Great news!

Well, how much driving are doing with the truck? Have you driven it in the summer yet? The length of the drive matters, particularly in cold temperatures. If you’re not driving it for more than about 15 minutes a day, the hybrid battery is probably not fully charging, and thus the ICE will not...

The question would be, why are you putting in an H5 when an H4 is the “plug and play” size and requires no mods or trim removal to replace as it is the same size as the flooded battery. The hybrid which you have doesn’t use the battery to start the engine and it merely runs the other systems...

Careful! Somebody might take you seriously here!! 🤣😂😉

Yes, they are delusional. The battery fits and has been installed by many members of the group including myself.

This looks pretty clear that you can.

I have had this battery installed in my 2024 hybrid for three months now with no issues. I don’t drive the vehicle more than 30 minutes 3-4 days a week.

WOW! Given that there is plenty of information here that says otherwise, this is going to be a major shock to many people here, myself included. Was considering a hybrid 2025 AWD because I live in WI, but I’ll stay with my 2024 since it can be flat towed.

I recommend the battery from Amazon listed in the post just above mine. I installed it and got it for $139 US delivered. Not sure of the exchange rate, so I don’t know if this cheaper or not than what you are looking at.

If that is what it takes for you to feel comfortable, by all means go for it, but honestly, living up in Wisconsin, where we’ve had some near zero days already, I haven’t seen the need to go to that extreme. I have just put in the plug-and-play H4 sized AGM and haven’t noticed voltage issues or...

There are vent holes on both sides of the battery. There is a plug in the packaging for the unused side. You simply plug the vent on the Mav that you will unhook from the flooded battery Into the AGM.

Exactly how it looks in my Hybrid too.

Do NOT believe Amazon about this. Any H4 sized battery will fit. The H4 140R battery that I bought off of Amazon fits perfectly despite Amazon saying it wouldn’t fit. Manufacturers will want to verify that the battery will fit your vehicle. It will.

The battery requirements for the EcoBoost and the Hybrid are different. The AGM works better on the hybrid because it charges the battery differently. There is no alternator and short drives (15 minutes or so) are extremely effective at charging the AGM battery on a hybrid since the battery...

Get the 140R. It is a drop in fit and requires no modifications. Ignore what Amazon tells you. It is wrong. The Hybrid takes the H4/140R. Multiple folks on this site have used the 140R and dropped it in. Once you swap to AGM, because of how AGM works, a larger battery isn’t going to help you...

The battery in the link is the exact battery that fits and has the correct positive, negative sides for the Hybrid Mav. I ordered it and installed it. It drops in and the terminals are correct. Did you order from the link? The Hybrid Mav has the terminals reversed from standard, hence the 140R...

I'll put myself in your shoes. My job was to break things for 40 years, not fix them. However, I decided to take a look at doing the battery replacement myself, and I had little issue with it. I was done in about 30 minutes and did it with tools I had on hand. The advice I've seen on this...

My Mav is my 5th Ford with either Sync 3 or Sync 4. This has happened on every vehicle. It’s is something in how Sync interacts with CarPlay and Ford is either unaware of the issue, or doesn’t know how to fix it. It’s hard to believe they aren’t aware of it, so I’m guessing they don’t know how...

I absolutely agree that Ford should be fixing it, and that we shouldn’t need to disable features. However, until Ford does the right thing, we’re stuck with either having dead trucks have their batteries replaced frequently under warranty, hooking the flooded battery up to a tender frequently...

As stated above by multiple people, for the hybrid, use the U-Plus battery on Amazon. Cheap, fits perfectly, and less than a 30 minute job to change. I did it, and then followed the instructions to reset the BMS in the Owner’s Manual and it’s worked great. Once you do it, your Mav will then have...
