    I'm going to take my car tomorrow to the workshop to change the battery; took it a couple days ago and they said the battery was weak. Apparently they need four hours to replace the battery and a couple of days to send the data to Ferrari and insure everything is good to go. I was wondering, hesitantly, if I disconnect the battery myself and then connect it again, the gearbox display might reappear.

    Should I attempt fiddling with it and see if it works? Or will I just ef' things up even more lol. Is it that complicated?

    There's a quick-disconnect at the positive pole. Disconnection is a matter of seconds. Why not give it a try...

    I would leave it alone since you are going to the dealer tomorrow. If there is a problem in the system, i.e. a short of some kind, you may have a spark at the positive pole when you try to reconnect it. Perhaps it may be harder for the dealer to diagnose the problem if you are successful in resetting things? Thank for sharing your experience!

    This may make me sound like an utter noob, but what is a 'positive pole'? *ducks*

    I ended up not going to the dealer today; the car was fine and my gearbox display worked fine...knock on wood. Does the battery recuperate itself a week or two (cause that's what I feel like it happening) after being not driven for a couple of months?

    I spent quite some time with the manual but it doesn't have an 'idiot guide' aka NO PICTURES for battery disconnection :D

    There's plus ➕ and minus ➖ at the battery. The positive pole is the one with the ➕ on it (the left one ;-))

    I figured that would be it but given I failed physics and maths more than a couple of times, I thought I'd shut up and see what the experts have to say ;)

    Thanks mate! Will start fiddling away

    Driving your car will recharge the battery. The longer you drive it, the more recharging occurs. It takes quite a bit of battery power every time you start your car. And it takes probably something in the range of 30-45 minutes of driving to make up that lost charge. If you take many short trips, over time, you are basically losing charge. The solution to this is: 1- take longer drives = :) ; and/or 2- use the battery tender.

    If your battery is not holding a charge and the car is fairly new, there is always the possibility you just have a bad battery. It does happen. We've had a few cars that came with bad batteries over the years. So far this hasn't happened in a Ferrari, but its really the battery supplier and not the car manufacturer. The dealer will have equipment that can diagnose if the battery is truly at fault. If it is, replace it. If it isn't then make sure to use the tender when you are not using the car. My rule of thumb is to plug it in after each use because I am a busy person and my plans frequently change. I might think I will drive the car the next day and then things change and I don't drive it and then I have forgotten to plug the car in. You can probably go a week or so without plugging it in.

    The car will naturally drain the battery if left undriven. When you start a Ferrari with a weak battery the charging system then goes into max output.
    Why stress the system like that?
    Attach the Battery maintainer to the Ferrari so everytime you want to drive the battery is topped off and you're ready to go.
    Battery life can also double with a maintainer. I'm not sure what Ferrari might charge to change your battery, but I can't imagine "inexpensive" would describe it...
