There was a time when there was no concept of being able to move electronic devices from one place to another. However, ever since the introduction of batteries, the portability of many devices has increased to a greater extent. Take the example of telecommunications. With the introduction of cell phones and their increased portability, communication has become so much easier. And to a greater extent, that evolution has been accredited to the fact that cell phones come with a rechargeable battery that makes their portability much easier. With batteries becoming rechargeable and smaller, the devices have become easier to carry and maneuver.
When it comes to rechargeable batteries, there are a few types that are available to people. Among these, the most in-demand batteries are Lithium-ion or Li-ion batteries and the alkaline batteries. Since the two have been in equal demand on sites such as amazon.com where many of their brands are on the bestsellers’ list, it is imperative to know how they differ from each other. Moreover, it will also help in determining which one is better than the other.
