduce alternator losses which kills batteries faster

Yep, stick a fork in it.
It looks like it's a group 48, or the bigger one is a group 94.

I replaced the stock battery in my 2016 F-150 a month ago.
It just died one day.

My general rule of thumb is that for batteries,’when the warrenty expires I expect to need to replace the battery. Literally the moment my battery with an expired warrenty even gets slow cranking it gets replaced. Had them start the car slow one morning then dead as a hammer when I tried to start it at lunchtime. Not like the old days when you’d get a week of warning. Newer batteries give almost zero warning before they strand you. I carry a jump box all the time.

5 years old, time for a replacement.

Interesting, as it's all I've ever bought. I've always been told AGM is superior tech.

What is battery tier 1 these days?

We get 2 years out of batteries here. Consider yourself lucky. That reminds me, my truck is 2 years old....

Lithium Ion, but $$$.

Our AGM batteries are good, they set warning lights or disable ECO start/stop (auto shut off) long before they fail to start the car. You'd be surprised how many 10+ year old MB batteries I replace. Had one over 14 years last month.

If a non-deep cycle AGM battery gets depleted once, it is often done in my experience.

When my truck died, I checked the dates and found my truck left the factory with 3 year old batteries. Luckily it died in my driveway.

Amazon Santa delivered two AGM diesel truck batteries right beside my truck fender within 24 hours.

I've used them 1/2 dozen times over the last 20 years and they all have died in under 2 years.

A lot of people have better luck with AGM than I have.

I use conventional lead acid batts in all my vehicles, tractors, and motorcycles. 3-4 years is about the average life span. 4 bikes will likely need replacing this spring

I have to agree with others on here. Batteries are 3 to 5 year lifespans.

In saying that my newer battery charger with Battery Recond option has been able to revive my severely depleted AGM Motorcycle battery.

Odyssey batteries are not made in Mexico or China.

I’ve had fantastic luck with them. A bit more expensive, but to me worth it.

Lol. My US made AGM is going on 5 and a half years since I installed it and still starting my pickup in 0 degree weather.

AGMs are well known to handle cold and vibration much better than traditional LA. They generally last longer too. If you rarely run the vehicle (sports car, bike, ATV, boat) no fucking shit the battery isn't going to last long if you leave it hooked up. Disconnect it, at least. If you live somewhere cold, it doesn't hurt to pull the unused batteries in the winter and bring them inside, then rotate a trickle charger on them.

I know Optimas and the like are cool, but I don't need deep cycle capability on my pickup and I am perfectly happy with 5+ reliable years of service.

OP, my vote is to get the highest CCA AGM that will fit the stock mounting bracket.

Batteries being allowed to discharge too much kills them more than anything. Heat is a close second.

I have a riding mower with a typical cheap lawn mower battery on it. The battery is going on 5 years old. I charge it occasionally throughout the winter and it's still starting the mower. I was going to replace it last summer but decided to run it as long as possible to see when it would die.

I have a 8 year old yellow top Optima in my Kubota tractor and it's still working. Sounds like it's getting a little weak but it's still starting the tractor.

Make sure you put a correct group sized agm battery back in it. Preferably an oem battery.

The auto stop systems require an agm battery in most cases. And the charging and battery monitoring systems don’t like battery changes.

I know that on a newer Audi, the ECU needs to be reset with a programmer if you change the battery, or it will not charge correctly.

Maybe someone knows for sure about the Ford?

On a honda it needs to relearn the battery internal resistance. There is a process that involves turning the ignition on and off 20 times to do it. No scan tool procedure.

Even then if you do the relearn a d the battery is a different size it will cause issues.

Keep in mind that if a battery cycle life will be reduced if its capacity is discharged a significant % frequently, & especially if it drops below below threshold discharge depth. Charge maintenance is key to optimizing battery life.

I lived in AZ for 20 yrs, Always bought optimas and most lasted from 5-7 yrs.
Hell i took out a 5yr one out of in laws car and used it in my boat for 5 more
years until i sold it.

Aaaaaagggghhh. It's battery time for me here in AZ. Are you willing to say what brand of AGM gave you 14 years of service?
