Technical Help! Intelligent Protector for Automobile Battery (Power off protection switch) Kill Switch

[qwerty2018]

I have had problems with my car battery and car is 20 year old Fiat Punto 1.2 and had new Starter Motor and Spark Plugs added early this year plus mechanic says alternator is fine and since late 2019 when car gets cold batteries seems to fail. Friend who is mechanic says add this kill switch as something when car is turned off seems to drain the battery in cold weather. This as soon as the car is switched off is supposed to stop everything including all electricity thus no drain on my battery. I have had another new Varta battery today via warranty and mechanic friends added 'Intelligent Protector for Automobile Battery (Power off protection switch)' as photos will show but the instruction manual is too complicated to understand. It is operated on/off switch via a key fob but I do not know when to turn this new device on and off. It really is getting to me this problem and might be last chance saloon for my car and I will not get another one. Huge thank you for reading this and any help.

If you want to use your car then you must have the remote set to 'on'. But once it is on there is no urgency to turn it off unless you are leaving the car for many hours.

Huge thank you here and a long drive tomorrow for a walk in the countryside so will follow your kind help here but turn it off once I get to my destination as will be gone for several hours but will turn it on again when driving home

Another question is what is the sequence for starting your car - Is it turn key fob on before you get into car then unlock door, sit down in car and start engine or unlock door, get into car sit down and then turn key fob on and then start engine? Huge thanks here

I cannot see any technical reason why it makes a difference.

You have some sort of parasitic drain on the battery which is fairly easy to figure out with a £10 multimeter and a YouTube video, all this does is make the car harder to use, when what it probably needs is a new relay somewhere.

An issue with killing all the power is a loss of the engine ECU self learned engine map which in closed circuit mode will be optimised for the car, if you keep cutting the power you will start to find your fuel use goes up as the ECU will go to a fixed basic engine map each time you turn the power on

Many thanks here and apologies for delay in response. Prior to installation of the Power off protection switch (kill switch) the mechanic friend of mine used a multimeter and tested the ECU in the engine and also under the dashboard on the drivers side and found nothing.
