458 Battery how long off the tender
Discussion
Bit of a long story
Had my 458 coming up to a year, it was supposed to have new genuine Battery when i took delivery.
Its never sounded quite up to it on 1st start up, its always been on the Ferrari tender.
Any who, December time it was cold, as i said always on the tender, tried to start it and it struggled and came up with "electrical fault go to dealer"
It was due a service so mentioned it, they said all ok, off the record dont use the Ferrari charger, so swapped to a much beefier version, if i m honest it still sounds the same when you start it.
Fast forward to today, the last time i used it was 10 days ago and on purpose i did not plug it back in, again i had the same issue as in December it only just started and flashed up the same "go to dealer" used the car just fine and is now tucked up plugged back in.
My questions are this
1: How long can you leave it off the tender ?
2: Looking at a replacement, anyone got any recommendation
As a side note, in December i did some tests, battery voltage 12.50V dropping to 11.20V on cranking.

I have done a fair amount of reading on this topic. I posted tech note on FerrariChat
https://www.ferrarichat.com/forum/threads/tech-rev...
I have read estimates of shutdown currents of 40 – 75 mA based on whether the car alarm is set or not. Depending on the state of your battery you many only have days before the voltage drops below 11.5V after which you will have issues.
Thanks for this, a good read https://www.ferrarichat.com/forum/threads/tech-rev...

I was going to up-date this.
Took a trip to Spain in the 458, took a Noco Booster pack with me encase, any way 4 days in hotel car park off any sort of charger, had the same lazy start issue, drove for around 20 minutes and the warning come up "Engine Control System Failure" Ignition on and of did not remove the warning, car felt and drove ok, drove it back home some 600 miles all ok.
Disconnected battery for 10 mins warning gone, put is back on charge, next day same Lazy start. dash lit up like a Christmas tree !
Took the battery out and had the date on it of 22 Mar 2019, i got the car July 2020 and it was supposed to be a new battery, called up JCT600 and they explained that it's just the manufacturer date. A bit of messages back and forth i ordered and new Battery (Odyssey PC1220) date 23 Sep 2020 so these dates are a bit misleading.
Anyway fitted it on Sunday, awaiting to see if makes the starting better.
