A battery hack for anyone and it’s so simple that you’ll be glad you read this.
Let’s say you need a double A (AA) battery and you don’t have time to run to the store… because it’s right in the middle of your child’s birthday party, or you need to take Fido out for a walk ASAP and it’s dark outside and the flashlight is dead. If you have a triple A (AAA) battery on hand, you can use that. Just fold up a small piece of aluminum foil and put it on the “+” side of the battery. The foil will act as a conduit and give you enough power to get through the energy crisis of the moment.
