I found a new use for my battery monitor 
I installed on each of my two batteries a Bluetooth battery monitor, see my post here.
Yesterday I had to drive to the airport to do an interpreting job for the police, and today i thought: "when did I arrive, and when did I leave?", because usually they do give me a form for my payment, and here they will send it by e-mail. Well, my battery monitor did give me the answer:
As you can see, I arrived a little bit before 15h and left at 16h13!
You can also sometimes use it to check if your repair shop works or not on your car and how long.
