New Battery Not Covered under warranty

[icegradner]

Absolutely, I couldn't agree more.

Our Badlands gets driven very little -- typically to the grocery store, which is 6 miles one-way. So 12 miles r/t with the engine started twice and back home the voltage is typically 12.75V+/- (after resting a few hours).

I've read several posts in which the author recommends driving 2 hours a day (as you said). I'm not sure where that comes from. If that's the case and the battery is good, something is wrong with the charging system and/or there is a heavy phantom load.

In any case, even though our charging system seems OK, I connect a BT after it sits for a few days and the voltage decreases to ~12.6V. I wait a while to hook it up because I like to keep an eye on the rate of discharge.

The two hours a day thing is more for the hybrid, the system just doesn't charge the 12v battery properly (only to 80%), and the only way to do that is if you drive over an hour a day. Ford for some strange reason seems to be unwilling to change this. I can only guess that it's a scam to sell more 12v batteries. Other modern Ford hybrids have the same deep sleep issues, although I don't know if it is a common with other models.

They are definitely talking about your 12V battery rather than your hybrid battery. No way the hybrid battery would cost $900 lol. At the same time, $900 to install a 12V is insane. Buy the AGM one off Amazon for $150, install it yourself, do the BMS reset, and save a lot of $$$

I’ll bite! What are AGM & BMS?

Ditto to hybrid comment for the 2hr daily - just seems to be the difference between problems or no problems between drivers and how long their daily commute is.

The Maverick hybrid has a battery charger in it powered by the HVB. That's how I'm treating it now.
Can't decide whether to call it a 10A charger, which it can do.
Or a 5A charger, where it seems to spend more of it's time during a all-too brief topping charge.

But after 10 to infrequently 15 min - it's into a float charge, abouts 0.5 A supplied. No matter where the initial battery charge level was.

How long does a battery charger you've used at home take starting at 12.1 V?
3-4 hrs? Maybe 1-2 hrs on bigger charger?

Hence the problem.
Just because there's the means to use it like a big fancy battery charger - doesn't mean Ford should.

I've yet to hear of someone in EB have a scanner and report detailed SOC readings and charge rates during drives. Got some brief info.

It does seem to be an issue with other models. There are similar reports/complaints over on the Bronco Sport Forum.

Before posting above, it occurred to me that maybe the Maverick hybrid is able to travel a significant distance in electric only mode, so that the engine does not necessarily start for short trips, and therefore the 12V battery does not get charged. From what I read though, that is not the case.

Ford seems to be playing the 'they all do that' game. It is ridiculous to expect owners to drive their vehicle(s) over 1-2 hours per day to keep the 12V starting battery charged.

The Bronco Sport (all trims) has had at least 2 related recalls. The first involved reprogramming the charging system. The second was to replace the OE battery with an AGM.

We had both recalls done. The first had almost no effect. The average resting OE FLA battery voltage increased maybe 0.05 volts (12.65 > 12.70). When our OE battery was replaced it was ~3 years old and going strong, but getting an AGM for free didn't hurt my feelings.

One theory I have is that in an attempt to increase CAFE, Ford installed automatic stop/start and decreased the rate at which the 12V battery is recharged, to reduce the load on the engine.

Whatever the case, I'm gonna keep using my trusty BT. I agree that we shouldn't have to but it's worthwhile.

For the hybrid, it charges off the HV battery, since the hybrid does not have an alternator. The ICE being on does not dictate 12v battery charging. That said, if the hybrid battery is constantly at a low state of charge, that could in theory limit 12v battery charging. That would show up as a big problem for people who only do infrequent short trips.

I am still on the factory SLI 12v battery after 3+ years, so clearly it's not as bad for some people as others. I put it on a battery maintainer 3-4 times a year, but if I relied on Fordpass/Ford app for anything the constant battery saver mode would be a pain.

I suspect the real battery drain issue is the system telemetry (LTE connection) going to Ford, combined with other small phantom draw issues. It could even be chips or other cheap electric part causing the draw. Tracking down every little draw would be hard, and likely kill profitability, which at the end of the day is what Ford is in business to get. Building complex computer based systems like these on the cheap usually ends with issues, and we are seeing the results.

I detect sarcasm! Up on the top right hand corner of the MTC ( Maverick truck club) you will see a magnifying glass (), touch it ask your question, well not ask but type in your ? Then magically it Should take you to some responses, Type in BMS, or AGM Battery! It is very helpful.

Thanks for the info!

I realized after posting that I was getting out over my skis (and I don't even ski!). As a BS Badlands owner, I'm not familiar with the Maverick hybrid.

It's interesting that Ford designed it to charge the 12V battery from the HV battery. That's a good idea if done right. It requires a DC>DC charger but eliminates the alternator.

Since Ford does not seem anxious to deal with the problem, getting in the habit of connecting a BT is a good idea.

Speaking of which, I need to go out and check our battery...

No sarcasm intended. I’ve received great information since joining. Including your magnifying glass suggestion.

eh, I got 3 years of no battery probs out of my Mav, I'm retired, live in Michigan, only put about 8k miles on it a year, I seldom drive more than 4 miles, I don't drive it every day, I don't keep it in the garage, I never put a charger on it, it always started, I don't run the app, I did on occasion get the no dome light symptom but besides that it was fine. Eventually the battery died at 3+ years, took it in, they replaced the batt with an AGM for no charge other than my $100 deductible with my extended warranty.

Shouldn't have to but has anyone tried , ↓ Or similar?
Voltset 10W 12V Solar Panel Kit Portable Solar Battery Charger
Took it to the dealer first time they said nothing wrong, but they did a software update.
The 12-volt battery died again, made the dealer tow it to their service department, they install a new AGM battery (NC to me under warranty).
Approximately 6 days after that the vehicle is going in the power saving mode, at 8 +/-volts, and has done that three times now.
At this point I'm having a hard time with the dealer trying to tell me they don't have a loaner vehicle and if they can't find anything wrong with my truck (like the first time it was there) they're going to charge me, of course I told them to go # sand it is still under warranty.
From what I'm seeing online there isn't going to be a fix for this.
So, I'm just curious if anybody tried one of these 12V Solar Panel Kit portable solar battery charger Maintainer?

I have a 2024 Maverick Hybrid with 47,000 miles. It keeps going into deep sleep mode. Brought to the dealer today. They said I need a new battery so it will be about $900. Told it is not covered under warranty. I thought the hybrid batteries were covered up to 100,000 miles.

You need a 12 Volt battery. The HVB battery is covered. $900 for a AMG battery is high end robbery!
