What is the difference between alkaline and lithium batteries?

Alkaline and lithium batteries vary in terms of chemistry, performance, and applications. Alkaline batteries are made of a zinc manganese dioxide chemistry, whereas lithium batteries use a lithium chemistry. Lithium batteries offer higher energy density and longer shelf life, making them ideal for power-hungry devices like digital cameras and electronics. They also have better performance in extreme temperatures. Alkaline batteries, on the other hand, are more readily available and cheaper. They have a slightly lower energy density, making them better suited for low-drain devices such as remote controls and clocks. While alkaline batteries are disposable, lithium batteries often come in rechargeable options, allowing for multiple uses. The choice between alkaline and lithium batteries largely depends on the device's power requirements and intended use.
