What is the difference between alkaline and lithium batteries?

The main difference between alkaline batteries and lithium batteries is performance and lifespan. Lithium batteries last longer, provide higher energy density, and work better in extreme temperatures, while alkaline batteries are more affordable and ideal for everyday low to medium power devices.

Alkaline batteries are the regular ones you find everywhere, cheap and great for low-drain devices like remotes or clocks. Lithium batteries are more expensive, but they last much longer, perform better in high-drain devices like cameras, and handle extreme temperatures without losing charge as fast.
