Second Thoughts

[Chris_G]

The truck doesn't have any problems related to deep-sleep, it's just a byproduct of the extremely small, budget battery that comes standard. There's a rumor there might be a higher quality battery coming in place of the current "Enhanced' Flooded Cell being used in the Hybrid.

Only been a few days, however the difference in how mine charges and maintains both voltage and SoC after swapping out the Motorcraft with the Weize AGM H5/47 battery is night & day different. - It does actually bring the battery back up to the post-drive state, even on a somewhat shorter trip in cold weather with the heated seat, wheel, and lights all on.

Don't worry about your order, just figure you might want to upgrade the battery at some point, either with a higher quality 99/RT4 or H5/47 (former is same physical size, latter is physically larger).

I just ordered the battery from Amazon.
Tired of keeping the Battery Tender on the truck.

Open for suggestions and help.

Thanks!

Hybrid with lux and 360 on order (Jan 24 build date) but having second thoughts. The deep sleep/battery issue greatly concerns me. I live in northern Maine and will be mostly using the Mac locally for short trips, often less than 10 miles. While the truck will be parked in a heated garage, from what I have been reading I may experience the problems that so many have faced. I ordered the heated seats and from what I am reading on the forum, using them might be problematic. Your thoughts please.

I have a early hybrid Lariat with the lux package and Co pilot. My Mav will be 2 years old on 3/9/24. I have less then 7K miles so the truck stays in the garage up to 6 day without going anywhere. I never had a problem with the truck not starting, even though it often sends me the notice it's in deep sleep mode. I got use to all the clicking sounds, that bothered me at first but now I take them with a grain of salt. Don't let all the problems people claim on this site worry you, yes, you will have some, but Ford will straighten them out when you go in for service. Love my Maverick.

The main reason for doing this is the $120 AGM battery. This is a great upgrade, almost doubled reserve capacity.
BTW, battery reviews are great

The Type 47/H5 battery will fit the enclosure, with two caveats:

1) In order to actually get the battery into the area it is necessary to pull off the right (passenger) side of the surround. The back threshold and compartment pieces just pull out by tugging on them to release the plastic clips. Thankfully they pull off and snap back in quite easily.

2) The battery tray as two raised lips or tabs which are bent upwards to hold the factory battery from sliding. (Really aren't needed, as the 'wedge' or clamp provides more than sufficient force to prevent movement). To prevent possible damage to the bottom of the H5, I knocked/tapped them down flat with a small hammer. - They're just the sheet metal of the tray which was formed/bent up during manufacture. Others have cut them off, I chose to just knock them down with a hammer. I didn't try it, however there might be enough room to simply add some padding between those two slips to create a flat surface and still have it fit, they can't be more than 3/16th of an inch in height. (If you try just making a flat area with a piece of scrap, let us know if it does fit).

Once the H5/47 battery is in place, snap the two plastic panels back into place, put the cover on, and you're ready to perform the BMS reset. (Ignition on but not started, flash high beams 5x, tap brake 3x within 10 seconds; battery icon flashes to indicate reset; lock the truck and let it sit for 8 hours while it relearns the battery).

If you have Forscan (or know somebody with it), it's helpful to set the battery type to 60amp/H5 case before the BMS reset. The truck *should* learn the battery, however setting the battery type & size from the pull-down will aid it greatly. (60A/H5 is one of the options in the menu). - FWIW the default size is 'Unknown' or 'Unspecified', it isn't even set to the 43A/T4 option, but is configured for AGM, so go figure. (The other option other than 43A & the 60A H5 is 60A H6, along with unspecified).

The Weize I used was considerably heavier than the factory 99R/T4, and weighed in close to 10 lbs heavier. With batteries, usually heavier is better, indicating larger plates inside the battery.

Hi @cyberdog ,
What menu is the battery setting in?
My battery is charged and waiting install this evening. BTW, the battery was packed well, seems like one hell of a great deal, thanks!

It's done yes, body module it was set to AGM as others mentioned. Set charge to 90

Battery settings are under BdyCM, going from memory for anyone who needs to find it. Not my image, one copied from another thread.

Forgot to add, mine was also set to Incorrect Value or Not Set before I changed it to the 60AH H5 Case. - Possibly due to the BMS relearn I'd done weeks earlier, or that's how they come from the factory, which might explain the odd charging nature, who knows.
