Alkaline batteries are the most commonly used battery to power modern devices such as flash lights, digital cameras, remote controls, toys, clocks, and alarms. These industrial batteries are designed for long-life and reliability. They work in both cold and hot temperatures, making them a reliable, long-lasting source of power. Alkaline batteries have a 5 - 7 year shelf life when stored at room temperature, so you can feel free to have a couple more packs on hand as needed.
