I have a lexus CT 200H hybrid, I just wanna know if in case i am gonna leave town for few days and my car is left behind, can i remove the terminals of my car's 12V battery to prevent any drainage for the period I am away?

 

A few days should not be an issue. If it is, then your 12 volt battery needs replacing anyway.

Removing the terminals on a modern car will most likely wipe your "settings" which you will have to reprogram? IDK. I wouldn't do it.

 

I would not. I have left it not driven for a month with no issues.

 

Might want to buy a battery tender so you don't have to disconnect it.

 

you are fine if just a couple days. even a couple months is fine. i wouldn't start worrying until you get into the half a year range. then at that point i'd just connect it to one of those plug things to keep it from discharging

 

Thank you all for your help and this would definitely help
