Replacing the Hybrid's OEM 12v. Battery

[Dad]

I've seen many a thread about how the hybrid's 12v battery is woefully inadequate and after 34 months my OEM battery finally got the point where it wouldn't start the truck. Thanks to several members here, specifically @Glen Baker LLC, I found a AGM replacement battery from Amazon and installed it today. Very satisfied with the install. The battery fit perfectly without any type of modification to the tray. Took a bit of doing to remove the original . . . mostly just figuring out where the holding clamp was located and navigating the thing out of it's bed.
I tried YouTube for a how-to and wow, was that disappointing. The one I found consisted of jerky and fast camera movements, almost no instructional context, and the capper was after finally getting it out, the installers realized the replacement was too big! Good grief! Why they published that is beyond me.

Anyway, this will serve not so much as a how-to replace the battery, but more of what you should have on hand before you begin.
Naturally, you'll need the battery.
I got mine from Amazon. Great price, 3 year warranty and 570 CCA The best feature of this battery is that it is an exact duplicate of the OEM and so it fit perfectly. No tabs to bend or cut. No plastic to trim.

You'll also need the following:

• 10mm socket (this will fit the nut holding the cable clamps on the terminals)
• 1/4 drive with at least an 8" extension to get to the holding clamp on the passenger side of the battery. I recommend using a 10mm socket with a built-in magnetic holder so you can better align and hold the bolt when you try to put back in. Tough to get your fingers down in that narrow slot.
• Telescoping magnetic pick up tool. Absolutely necessary for removing the holding clamp and replacing it.
• Long blade screwdriver. You'll need to adjust the holding clamp over it's securing hole once you get it dropped in there and it will also serve to hold it down so you can retract the magnet pick-up tool.
• You'll need something to keep the negative cable away from the battery bay otherwise it just gets in the way as you try to remove one battery and put in the new one. I zip tied mine to a small dumbbell.

Remember to reconnect the vent tubing and reset your BMS after install.

One last note: Amazon will give you a message that this battery will not fit your Maverick. Ignore that. It pops up because the Maverick hybrid's stock battery is not an AGM type. It fits perfectly.

*UPDATE* Battery has been in for a week with no negative issues. One minor, but welcomed result is that the dome courtesy lights come on when I enter the truck at night. Before the new battery, they did not light up which was inconvenient and frankly a bit irritating towards Ford for lousy quality.

I've been following some of these threads due to my truck going into sleep mode now that the weather has turned colder. Same happened last year. The link you showed says it does not fit a 22 Maverick so I'm asking for verification.

I'm not one to fix things myself due to I'm not that ... how do I say ... I'm frankly afraid to do mechanical things myself because I may cause more damage than someone more experienced. Example being I had to replace the cabin filter due to a mouse getting up there and dying, and in the process, I broke a pin that holds the filter, but it didn't hinder the replacement. Can I take this battery to the Ford dealer and have them replace, or will they refuse due to it not being a Ford product, if you know?

Thanks for the write up, that battery from Amazon is what I plan to purchase when I replace mine in my Hybrid.

When I clicked on the link it said will not fit the 2023 Hybrid XLT. Not sure why since I thought all Hybrid’s were the same in that regard.

As of today 11/23/2024 Amazon has this battery for $111.99., Black Friday Deal

Obviously made in China. All of the misspellings are a dead giveaway. Speaking of dead, one of the reviews stated DOA. And the price is a little suspicious as well. I'm not trying to be critical, just really skeptical for these reasons.
I am on the verge of springing for an AGM. The deep sleep (aka battery saver mode) is on my last nerve. Anyway, thanks for posting the info and your experience.

I should have mentioned that. Amazon reports that because the Maverick did not come stock with an AGM battery. Ignore that. It will fit.

Yea. Amazon isn't always correct.

I own one it fits.

Amazon states the battery I ordered and install as not fitting as well. As you know, it's because the Maverick's stock battery is not an AGM type. I want to thank you for leading me to the Amazon battery. As you said, it fits perfectly without any modification.

Regarding the Amazon message about not fitting your Maverick: The Maverick's stock battery is a regular battery, not an AGM type which is a much better battery, so Amazon "thinks" it isn't a fit. Believe me, it is. I've update my original post to address this and I apologize for not thinking of including it.
Regarding having a dealer install: I think you're wise to recognize your skill level. You might want to check in with your neighborhood auto repair shop. Show them my recommended tool list just to be helpful. I'm sure they would be able to do it much cheaper and more timely than a dealer. And, no, it won't void your warranty. If your dealer tells you otherwise, they are unscrupulous.

Thanks for the posting this info.

$111.99 is the BEST price you will find for a Maverick Hybrid AGM Battery that fits perfect.

Thank you for your reply. My brother will be purchasing this Maverick and he's pretty good mechanically. I'll inform him on this and see if he wants to purchase the battery and make the change himself. If not, I'm sure he could find a mechanic to do the swap. Then, when I get my 25, we'll both know what to do.

Thank you again.

You're welcome. I got the battery recommendation from @Glen Baker LLC , so many thanks to him, as well.

You are most welcome. Glad I could help.

I just ordered that battery today for $111 on Amazon.
After my battery failed me the other week and my truck went haywire I'm not going to give the dealership a chance to give me another trash battery.
Good write up I will look this over again before I install it, thanks
