How is Different from Other Batteries?

A lithium battery is different among any other batteries because of its performance. This type of battery contains more power and has efficient rechargeable features. This is because of its lithium and carbon content.

The lithium is a highly reactive element. Hence, it can store more energy in its molecular bonds.

Let’s get that into perspective.

A 1-kilogram lithium-ion battery can deliver 150 watts of electricity while a Nickel-Metal Hydride (NiMH) of the same size can only deliver 60 – 70 watts.

Also, a lithium battery is relatively lighter than other types of power cells.

Are There Any Downsides to Lithium Batteries?

Although lithium batteries are efficient power sources, they have some disadvantages that you should watch out. One of these is that this battery is very sensitive to high temperatures. Another one is that it can be ruined if you completely discharge it.
