Model 3

Because I am not that wise on batteries, energy, etc...

In my M3 I keep a small flashlight which is charged by way of a USB cable.

I charge the light at home, place it in the glove compartment where it lays in case of an emergency. But every 6 months or so, it has to be recharged.

Because I am not that wise on batteries, energy, etc...

If I were to keep it always plugged into the car and I do not drive the that car that much, could that create a battery drain or would it be so small as not to worry about it?

  • Zero worries though it might weaken the battery in the flashlight.
  • That is what I hoped.

    Flashlight, I don't worry about. Car battery I do.

    Thanks
  • I agree with Bighorn.

    I solved the problem by buying a non-rechargeable AA LED flashlight, and using Energizer Lithium AA batteries. They have a long, long lifetime when sitting, so I figure the likelihood that it'll work when I need it is a lot higher than a rechargeable that I have to remember to recharge, or a rechargeable left plugged in all the time where an electronics failure could occur.
  • USB charging only works while the car is on. :)

    That's even better. Won't drain while sitting for a few days but will charge when driving.
  • The car battery charge could probably last your entire lifetime recharging a flashlight were that the only draw.
