Battery recommendations?

For those who have used AGM batteries, don't you have to change the battery management settings in FORSCAN?

I've used Costco interstate batteries for my cars and have had 0 issues. Plus the price is great.

Right after replacing the battery, I went to the dealership to get an oil change and had them do the Battery Management Reset at the same time.

Easy to do yourself:
To reset your Mustang's Battery Management System (BMS) after a battery change, perform this quick manual sequence:
Turn the ignition to the "ON" position without starting the engine. Within 10 seconds, pull and release the high beam headlights 5 times, then press and release the brake pedal 3 times. The battery light will flash to confirm the reset.

You probably should since an AGM battery is more sensitive to overcharging. I'd think it would work without changing parameters but might affect battery life. Sorry, I can't help with the actual changes that need to be made.

All true. But that just tells the car BMS that it has a new battery. Not that the battery chemistry changed. For optimal battery charging and life the BMS operating parameters should be tailored for the battery chemistry. Since our cars came with a flooded battery that's what the BMS is programed for.

Sam's or Costco have good batteries at unbeatable prices. Christ I sound like a commercial.

I followed up by asking the guy at my local Costco how many battery warranty returns they normally get. He stated he only knew of two returns this year, and both were near the end of the warranty return period. I guess that is the other end of the spectrum.

Interstate is the worst of the worst and you spend more time warranty replacing them then having it installed. 6-12 month batteries if your lucky. All local shops have stopped carrying them because of how bad they are. Talking 100s warrantied per month per shop for the semi large shops

I had a red top laying around so I used it. Been in there for about 4years now. No forscan changes just a bms reset

My original battery died after 5 years. I replaced it with an OEM battery, and I'm on year 6.

Globally, there are hundreds of battery companies, but a select few dominate the market. In North America, nearly all 12-volt car batteries are made by just three major manufacturers: Clarios (formerly Johnson Controls), East Penn Manufacturing, and Exide.
These three manufacturers produce batteries for dozens of retail and private labels, meaning the exact same battery might be sold under different brand names.

• Clarios: The largest domestic manufacturer, supplying brands like DieHard (Advance Auto Parts/AutoZone), EverStart (Walmart), and Interstate.
• East Penn Manufacturing: Produces the Deka brand and also manufactures batteries for O'Reilly Auto Parts.
• Exide: Manufactures Exide batteries and supplies many NAPA and Champion batteries

You have done your research. After a series of battery failures (new batteries lasting less than 18 months) I got pissed and realized even though they were branded differently they were all subsidiaries of Johnson Controls. As part of that research process I discovered East Penn batteries and am now a big fan of their products. My first East Penn battery is now at 4.5 years. You generally know it is a battey made by East Penn as it is made in the USA and will say it somewhere on the label (ie their factory in Eastern Pennsylvania)! My only issue is they can be harder to find as you get farther from Pennsylvania (batteries are heavy to ship) and closer to Mexico.

Yep. Pretty much any battery will do. I think WalMart has a pretty good warranty on theirs as well when it goes bad.

Yea. I only got the 2 year warranty because that was all they had in stock when my stang wouldn't start or jump yesterday. So really had no choice unless I wanted to call my insurance or AAA to bring a batter out but that would probably been at least $350. It was $126 for mine with tax, but I slipped the tech a 20 because he had to walk way out in the lot and it was very hot and didn't make me wait. If the battery is still kicking at the end of the 2 yr warranty I will replace it with a better one. I always use heavy duty down here and good batteries.

I'm in Houston. I don't know that I get much more than 3-4 years out of a battery in a daily vehicle thanks to the heat. My car lives on a tender and seems to do better. I need to get better about checking water levels in the battery, which would prolong life. But since most batteries are under warranty for the same time period, I've had really good luck getting warranty replacements.

The company I work for uses Deka batteries almost exclusively for the generators we produce, so I'm probably going to go that route for the Mustang when the current Interstate gives up. This Interstate is only the second battery my car has needed though, and it's been installed since Dec '20. Problem is finding someplace nearby that carries Deka, looks like I would need to have it shipped. Looks like Ace carries the brand, but I can't find the specific model for our cars.
