This is the best tip we have seen in a long time! If you run out of AA batteries but have some AAAs laying around and some tinfoil you’re in luck.
Wrap up a ball of foil and stuff it into the case of your device where the battery’s positive terminal connects (we read you can do it both ways, but we only tried positive.) As long as you have enough foil to fill in the gap and make it tight, it should work.
This of course isn’t a permanent fix but should get you through until you can get to the store.
