Hybrid +12V Battery Replacement

[scotty]

I purchased my Hybrid 12 months ago and it has 9000 'almost trouble free' miles on it. Like many, I've been plagued with the 12 volt issue deep sleep issue for the last 7-8 months which generally manifests itself with no interior lights. The truck has never failed to start or left me stranded. The last straw was Sunday when my wife and adult daughter went to get in the truck at night and asked me why Mavericks don't have interior lights.... LOL

When the deep sleep issues start, checking the pins under the hood generally show about 11.4V and I've recharged the battery (with a high quality charger) many times, but the problem always returns. What's interesting is that my original battery would charge right back up generally within a hour....

I just hated the thought of dealing with the dealership, I know the truck would sit there for a week, probably come back with door dings and scuffs, the dealer would try to blame it on something else, etc., etc... so I decided to swap batteries at my cost, know the swap was done correctly and at least rule a bad battery out of the equation. I was also worried about getting a new, bad Motorcraft battery which would only compound the issue.

So, I spent the $220 on a new Diehard Gold with a manufacture date of last month and installed it. It's specs are exactly the same as the original Motorcraft, has the same exact provision for the vent tube, and was a perfect fit. I put it on the charger for 5 minutes to get it to 100% and swapped it.

Changing the battery on this truck is a little bit of a PITA, trying to hold the cables back, bent over, getting the hold down bracket and bolt in position and bolt started, etc... The only tool needed is a 10mm socket and a long extension (for both the hold down bolt and the cable clamp nuts). WHEN you drop the hold down bolt next to the battery (and you will, LOL) it will slide out of site and you'll need to get something to fish it back out.

When finished, I opened the door and the light came on. LOL. I went through the Battery Sensor Reset procedure with the high beam lights and brake pedal, locked the doors and exited and will let it sit overnight per the manual. I'll take a better close-up pic of the battery tomorrow, but it's shown with my Nicad emergency charger (never used thankfully)

I checked the 12V cable under the hood months ago and never felt any play or movement, however I did not cut back the insulation to check for a cold solder joint on the terminal. If nothing else, this should rule out a battery issue.

More to come

Thank you for the information. It's been a bit over a year since you went to the new battery.
How has the battery been holding up?
Was that diehard one of those AGM batteries?

One of the best and inexpensive battery that will fit a hybrid

Op here, Unless it recently changed the battery in the Maverick Hybrid is a Group T4



.

The stock battery in the Maverick Hybrid is Group size 99R, which I incorrectly cross-referenced to H4, where it should have been T4.

Good eye! I'll correct my post above, with thanks.

Note: both H4 and T4 are DIN (European) codes, they are not BCI group sizes.

OEM battery in the Maverick Hybrid:
BCI size code: Group 99R
DIN (German, so European) code: T4
Japanese code: LBN1
(most all of these are flooded type batteries)

Same physical size battery that's a drop in and can be bought as an AGM:
BCI size code: Group 140R
DIN (German, so European) code: H4
Japanese code: LN1
Make sure you get an AGM, I have seen flooded Group 140Rs as well.

Group size 99R is correct, but indeed I incorrectly cross referenced it to H4, where it should have been T4.

Do make sure you pick an AGM type though!

My battery clear says 4H on it. See my pic sent, and included in thread 238. I don't know why "H4" why its on my battery unless it was made in europe.

I have no idea either, but note that T4/Group 99R and H4/Group 140R size batteries are almost the same size and have the same exact footprint. Maybe you have a flooded type H4/Group 140R battery in yours.

Wouldn't worry about it though!

Group 99R/T4 I have yet to find in AGM (only flooded types available), and Group 140R/H4 you can readily find in AGM chemistry, but there are flooded ones too. So pay attention to what you get.

That is great to know for matching. 140R more recent it appears.

So the extra 15 mm (175 to 190 height) wasn't an issue with cover?
(I'm guessing not since the H4 for Scotty fits already).

I was wondering how much clear space under the cover since I have T4/99R.

That's gotta be the only other size with same matching footprint - great find!
I'll bet it did start as AGM standard, with FLA coming later as possible replacement for cheaper price.

I ended up installing a Weize H5 AGM battery. It barely fit in the under seat compartment, but I was able to make it work. I also used forscan to set my battery size to H5, my target SOC to 100%, and my battery type to AGM (although it was already set to AGM from the factory).

I have not had a single dead battery or deep sleep mode issue since making these modifications.

Darnon on the forum said " H5 requires removing the plastic bin panels to install and cutting/flattening the metal battery positioning tabs on the truck because it's a larger battery. "

You said "you was able to make it work" meaning fit the weize in the compartment for battery.

"make it work"oes that mean was Darnon had to do? Remove plastic panels and cut/flattening metal battery posts.

Thats to much for me. Removing panels I guess is ok, but not cut/flattening posts.

I did have to remove the plastic panels to install the battery.

I did not cut out any tabs. There was a metal tab on the floor where the battery sits that I had to bend slightly to fit the battery. I believe it could be bent back to its original place to reinstall the OEM size battery, if needed.

@HeyBales

No issue with the height of the 140R, I don't think there is much (if any) difference with the 99R I pulled out, so it is not even tight between the 140R and the cover.

Hey thank you for that information. i have 23 xlt, about 3200 miles. Got a warning message "battery low energy" something like that anyway.

What kind of battery manufacturer, group size, etc did you get? Where? About what was the cost? Did it slide down in the compartment rather easily?



I don't want to make things complicated but I'm older, almost 71 years, and I rather spend time with family then aggravation, although I will try dealer at least once if and when needed.

After that I would like to use information you can provide about questions above.

A lot depends on your dealer. Mine is excellent. I would ask dealer to install a noco genius 5 that could be plugged in easily possibly without raising hood. If you are having him service and apply updates maybe he will do at special price. If you can periodically plug in a good 4 or 5 mode maintainer three or four times a year you can extend the life of any battery installed. Extended times on maintainer can reduce sulphation and unstratify the electrolyte will help a bunch. Good luck!

Went for a couple long drives and haven't seen deep sleep issue since. Took to dealer today and they performed SSM-51449 and TSB 23-2060. Hopefully this fixes battery drain issue.

Did the dealers work on the battery fix the issue with your battery?

You didn't buy the cheapest battery you could afford but Ford did. Remember this is there cheapest vehicle not he luxury line. I have no prof but I will not be replacing my battery with Motorcraft/Ford. I see on Pep Boys they have a battery looks like the same as Die Hard, called Value grade P/N T4-470VG for $50. Not saying I recommend it but seams like a cheap test battery if you are having problems.

Has anybody bought this cheap Pep Boys battery and had any success using it?

Went to pep boys typed in the part number and result said "0 search results found.
I did the same for the word "value". the same response.

It pops up for me when I search in Value grade P/N T4-470VG
