Which Ctek charger best for 430 (price not being object)?

Well gorgeous day here in NJ. Went to drive F430. Dead battery. OEM charger is dead. Started researching here the last 2 hours on best chargers to replace instead of the not so good 400 dollar plus Ferrari OEM charger.

Seems the ones that come up are the Ctek 7002, 3300 and 4.3. Am I missing a better one?

Price aside is the 7002 the absolute best?

Also can I chop the charging cable off the dead OEM charger and wire it into the new Ctek charger? My 430 had the factory installed tender so it is already in place and mounted on the passenger side footwell. If I can hack that off and splice it right into a ctek I don't even have to pop the battery plate off if it can take a charge. I could not find the wire/pin schematic for the OEM plug. I see most just put the Ctek plug right on the battery. Has anyone spliced the OEM charger plug into a ctek and if so can you explain how to do properly?

Also what is the correct procedure on the 430 after a dead battery revival? Start it and let it run for 10 minutes stopped in idle with everything off (lights, wipers, ac, etc)? Anything else?

Thanks!

 

Thanks for the info! Very helpful. I was between the 4.3 and the 7002 and decided for the 7002 as it is only 30 bucks more and why not have the extra amps available?

I am due for annual service so going to have the dealer pickup the car and drop an Interstate battery into it while its there as the OEM Ferrari battery is over 5 years old. Amazing it lasted this long actually.

On another car forum I read guys warning that these things can be sensitive to power surges and also push this through your cars electrical if there is a surge. Is it best practice to put the tender on a surge protector for add'l safety? I have a whole house surge protector but put most of my electronics (i.e. computers, dvr's, projectors) on additional back UPS/Surge setups. I didn't do this for my tender before but little more paranoid now after reading all that.

 

Just an update for those in similar situation.

As noted in my earlier post I opted for the Ctek 7002 instead of the 4.3 simply because you get more amperage and it is only a few bucks more than the 4.3.

Ok so my OEM 5 year old battery was dead. 0 volts. Probably sitting that way for at least 2 or 3 weeks as the Ferrari OEM tender died and I did not realize it.

I hooked up the Ctek but it did nothing due to the 0 volts on the battery. It thought it was not even hooked up! I used one of those older larger chargers by Century ( Century 87105C Battery Charger ) to blast 10 amps into the battery as it is not dependent on seeing voltage like the Ctek. I did this for maybe an hour. It was enough to bring the voltage up to the point the Ctek would recognize it and go to work.

I left the Ctek on for about 7 hours total and the car started up. I let it idle for 15 minutes to allow the computer to do its reset thing (all accessories off). Took it for a short ride after and all seems fine. IT's back in the Ctek now to top off the battery but I think I'm pushing it to try and get more than 5 years out of the Ferrari battery so taking to the dealer monday for new Interstate battery and annual service. They will hook up the Ctek indicator eyelet setup while putting the new battery in ( CTEK 56-382 Comfort Indicator Eyelet : Amazon.com : Automotive ). The indicator lets you know the battery status via LED's.

Thanks again to everyone above again for the help and advice. The 430 is back on the road!
