I doubt those have the overcharge protection circuit in them like the factory battery. We have to be VERY careful charging them, anything over 14V will trip the failsafe.

Edit: not sure the car will even charge a battery without that module plugged in and working.

If you read through that entire thread, no one is reporting having those types of issues. In fact, the only real concern is low temperature starting, (which is not Lithium Ion's strong suit). In that case you would be better off going with a AGM battery, like the one's I listed in the first place.

I'm going to go way out on a limb here, and say it's a pretty safe bet there aren't many people who are going to run to a dealer, and line up to pay close to $2K for a battery to start their car.

I'm sure there are plenty of these vehicles running around with either aftermarket Lithium Ion, or AGM batteries in them, that are operating just fine.

If this is true, in a few years owners of these cars will be in for a big shock (pun intended) when their battery dies. No this isn't for a hybrid system but the regular 12 volt starter battery. https://www.bmwpartsdirect.com/oem-parts/bmw-vehicle-battery-61218047221

Nobody, and I mean almost nobody buys their replacement battery from a BMW dealership.

It almost ranks right up there with the Bugatti Veyron $21,000.00 oil change.

Indeed. It's like buying tires at the dealership. Who does that???

Guess you don’t work at a dealership.

Considering these cars first came out in 2021, and are still under warranty, why would they have been replaced except under warranty? I have replaced one because of the overcharge issue. Lot guy boosted it from another car.

Many times. My local Toyota dealer sold tires for less than the tire shops around me.

Seems to be A LOT of confusion by some in here. Roofless pretty much explained it.
1. The OP = Shows a BMW LITHIUM BATTERY
2. Lithium batteries have NOTHING in common with AGM or Flooded Cells
3. AGM and Flooded cell batteries are both lead acid, in fact most people have AGM batteries in their car and dont even know it. If its a completely sealed UNVENTED battery it is AGM. No big deal. Nothing special about AGM, both types of lead acid do their job but with a sealed battery you dont have to worry about the level falling.

BMW = The batteries DO have chips in them, even the later models with lead acid batteries. The chips inform the computer what type of battery is in the car, the cars computer then knows how to charge the battery. Weather you get a lithium battery for your BMW or a Lead Acid, for the battery to correctly charge the replacement should be one with a chip. (or possible even charge at all)
Not a big deal and honestly $1500 for a battery from a dealer, keeping in mind its lithium (and a BMW) doesnt sound out of the ball park for a high end car.
Ill get some clarification from my son if the batteries are interchangeable since they both have chips. He has two BMWs and I know he just replaced one in a 2015 that he owns and he made some mention of a chipped battery. HE works for BMW.

Oh gotcha. Didn’t realize that.

Wet cell vs AGM would be the same though?

closer, but not identical. But alternator voltages aren't ideal for either most likely.

Must be a Canadian thing?

But they can be. That's the point of BMS

Apparently quite a few people do.I was at my Ford dealership last week and they had more tires than Discount tire on hand . Might be the Michigan roads situation also . Freeze , thaw , rain and snow all in 12 hours .

 

[mightymousetech]

Must be a Canadian thing?

Possibly. We are currently bringing in batteries by the full pallet every week.

All that is true. No one is denying it, or trying to say otherwise. The question is, will all 3 of these batteries, (flooded, AGM, or aftermarket Lithium Ion), work in said vehicle, and charge correctly? Or else be made to?

Again, most people are not going to relish the idea of spending $1,500.00+ on a car battery from a dealer, if they can successfully substitute it with a $200.00 AGM from Autozone.... Unless they're nuts and like to flush money down the toilet.

Sure, the flooded or AGM battery most likely won't last as long, and it will weigh more, but it costs $1,400.00 less. That buys a lot of AGM batteries.

I just replaced the original AGM battery in my Jeep Grand Cherokee after over 6 years. My local Chrysler Jeep dealership quoted me $400.00 and change for a new dealer installed AGM battery. Autozone wanted $209.00 for one with more CCA, and an equal warranty. And they even offered to help me with the install if I brought the car there. Guess which one I went with?

Again, the question is are these cars that specialized? Or will they operate properly with a battery that costs 85% less?

And don't even get me started on the 42V Lithium batteries that are liquid cooled. What a PITA to change.

 

[Dyusik]

Lithium definitely charges differently from AGM....

I'm curious about that. I have a lithium in my bike, had it for probably 6 years now. Never gave me grief, no signs of imminent death, even after sitting for well over 6 months untouched.

 

[skyactiv]

With strict CAFE requirements in the near future, don't be surprised when many more gas vehicles have a lithium starting battery.
The auto makers, or should we just say vehicle makers, can find suppliers and buy them at a fraction vs the aftermarket replacement cost.

Ford will save some weight and use it to their advantage to market the 2025 F150 as having the highest towing capability in it's class.
