How to make dry batteries more durable?

Recently, some people often complain that dry batteries are not used. After a long time, the power is gone. Are dry batteries really useless? The following author summarizes four ingenious ways to make your dry battery longer and more durable in combination with the actual life. Method 1: When the flashlight is dimmed, the battery can be installed in an ordinary transistor radio and used for a period of time. The sound of the transistor radio is reduced, and the battery can be used in the transistor alarm clock, and it can run normally for several years. Method two, when you are using an electric shaver or listening to a semiconductor radio, and suddenly the battery power is insufficient, and there is no new battery to replace, you can take out the battery, pinch it hard, and squeeze the outer skin of the battery before reinstalling it. , You can continue to use, this method can be used repeatedly. Method three, when the dry battery is almost out of power, take it out and put it on a radiator to warm it, or put it in the sun for half an hour to one hour. Method four, buy two sets of batteries, mark them, use the first set, and spare the second set. When the first set of batteries consumes 1/3 of the power, replace the second set of batteries, and when the second set of batteries use 1/3, then change back to the first set of batteries, but the two sets of alkaline batteries must not be mixed. Secondly, the unused dry battery can be stored in a plastic bag and put in the refrigerator to prevent it from running slowly and prolong its service life. When the battery in the flashlight is not in use, the next battery can be reversed and placed in the flashlight to slow down the natural discharge of the battery and prolong the battery life. At the same time, it can prevent the battery from being discharged due to forgetting, and the battery will become soft and rust the inside of the flashlight. Cavity.
