What are rechargeable batteries?

Rechargeable batteries, also known as secondary batteries, are batteries that can be charged and used repeatedly. These batteries can be recharged when they have been discharged and then used again, so you don't have to throw them away after a single use.

There are various types of rechargeable batteries, each with different characteristics in terms of capacity, charging time, and lifespan. Rechargeable batteries are suitable for various purposes depending on the requirements of energy storage and needs.

Rechargeable batteries can range from batteries used in computers, mobile phones, cameras, etc., to small AA batteries that you can use in remote controls, battery-powered lamps, and similar devices.

How do rechargeable batteries work?

When we charge a rechargeable battery, electric current is sent through the battery in the opposite direction, causing the chemical reaction inside the battery to be reversed. This leads to the restoration of electrons and the electrolyte to a state where they can generate electricity again.
