New style Roma battery charger

@56 Spider

It uses multiple colors, when first plugged in is flashing red (no sound) as it perform diagnostics and then within a few seconds, if all good (especially if the connection end at the rear bumper is sufficient) turns solid yellow and remains until fully charged at such time turns green.

If the connector loses a 'solid' connection while charging (or has dirty connectors) it will start beeping until resolved or unplugged. This can occur after it has been charging for a while, so if you hear beeping, it is likely the connector is not on solidly.

 

That is what came with my 2019 Portofino,and it has worked fine for about three years. There are two lights behind the lens: red and green. Both lights are on during charging (which looks amber) and when fully charged the red goes out and only green shows.

 

Just used to test with my new ROMA. Depending on the angle you look at the one light, it can be almost all four colors. It's not too clear if all is good or bad!

 

Will have to store ROMA for a month. Does anyone leave charger on for over a month in storage?

 

That's what a battery tender is designed for.

 

Hello guys, this charger can fully recover the battery in case of discharging? And allow the car to switch on?

 

The tender/maintainer (called "conditioner" by Ferrari) is not designed to charge a dead or heavily discharged battery. If your car won't start,you can try the tender but if it works it may take a long time (even days) to recharge the battery. The tender is supposed to be hooked up when you are not driving the car in order to keep the battery fully charged when the car sits. When the car is parked and locked,there are still devices drawing current.

 

this is what I needed to know...thank you so much!

 

the magnetic connection on the Portofino M is a prefect improvement. works flawlessly.

 

Wonder which equivalent CTEK charger model# with magnetic connector can be used ?

 

Don't have a Roma, but assume it uses the same magnetic connector as the F8 / Portofino M. I highly recommend:

STEP 1 DESULPHATION
Detects sulphated batteries. Pulsing current and voltage, removes sulphate from the lead plates of the battery restoring the battery capacity.
STEP 2 SOFT START
Tests if the battery can accept charge. This step prevents that charging proceeds with a defect battery.
STEP 3 BULK
Charging with maximum current until approximately 80% battery capacity.
STEP 4 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
STEP 5 ANALYSE
Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced.
STEP 6 RECOND
Choose the Recond program to add the Recond step to the charging process. During the Recond step voltage increases to create controlled gassing in the battery. Gasing mixes the battery acid and gives back energy to the battery.
STEP 7 FLOAT
Maintaining the battery voltage at maximum level by providing a constant voltage charge.
STEP 8 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery fully charged

 

Thanks for the prompt reply Rob!
