More battery questions

My daughter has a 2018 F-150 XLT 302A. She bought the truck new, it has under 30K on the clock and she's been deployed for the last 8 months. The truck has been sitting next to her house covered with the battery disconnected.

I'm heading down to her house in about three weeks to get her truck and car ready for her return in about three weeks. Since the truck battery is the OE battery, I recommended to her that we just replace it based on my personal experience with OE Motorcraft batteries. I've never had one last more than 3 1/2 years from the date of vehicle purchase. In my mind, that puts her squarely in the crosshairs of battery failure.

Looking at batteries and I see that both AGM and flooded batteries are available for her truck. Should O choose one over the other. It seems that AGM batteries started making inroads closer to the 2019 / 20 model years. Does it really matter?

Unless you want to get super technical, you can't go wrong with either. I get AGM because, well just because. That's how much thought I give it.

Thanks for your service, sir.

I'd charge it, start it, take it to Ford, replace it, and have the blm system reset correctly. Ya, you can get a better battery, but you still need to correct the blm system.

The AGM is nice because (1) They will never require water, and (2) They can handle a bit lower discharge level. As long as it has enough CCA, it is probably the better choice.

Ive seen way too many AGM battery failures on Motorcraft. I would just drive the battery you have since its been disconnected all this time. I have seen motorcraft batteries last up to 9 years, and Ive seen then dead coming off the transport when new. Battery quality has gone downhill for almost all brands these days from my experience. Look for the best warranty for the money paid. All batteries are expensive now. Even Wally World Never Start are expensive. IMHO

My O'Reilly Super Start has been going strong for 4 years now. That's double the life that the OEM one gave me. I wouldn't mess with the old one. It seems that if they get below 10 volts or so, there's no coming back. It's easier to just buy a new one than to charge/jump her truck, drive it to the dealer, wait for them to change it and reset the BLM and wait all that time. From what i understand right now, many dealers won't have the correct battery in stock anyway, they will have to order it.

Hey Tim, glad to hear your daughter is headed home safely.

I just replaced the factory AGM in my truck with a East Penn battery branded as Duracell Ultra AGM from local batteries plus bulbs. I wanted to go with the Northstar X2 but they didn't have any in stock.

As mentioned the BMS will need to be reset - this can be done without the dealer or forscan using below procedure:

Procedure must be carried out within 10 seconds:
1. Switch ignition on (don't start)
2. Pull and release high beam 5 times
3. Press and release brake pedal 3 times
4. If successful the battery light will flash 3 times within the next 15 seconds
5. BMS reset completed

Hope this helps

If it has 10v or less it has a bad cell

Thanks all for your thoughts and insight. Sadly I'm more concerned about her safety on our freeway system than I am about her being deployed to Kuwait. She's a very capable grown woman but still my little girl. The battery in my truck died this summer with little or no warning and that seems to be how it is now.

Her truck has the start stop feature and a slew of electronics on it so I'm going to whip out her debit card and buy the battery. I've noticed how the prices have jumped immensely but that's everything anymore. So I'll pick up a battery down there in Ga, swap it out and take t he core back. The Ford dealer is a hump from her house but I have to say that I feel that they are best dealer that I've ever seen. With that said, no more MC batteries.

Thanks again all. She's at 19 days and counting from ending an eight month deployment and I can't wait to see her.

If this procedure is not successful, can it be redone?

That seems easy, why the heck do so many threads state you have to go to the Dealer? Is this something they changed on newer trucks? Thanks for that info.

Be sure to thank her for her service, from a fellow Veteran, and Im sure there are many others hanging out here.

Don’t forget to charge that new battery to 100% right before you leave. And tell her we all said thanks. Last time I was in Kuwait it was a bombed out war zone with massive burning oil wells. I'm sure they’ve cleaned it up a little since then.

Yes can be done as many times as needed

I'm not a "take it to the dealer" guy so dug and found this procedure. It can also be done very easily with Forscan adapter. Both are quicker and cheaper than the dealer. Not sure what year this change was made - I traded in my 13 with the original battery so never needed to try.
