Holding power for up to 10 years while in storage, the well-built battery’s air- and liquid-tight seal securely contains the power until it’s needed. The battery locks in power and won’t leak thanks to its improved anti-corrosion components, new zinc composition, and two-crimp design. A great choice when buying in bulk, the long-lasting AmazonBasics batteries can be used immediately or stored for reliable power later—perfect for weather radios, flashlights, and other must-haves in an emergency.
