Portofino Battery Charging

When you attach the battery charger, the light should change from blinking red to a yellowish light and then green when the battery is charged. Suggest try re-seating the charger magnet until the light stops blinking red. Sometimes it takes me a few attempts to get the magnet properly seated.

 

Yes, sounds as though there is a connection issue

When the tender is connected properly (connector seated into place,perfectly vertical),the red light will blink six times and turn amber on the seventh blink. When fully charged,the light turns green. I don't know if the tender is capable of charging a dead battery,but if it is then it will take much longer than three hours. It is a low-amp tender,not a battery charger.

 

When dealing with battery issues,read pages 171 and following in the Owner's Manual (USA version). If you need to disconnect the battery (which you should do if you want to use a real charger),remove the plastic grill at the right rear of the engine compartment by turning the three thumbscrews, and lift off the negative terminal by squeezing the button at the top of the terminal. I mention this because the description in the Owner's Manual is very unclear.

 

Have you checked the actual battery connections are all aok ? One of mine worked loose so prevented charging.

Be careful of jump start a dead battery. Don't know how similar is my 2011 Cali to a Portofino, Last month first time I jumped start it I had a fault code on the display. First it was air bag, then EBS emergency brake system and the third time it was transmission locked up. I had to call the Ferrari tech mobile service to come out had the battery replaced and OBC cleared all faults. I would try to charge the battery to full without the tender plugged in before jump start it.

 

The Owner's Manual is very emphatic: DO NOT JUMP START (page 174).

 

These cars need to be on a tender whenever they are not being driven. Once, our GFCI outlet popped, and after a couple of days without benefit of the trickle charger we had problems opening the roof. The computer is a constant drain on the battery; therefore the battery must be "maintained" by the trickle charger.

 

My car is parked where I can't leave the tender connected all the time without worrying about someone stealing the tender. I use the tender after driving the car (which can take up to three hours to show green) and then every other day (which takes an hour or less to show green).

 

Did it sit for two weeks without being plugged in?

 

Are you asking me or OP? OP's post indicates that his car was not on a charger for two weeks.

 

Yes, drive it as often as practical, tender otherwise. Also, get a new battery tender while you're at it...T

 

Why not just save yourself all the hassle and buy the best AGM battery you can find?

In other words, get a Braille B7548.

There is nothing odd about your experience. The stock battery is utter garbage, and after it has been discharged, it will never be a battery again.

Do it once, do it right.
