Dry cells are useful because they provide a reliable and portable source of electrical energy for a wide range of devices, from flashlights to remote controls. Their compact design and ability to function in various orientations make them convenient for everyday use. Additionally, dry cells are relatively safe and have a long shelf life, making them ideal for consumer products and emergency kits. Overall, they enhance the accessibility and convenience of portable power.
