Battery replacement

You do not need to put ypur car on the charger, in fact it is ill advised to do so when messing with the electronicts. They are very sensitive. Just disconnect your battery, install and connect the new one, and follow the procedure in your owners manual. It's all there and very simple.

Good luck

 

Placing your car's 12V circuity on a battery tender that usually puts out 13-14V of current depending on ambient temperatures makes no sense at all as your car battery acts as a 12V protective filter for your car (besides supplying 12V current). You will likely destroy many circuits if you hook up 13-14V power to a circuit that works on 12V. This is basic knowledge for any car mechanic.

Also, if you have a European or a HELE-equiped car you need to know how to reset the HELE system afterwards and those instructions are NOT in the owner's manual.

Don't work on your car if you have no relevant experience, skill or understanding of how your car's systems work - have it done by your dealer.

 

If your car has never exhibited stop-start function it likely doesn’t have HELE. Very few cars in North America has it. However I assume you bought it used so the best way to check is to locate the original dealer and ask them to confirm using the VIN. Ask them for advice on battery but don’t do it yourself because it looks like you haven’t changed a battery yourself before. This is not a good car to experiment with.

You should always know what you are buying or what you own. You should have the paperwork for your car.

 

There is a dealer in Tampa, where you are.

 

Good luck but be aware this is not an "old car", at least in terms of technology.

The Cali was the first of a big jump in terms of software and hardware technology even from the preceding Ferrari models. If you accidentally damage the car, both the Ferrari parts and dealer labour can be very painful to absorb. To repair Ferraris built in the last 15 years you need to own an expensive diagnostic computer. These are not cars you can cheaply and safely tinker with.
