Using IID Tool - Do I NEED a CTEK/battery charger??
People of knowledge - I need your wisdom please.
Just bought an IID tool thats coming tomorrow - Reading the instructions, it says that I should connect a CTEK (or similar) to ensure my battery doesn't die whilst changing stuff.
Honest opinions: Do I really need one of these? They're not cheap, but I'm happy to purchase one if it's really necessary. If I'm just editing CCF's etc, can it REALLY drain the battery that quickly?
And if so, whats the best, but cheapest thing that'll do the job?
Any recommendations/knowledge would be appreciated.

alst two mods I have done I did not have car connected to my CTEK and TBH last one was a bit scary as it lasted a few good minutes
next upgrade I am defo attaching battery to CTEK
They are good investment especially these days with AGM batteries

Forgive the potentially stupid question, but I don't understand how they (IID tools) can drain the battery so swiftly?
What exactly is it that drains the battery so quickly??1964 SIIA - Gone but not forgotten

It's not so much the iid tool itself but more the fact that whilst you are using it and playing through various menus etc the vehicle needs to be in the 'ignition on' position.. Therefore things like the fuel pump, all ecu's, turbo actuators etc are all draining the battery.. Along with the stereo head unit etc (which of course you will have turned off! )
Now the issue comes when you want to flash an ecu etc which can sometimes take 6/7 minutes or more.. During which time it is essential to have a stable voltage to a) ensure that the flash actually completes and b) its doesn't fail mid flash and leave you
Generally a good, charged battery is enough for most things.. But you have been warned!
Another option over a ctek is a spare battery connected via jump leads if you have one.

Ah, ok.
Yeah that all makes sense. Hadn't really thought of it like that.
So I can just connect another battery to my battery with my jump leads and it'll do the same job (sort of)?
Might be a cheaper method as all the CTEK's I can find are silly money.
Failing that, would one of these work: https://www.amazon.co.uk/Maypole-MP716-Met...ry+charger1964 SIIA - Gone but not forgotten

The IID itself doesn’t use much power BUT time your self playing for a minute or two with it.... 10-15 minutes with the ignition on uses a lot of battery life. Doing updates take time and a lot of battery. It’s been a while since I did any but normally I’d do a CCF update without connecting any thing. But for the BCM I used jump leads to a running tractor (Ford 7810) and every thing worked fine.

Not sure if the battery jump starters you can get now that pack quite a punch would also do the same as a spare battery and jump leads. May be a worthwhile investment as they are so small they will just tuck into one of the stowage compartments in the boot so you never get caught out with a flat battery miles from home.IID Tool

Just bought a new CTEK from Halfrauds using a trade card which made the price very palatable I am sure it knocked £15 or so off the price.
If you have a card, or know someone who will order it then it is the best price I could find on the internet.

Has my IID for almost 3 years and never hooked the car up to a charger or other running car when using it. I generally make sure the car has been used on a long run, or bung a charger (that doesn’t have supply mode) on it overnight.
Haven’t bricked the car, yet.

Good, but this is exactly what happens, you have got a new tool and understandably want to use it, don’t be greedy and play with it to much in one session or as sure as eggs are eggs you’ll have a flat battery.The maximum a D3 will go with just the engine switched on is 15 minutes, D4 a little longer.
The Iid tool will check the battery voltage before any re-flash is done and if there is insufficient power in it will abort, there is also a permanent voltage display in the top corner of the tool, you’ll still need sufficient power to start the car when you’ve done.
Do not use a battery charger of any type while re-flashing.It can when others can't,
It will when others won't,
It goes where others don't.
