How to Store Batteries for Emergencies

When the power goes out, it is important to know where some extra batteries are in case the ones in your flashlight are dead. Batteries can also be used for other devices that may be useful in an emergency, such as portable radios. Storing batteries takes some thought, but it can be really convenient when they are needed most.

• Make sure that the place where you are putting the batteries is dry and isn’t too hot. The temperature should be about 70 degrees Fahrenheit and the area should be free of condensation to prevent battery damage.


• Put the batteries in an area that you are usually close to. If the lights go out, you don’t want to have to travel across the house without any light source. Try keeping the batteries in the familiar place next to a flashlight.


• Take the batteries out of battery-operated devices when you’re not operating them. Even though the device isn’t on, it can still affect battery power.


• Use batteries that have an equal amount of life. If you use a fully-charged battery with one that is almost dead, the power of the good battery will drain much faster. You can keep equally charged batteries together by placing them in the same zip lock bag when they are not in use.


• Do not charge batteries for more than 12 hours. Overcharging batteries reduces their lifespan. Many chargers have indicators on them that will tell you when the battery is fully charged. If the charger says the batteries have a full charge, remove them and store them in a place that dry and away from excessive heat.
