Ford will tell you to drive it more. I would recommend a battery tender if you only drive once a week. These new cars and pickups are computers on wheels and demand more electricity.

Road trip! Not sure if it was an update or what, but no more deep sleep messages. I got about 15-20 the first year. Never caused any issues even with the messages. Same battery but DS just kinda went away.

I'm telling you the requirements of our trucks require this type of battery. You need the 600CCA - AGM H5 Group type of battery. Get this battery, reset the BCM and be done with it. This will save you trips going back to the dealership and them installing inferior batteries and telling you to "drive more" and you scratching your head with more sleep messages 3 months later even though you drove from Florida to Oregon and back. So much has been wrote on this. Yes, you will have to buy your own battery. But in most cases the AGM batteries are cheaper that a high grade flooded battery. And you will be DONE with this mess. Won't need the trickle charger, do-hickey set ups or the need to hard charging the battery every 3 months. You will be done, and happy and able to drive and enjoy. Best wishes to you!!Under sized 12v battery..
Check Walmart...

I am in a similar situation - drive the truck only about once a week, it would go into deep sleep mode often. It always started up so I just lived with it. I also tow the Mav behind my MH and on a recent trip I went to get the truck ready for the day and found it completely dead. I ended up buying a new battery from NAPA and resetting the BMS. The truck no longer goes into deep sleep. Not sure if the new battery or resetting the BMS was what fixed it. In 20/20 hindsight I would now try resetting the BMS after fully recharging the battery. I did recharge the OEM battery and load testing shows it to be barely good, it is now a spare that I will carry in case the NAPA battery goes south.

Agree 100%. Replaced the crappy Ford battery (which they replaced FOUR times, always having the same issues still) with a Diehard about eight months ago, with no problems since. Hated having the pay out of pocket but in the long haul it was for the best.
I assume this battery fit ok? I see that the width is 9-9/16" vs the stock width of ~8".
I was looking at the Die Hard Platinum AGM H5, also 9-9/16" wide, but not sure about the vent location hookup...
The DieHard Gold Battery T4 (not AGM) is also on my list, it's closer to stock size at 8-1/8".

Does this battery fit properly under the seat with the plastic cover on?
Does this battery have a vent like the original battery does to vent toxic fumes to the exterior?
Is this battery still available?
I ask because I only see the 680 cca version.

Has anyone tried this battery?

I have the Die Hard (Non-AGM) T4 470 CCA 585CA 70 minute reserve. I wasn't aware of the AGM type batteries until after I purchased it. To answer your question, yes to all questions. Venting can be done. Others have done it. My Die Hard battery lasted 4 months till I got a "deep sleep" message. So I did a full charge on it and reset the BCM. Christmas time I will get the Interstate AGM 65-48/H6 760CCA battery, fully charge it over night before installing it, I'm going to buy the Forscan thing-a-ma-bob, reset the charge percentage to 95%, install the battery, reset the BCM and then I should be completely done with this mess. Yes, I will have to invest around $300 to $400 dollars, but my truck won't die on the road, I won't get sleep messages and I won't be making trips to the dealer to convince them otherwise. In other words..............."That be all".
There are various threads on this. People have made it work. I can't describe it in a sentence. Best I can say is to put in the search bar AGM H6 battery install or AGM battery install. I have seen photos of people cutting the plastic around the battery area and installing their own mounting housings.
