Toys, electronics, kitchen appliances, health and beauty devices and so many other items in your home require batteries that it makes sense to buy in bulk and have a variety on hand. But if you don’t know how to store batteries properly, it can mean wasted money.

How To Store Batteries For A Longer Shelf Life

Although countless people have been taught to do so, keeping them in the refrigerator is not how to store batteries. That’s because of the condensation that builds up inside, which can damage batteries. Experts advise that batteries last longest when stored properly in a dry, room-temperature setting.

Panasonic recommends leaving new batteries in their original packaging until you need to open them. Doing so protects batteries from environmental factors that might affect their power, such as humidity. Plus, if the terminals of loose batteries make contact, they can short-circuit.

Once opened, the best way to store batteries may be in an organizer designed to keep them stable, prevent them from touching and protect them from the elements. Most organizers can contain and preserve a wide variety of battery types. Some are portable, and others can be mounted on a wall for quick access. Many also come with a battery tester, which reduces the challenge of finding a good battery fast.

Following are our top picks for the best battery organizers.
