Setup, Compatibility & Care
To ensure optimal performance, verify that the device's battery contacts are clean and free of oxidation before insertion. Always align the positive (+) and negative (-) terminals correctly with the markings inside your device’s compartment. For care, store these batteries in a cool, dry place away from direct sunlight; extreme heat can cause internal chemical degradation and shorten the shelf life. If a device will remain unused for several months, remove the battery to prevent potential terminal corrosion.
