Sony was the first to mass-produce and sell lithium-ion batteries. Since then, improvements and tweaks have been made to increase the battery's output and longevity. These improvements resulted in a more reliable battery, which in turn led to higher market demand and increased use. 

Today, lithium-ion batteries are the dominant type of battery in the industry. You can also buy a 18650 lithium-ion cell for your laptop via web search.

An 18650 battery is a battery made of lithium-ion. The battery's exact measurements are 18mm x 65mm. This is how the name came about. This battery is slightly larger than an ordinary AA battery. 

These batteries are often used in flashlights and laptops as well as electronics and electric cars due to their reliability and long life spans. They can also be recharged hundreds of thousands of times. 18650 batteries are what you would call a "high-drain battery."

These tiny batteries are used in power-hungry, more complicated electronics that require constant power. The battery also has a high level of discharge. This means that it can be completely drained down to 0% without affecting its ability to recharge fully. 

This is not a good idea as it can cause damage to the battery over time and reduce its performance. This article will provide more information about how to prolong the battery's life and care for it.
