Portofino battery woes

Are they replacing it with the original Ferrari battery? It is known to be not-so-good. Put a Braille in there. But the screen issue sounds like something else is wrong with the car. And even the terrible OEM battery should last a lot longer than two weeks.

 

I would get one of these - https://www.amazon.com/Antigravity-Batteries-Bluetooth-Cranking-Charging/dp/B07NSTQCM8/ref=sr_1_6?dchild=1&keywords=antigravity+battery+monitor&qid=1628863349&sr=8-6

Install it and monitor the battery voltage and crank voltage yourself

There is some parasitic energy drain killing your batteries

 

You certainly don't want to keep going through the hassle (and expense)!

 

Three suggestions: 1) Interstate MTZ 48/H6-an AGM-$283 2) Braille B7548-an AGM-45 pounds-$357 3) Braille I48CS-lithium-20 pounds-$2500.

 

He is not in the US, so Interstate is not an option.

Look into one of the following.

AntiGravity H6 50Ah

Option 2.
Varta Silver dynamic

Option 3.
Braille B7548

Last I checked, they do ship to Europe.

Sorry to hear about your problems. Even a crappy battery should last longer than what you experienced, especially since you drive the car and regularly hook it up to the tender. Hope the situation is resolved soon so that you can drive your beautiful car!

 

Just a question: were any modifications done to this car?

 

Wishing you best of luck with this dilemma!

 

As annoying as it is, I think it is safe to assume at this stage that they are trying to find a solution. This is getting toba point where it is starting to cost them real money in parts and warranty work. In other words - they don't want you back with this problem. They know at some point you will be able to ask for your money back if the car is not right, and that is no bueno.

If this happens again, demand a different battery. As long as the battery is the same type and size etc. they cannot void your warranty on the car. They can void the warranty on the battery, but not the car. The Varta suggested above is a such battery. Remember that if something happens to the car which have to be fixed under warranty, they have to prove that the battery is at fault. This is why at the end of the day so many of us use other batteries with zero issues.

Warranties in the Uk and Europe usually have a clause about it becoming void if non company personnel change something in the car.
The best thing for the individual to do is to take this change and document via phone pics or video when they put it on charge and take it off.

then when it fails again (so sorry if it does) they have a stack of photo or video evidence they can wave around and at that point the dealer will realise that if it went to court because they wanted their money back or a new car it is no longer anecdotal evidence from the buyer but time stamped and recorded that they are charging correctly. I’d also snapshot the mileage now and obviously when the battery fails again.

Dealers are far more likely to action something when they know the customer is now documenting everything.

 

I have also been surprised by the rapid discharge of the battery in my (August) 2020 Portofino. My experience has not been as serious as cyr’s but in one case my battery discharged in just 2 days after an annual service. In that case my dealer suggested that I disconnect the battery and leave it disconnected for a couple of hours to ‘reset’ the system because something that should have been shutting down automatically when the car was parked was probably staying active. I did this and charged the battery to 12.3 volts. I then monitored the battery voltage (as indicated on the dashboard) over the next 3 weeks before re-connecting the battery charger/conditioner. I understand that if the voltage falls below 11.5V, then there can be issues with the car and if it falls below 9.5V, then the battery will have issues. I therefore reconnected the battery charger/conditioner after 21 days. Has anyone else monitored their battery performance to compare with this discharge curve? I would be interested to learn whether this might be considered representative for the Portofino or whether my battery has been damaged by the discharge experienced.

In the long term (post warranty), the recommended option appears to be to replace the lead acid battery with a Lithium-Ion alternative.

 

An open circuit voltage check that yields 12.3 volts means that the battery is at a state of 50%-75% charged. The battery should read at least 12.6 volts. You'll get more accurate results if you do a load test.

I suspect you have a battery issue?

 

Thank you for your comment. For clarity, all of the measured voltages (including the 12.3V at the start of the test) were made via the dashboard, with the battery connected. The discharge therefore measures the battery drain imposed by the car's systems at rest (i.e. parked). I would be interested to see a comparison with a brand new battery installed to see if that performs any differently.

 

I have a 2019 Portofino with 11,000 miles on the original battery and no issues. If I remove the factory tender and turn on the ignition several hours later,the dash voltmeter reads 12.3 or less (usually less).

My Cali t stays on a float charger at all times when in the garage, no matter how far or long I drive it, when I plug the tender back in, it charges (red light) for hours sometimes over night to reach fully charged (green light). (Thankfully we have a magnetic exterior charge port)
If the factory charging system is in reality only charging to 12.3 V it is not fully charged and could explain the premature battery failures in the Cali t/Porto series?
Just food for thought

 

Just wait till fcars go all electric! Future looks interesting!

 

From my no-issues Portofino:
1) Car parked for two days without tender,battery shows 11.8 or so (fluctuating), with ignition on dash shows 11.7 and battery shows 11.7.
2) Car on tender,battery shows 12.75.
3) Tender removed when shows fully charged,battery shows 11.8,with ignition on dash shows 12.0 and battery shows 11.9.
4) Car driven all afternoon,dash shows 12.0 before all starts,dash shows up to 14.7 while driving.
