My boyfriend was given a cheap flashlight/jump pack by a friend. When you open the battery cover, it takes an 18650. Normally the flashlight would last about 3 hours on a full charge (1 LED). It was left in the pocket of his pants and made a trip through the washer. When he went to swap clothes in the dryer he noticed it because the flashlight was on. He then put it aside leaving the light on. Since then, we have not plugged it in or really messed with it at all. It has now been going for 6 days!! How is this possible?? Its the ongoing joke here that he has accidentally created a never ending battery. I should note that the insulator ring started peeling off. Any ideas on how this is even possible???
