296 GTB. died

Ouch!… how many miles have you done?… and do you keep it plugged in when not using?…

I noticed in my GTS Ferrari have replaced the 12V Li-Ion Low Voltage (LV) battery with a traditional gel type battery (without mentioning it apart from a loose piece of A4 tucked into the documents! Which I’m sure most owners wouldn’t notice. The manual still mentions Li-Ion battery!)

I wondered if all 296 will now have this because of poor reliability/ performance with the Li-Ion battery. Do you know which battery yours is?

Anyway hope you get it fixed without too much difficulty. Do keep us posted.

 

I think that is what Ferrari call the Low Voltage 12 V battery - in the passenger footwell. As can see it is a traditional old fashion lead acid battery which should be fairly reliable. These used to be Lithium Ion as well but seems Ferrari have reverted to using a traditional battery.

From the messages and pictures you posted it does sound like your issue is with the hybrid system which would be more complicated.

Take a look at the SF90 forum on this site as there have been posts about a few failures there.

 

Not confidence inspiring. I would not have made it home from the dealership at that mileage.

 

I'm surprised there isn't an electrics bypass mode that defaults to the ICE engine only for cases like this so one can at least limp somewhere.

 

Some info here my help.

Good luck.

The low voltage battery and high voltage battery are connected in sequence from what I gather so there is no way to go into a limp type mode if there is a voltage issue on the low voltage battery. The charging cable supplies power through the low voltage battery and then on into the high voltage battery. If the low voltage battery drops below a certain voltage the system starts having problems and then shuts down to protect itself and the high voltage battery. You end up with a completely dead car as the low voltage battery controls all the usual systems - starting, dash display, central locking, windows, lights etc. The car requires to be locked whilst connected to the charger so if there is a failure you have to gain access using the emergency metal key. I strongly advised that nobody keeps this emergency key in their glovebox. Either carry it with you in a wallet or keep it in a safe place in your home. You must also not charge the car using an extension cable. It needs to be plugged direct into a mains supply.

I was told the system is sensitive to any spikes in power delivery during charging. The MyFerrari app alerts you to the battery status and will send an audible alarm if it is not charging. I got rudely awakened at 3am one morning by the app as it sent me multiple alerts warning of various failures like the ones in the OP above. I thought it would be fine if I left it until I got up at 6:30am so muted my phone. I was wrong. By the time I went to check on the car it was totally dead and I needed to call Ferrari Assistance. It seems that the battery discharges itself very quickly. It was plugged in and on charge when this happened. I tried disconnecting the charger, moving it to another wall socket and restarting the charging process but the car wouldn't accept it. Ferrari sent out a recovery truck and the truck driver was relieved to hear that I had not kept the emergency key in the glovebox. He said I'd be amazed how many people do this. My car was one of the early ones so was fitted with the lithium ion battery and Ferrari instruct you not to jump start one of these batteries. I believe later cars have switched back to lead acid batteries from the factory with supply issues being cited as the reason for this change. The recovery driver had to put the gearbox into manual mode using the special tool in the car's tool bag and we then pushed it out of my garage and into a place where the truck winch could pull it onto the truck.

The dealership couldn't find any issue using their diagnostics once it arrived with them and they and recharged it. The problem did not re-occur so I have to assume it was triggered by a power surge on my electricity supply or was a glitch. The concerning aspect was that the dealer could not fathom why it accepted a recharge using my charging cable in their workshop but wouldn't at my house that same morning. It charged correctly once the car was delivered back to me with no further issue.

 

summary:I thought it would be fine if I left it until I got up at 6:30am so muted my phone. I was wrong.

 

And here I thought my electric Cadillac was the only one with this type of issue. Have a 296 coming. Twice the fun.

 

our li ion 2023 range rover battery died the last night of our hotel stay on vacation. possibly the side mirrors weren't completely closed and the car kept trying to close them and finally went into limp battery protection deep sleep mode. a valet's hummer battery conventional jump didn't work, but the tow truck driver used a li ion battery jumper when he arrived and the car came to life in a millisecond. he says these new rovers have that happen alot. dealer couldn't find anything wrong later. don't be fooled. you can jump start those new li ion batteries but you need to use a high amp sump starter (which i and many new range rover owners now have). i'd carry one. what are you supposed to do in the middle of nowhere with no cell service?

 

Ah, the good ol days. Where have they gone? Red to Red. Black to Black. DONE!

This is just one of several reasons why my F8 Spider may be a forever car.

 

I cannot imagine how expensive these things will be out of warranty. When you do a PPI on a normal car, you can look over everything. You can collect information about the condition of the engine and gearbox. How do you know in a hybrid if some electronic system, motor, or battery is about to fail? And in the case of these cars, low mileage may be worse than high mileage.

We are entering a brave new world.

 

As mentioned above I can confirm they have reverted to lead acid battery in my July 2023 GTS… your comments are helpful and at least sheds some light on why they changed … with the older ICE cars the 12V batteries also seemed to be a joke (Li Ion) … flat within days

 

My GTS also has a leaflet stating it does not have a Li-Ion battery. Not sure about my GTB.

The GTB generally states about 42 days of autonomy on the battery (on the my drive screen).

I leave it plugged in though and do not have any issues.

 

Probably still too early, but I'm curious to what the dealership has to say.

I have a feeling we are going to see a lot of issues with the 296

 

My GTB lasts 10 days before I have to charge or drive it. SF90 has no problem what so ever without charge for 3-4 weeks
I suspect the battery size or quality differs.

 

Is the LVB the equivalent of a 12V battery in an EV? Those are notorious for discharging and rendering a car useless until recharged. Perhaps you can connect a battery maintainer to the LVB to keep it charged?

Yes, the LVB is the 12V battery that runs all the normal functions in the car in the same way it does in an ICE car. The high voltage battery is the one that powers the electric motor. As I understand it the charging cable charges the LVB 12V battery first and then feeds power to the high voltage battery.

For anyone interested the charging cable is a Ferrari branded version of a Mennekes Mode 2 type charger. https://www.mennekes.org/emobility/product-details/charging-cable-mode-2-type-2-13a-4m-vde-35201100061/

 

NOCO GB50 is your best friend. I have one all the time in my Lusso, and a GB40 in my daily driver.

 

that's what we go got. but the bigger one. because size matters.
