battery charger

[gpracer]

i have a 2006 f430; has 2200 miles on it; i have been driving it about once a week until recently when it sat in the garage for 3 weeks; it would not start; i jump started it with jumpers from my Audi, started fine, ran fine, but by next day, needed jumper again; this lasted longer as i ran the car longer(about 30 minutes); this lasted about 3 days, started fine but after driving for 20 minutes, then sitting outside in 40degree weather for 2 hours while i had dinner, was dead again; it boosted back up; i finally realized i should get out the ferrari battery charger supplied in the trunk; i connected it as instructed but the red light along with flashing green and yellow lights are on; what do i need to do next?would greatly appreciate any help

take the battery out and have someone test it or just set it on a trickle charger over night. if thats not the case then you mite have a charging system issue. alternators dont really charge the battery like people think, they really just maintain the electrical requirements that the car is pulling on.

Hi,

Get a Tecmate battery charger, it works operating from a wall plug socket.

An optimate 3SP will do the job for mantaining the battery with desulphating feature, works fine.I have been using this in my garage for many years.

Hope this helps.
