hello all

my 2012 fl2 battery could do with charging ; am i ok to charge it in situ without disconnecting it (dont want to re set the radio stations or clock or windows) or is there a danger of frying the electrics if i dont disconnect

No problems with mine ctec charger just remember to remove before moving vehicle

Agreed no problems particularly with a CTEC. I plug mine into the rear socket between the seats which is always live using the cigarette lighter adaptor.

Hi,
mine gets charged via tow socket if its needed.

although recently fitted a new yuasa and did not need to do anything with the radio just set time/date and windows one touch

 .
my first ever FL2 and I did keep it longer than most other cars!
But its now gone way up Norf

My 2014 FL2 doesn't have a permanently live 12v "death stick" socket unlike older models, so I have to go into the engine bay.

My understanding is the CTEK charger should have its NEG terminal connected not to the battery NEG terminal but to somewhere on the chassis. Whereas the charger's POS connection can go straight onto the battery POS terminal.

Both AGM and EFB batteries should be charged using the CTEK's AGM mode Jules

I have a Victron 10amp charger. Smart chargers will vary voltage reduce amps unit float & then there will be zero amps until the battery voltage drops to the preset voltage, then start charging again.

I have charged my car's battery & auxiliary batteries many times over the last year directly to the terminals. Actually permanently wired in Anderson plugs.



It has a 3amp low setting I can switch to using the phone but I leave it on the 10amp setting. Procrastination, mankind's greatest labour saving device!

I have made my own charging supply.i have used 2.5mm cable with an inline fuse ,permanent connection to battary terminals out to the front grill with a weatherproof connector.then another weather proof connector back to my Aldi charger.all cheap and cheerful and it works .it also mean I can check the battery volt from outside the car.

I have a charger that is almost 30 years old and I wouldn’t leave that one unattended

But I also have a new charger (5 years old) and it will Float charge

I think the new charger could be left charging for months without any bad effects



As Lightwater pointed out make sure that you have the right type of charger


Good luck

The smart chargers stop charging when they reach set voltage & will only start topping up the battery when it drops to set voltage. Procrastination, mankind's greatest labour saving device!
