Editor's Pick: For devices like smoke detectors, wireless mice, and game controllers that need frequent battery changes and are a hassle to constantly restock, these lithium batteries last a long time. They handle both low and high temperatures, so you don't have to worry much about weather affecting devices in the garage or outdoors. They can be stored for over a decade without leaking, so keeping a pack in a drawer for emergencies is a solid move.
