PORTOFINO INTELLIGENT BATTERY ?

It’s normal. It’s not charging the battery if the battery doesnt need to. This saves on emission and frees some power.

My Portofino and 488 do the same. Seems it’s normal!

 

The battery itself is not intelligent, but there is a sensor connected to the battery (IBS, Intelligent battery sensor). It measures battery temperature, current and voltage).
this information is sent to the Engine control unit which uses this to determine the state of charge of the battery. It decides what the target voltage of the battery should be and communicates with a smart alternator and a voltage stabilizer ECU to determine what the system voltage should be.

 

1) That charging behavior is normal.
2) The best battery for the Portofino is the Braille lithium I48CS. (for $2500 it ought to be). That is what I will buy when my original battery needs replacement.

 

Unless you really want the lighter weight, the Braille B7548 is an equally good option. As an alternative, the cheaper Antigravity with built in booster function seems to be a great lithium option too.

I had the exact same issues over the past 2 months on my 2019 Portofino. I had to have my car jump started 5 times after running errands. It always started fine coming off the tender. When I took it into the dealer they said that I was just under the required mileage to have the battery replaced under warranty. The car was then driven the requisite number of miles and the battery was replaced. I just got it back last weekend. Fingers crossed the new battery holds up better than the old one.

 

OP Its a smart alternator not battery. And here you go all the problems start. Keep it always on tender . Drive her. But even then YOU WILL BE STRANDED.

First up throw out the Factory battery and get a new one. And get yourself a starter. You will thank me.

I just bought a brand new Portfofino. It is 2 weeks old. I haven't driven it for last 8 days. It was parked without the battery charger. This morning i went to drive it and it is completely DEAD. The dashboard comes on, but wont recognise the keys & wont start. Is this normal ?

This is my first Ferrari. I expected it to last at least 2 weeks without needing to be on the charger. Is that not the case ? Does it always have to be on the charger ? Or should i take it to the dealer & complain about a fault ?

 

Not sure how many licks it takes to get to the center of a tootsie roll tootsie pop or how many days it takes to drain a battery on a Ferrari but it’s best to always keep your battery on a tender. Maybe you could go a week or so, certainly a weekend, unless it’s an older battery (3 years?) but there are countless threads on FChat telling you:
1) keep it on a tender at all times
2) get a good Interstate battery
3) get a Noco boost (or similar) jumper because it’s not if but when
4) or spring for a Braille or similar lithium battery and not worry so much about items 1) - 3).

Thank you for your reply.
The car is 2 weeks old. So i was surprised this happened so quickly. I now have it on the tender in the garage & just ordered a Noco booster.
Guess its just part of the Ferrari experience ?

 

Complain to your Ferrari dealer, they may fit a different type of battery as a replacement. They did this a month ago with a friends Portofino.

If it still won’t start you will need to call Ferrari assist out.

Please can you tell us when was your car made? I did not know new Portofino's were still being made? What I am getting at it could have been sitting around for a while, but it still should have been fully charged when delivered to you.

 

You raise a very good point. It was made in March 2020 but sat in the showroom for 6 months b/c of Covid lockdown in the UK. So it is quite possible i'm experiencing these problems because it hasn't been used for 6months until i bought it. It had 40 miles on the clock when i took delivery.

 

A tech article in FORZA points out that starting a Ferrari with the battery low can damage electronic components.

 

Its a "simpel" thing....
(after 35 years automotive technical trainer): The battery is sulfateted (Sulfa gets in the plates and cant get out)... The inner resistance of the battery gets to high and the current it can take gets low... also the the current it can give while starting is reduced by that higher inner resistance.
So the problem is in your battery. To long standing stil is not good!
Your battery is a EFB, Enhanced Flooded Battery ( the 2 other sorts are the simpel SMF (Sealed Maintanance Free) and AGM (Absorbed Glass Matt).
the second part is your generator and electroncis. The ECU measures the state of health (STH)and state of Charge (STC)...This is done in combination with the battery sensor on the minus of the battery. The ECU decides how high the Voltage of the alternator will be. If charge is needed it wil increase Voltage to charge... the battery voltage will rise and the alternator voltage will drop. If the battery is to SMALL then this will be intermitting, every 5 sec or so.. Your battery has not been changed, but the inner resistance is so high that with a small charge the battery Voltage will rise very quick...the alternate Voltage drop.. the car consumes energy from the battery and the (to small battery because of sulfateted plates and therefor small surface of the plates in the battery...So very fast the battery Voltage drops and the ECU respond with higher charge Voltage... The system is responding very well and fast! So your system is ok!!
Your battery is gone.. simpel battery check will show you.
You can buy 2500 dollar battery's but its not necessary.

Why is your battery dead within 2 weeks of standing ? Because the draining current in rest is to high. You can measure that and it should be under the 50mA or if the battery is bigger then 100Ah, it may be a little higher. 2 weeks is a normal "standing" time.
Lets say (i don't know the battery specs of a Portofolio) the battery is 100Ah. It can start with half the capacity. Thats 50AH! So you can consume 50Ah in 2 weeks.
2 weeks is 336 hours. If you consume 140mA it will last 2 weeks... ( a brand new and fully loaded battery!!) Normally the AFB battery is not fully loaded (thats a strategy of the battery management system) .. so 50mA will take only 336hx0,05A=17Ah .. still left 83 with a margin of 33Ah!

Short version: your battery is sulfateted! Buy a new one

Sorry for my bad English, but I'm sure your Dutch is far worse

 

Bedankt voor de informatie! Ik vind het heel gemakkelijk om mijn tender in te pluggen met de magnetische buitenpoort!

 

is your account being hacked or so??

 

1) Your dealer should give you a new battery. If he won't,buy one.
2) The car should start after sitting for eight days without a tender,but it would be best to put it on the tender first and bring it to a full charge before starting.

 

Thanks for everyone's comments & advice. I put the car onto tender for a couple of hours & it started up fine. Took it for a decent drive to charge up the battery. Now keep it on tender & it seems to be ok. I think Wheels1 was correct. It has been sitting in the dealer showroom for 6mths + and hasnt been driven. So i am hoping the car just needs some bedding in.
