Extend Battery Life
Dealing with dead batteries is always an inconvenience, as you never know when they are going to die. There is no way to make your batteries last forever, but there is a way to help extend the life of your batteries. All you need is a little bit of aluminum foil to make your batteries last longer.
Add a little piece of aluminum foil to the positive ends of both the battery and the device. The aluminum foil will allow all the power from the battery to be drained. This is a simple method that will save you time and money in the long run.
