How to Make Dying Batteries Work
Batteries are essentially energy holders. They contain a certain type of acid that holds the protons and electrons stable until a point of discharge is provided. Connecting a positive lead to the positive on the battery, and connecting a negative lead on the negative side of the battery, allows the stored energy to be discharged from the stabilizing acid and power your component. Here's how to get extra life out of your battery.
Place low batteries on top of your gas or electric stove (never inside the oven). Set your oven to 350 degrees F. It is most convenient when you are already cooking something so as not to waste energy.
Let batteries sit on the stove for about an hour. The heat from the stove causes the electrons and protons to become "excited," giving off more energy for a short time until the battery assumes room temperature and the electrons and protons slow down to their static states. This technique give you about 30 to 60 minutes of renewed battery life before reaching room temperature again and being completely used up.
Freeze old batteries, as a second option. Take the batteries you want to charge and put them in the freezer (not in the refrigerator, as there is not enough temperature difference).
Allow the batteries to cool about 30 minutes and remove from freezer. As the batteries rise in temperature, the electrons and protons inside are "excited" and create more battery life for a short time. Once the batteries completely come to room temperature, all energy will be gone and the battery will be completely dead.
Tips & Warnings
- Use potholders to remove batteries from stove top. They are not usually very hot but it is a good precaution.
- Do not put batteries in the oven, microwave or any direct heat source. The batteries will explode and you could be burned by the acid inside.
