Battery Functions and Types
A battery is a device that can convert stored chemical energy into electrical energy that can be used by an electronic device. Almost all portable electronic devices such as cellphones, laptops, flashlights, or remote controls use batteries as their power source.
With the battery, we don't need to connect an electric cable to be able to activate our electronic devices so that they can be easily carried everywhere. In our daily life, we can find two types of batteries, namely batteries that can only be used once and batteries that can be recharged.
