As a battery enthusiast, it&#;s important to understand the basics of batteries before diving into the details. In this section, we&#;ll cover everything you need to know about batteries, from their basic definition to their compatibility with devices.

What are batteries?

batteries are cylindrical lithium-ion batteries that are 21mm in diameter and 70mm in length. They are larger than the popular batteries and have gained popularity due to their high energy density, longer run time, and increased safety.

Capacity and dimensions

The capacity of a battery can vary depending on the brand and model, but they typically range from mAh to mAh. This high capacity, combined with the larger size, makes the battery an excellent choice for devices that require a lot of power. Currently, the highest capacity of battery is mAh at the market.

Unprotected and protected types

Like other lithium-ion batteries, batteries come in both protected and unprotected versions. Unprotected batteries are simply the bare cells without any additional protection, while protected batteries have a built-in protection circuit that helps to prevent overcharging, over-discharging, and short circuits.

It&#;s important to note that unprotected batteries can be dangerous if not handled properly, so it&#;s recommended to use protected batteries in most devices. However, unprotected batteries can be useful in certain applications where maximum power output is needed.

Compatibility with devices

Many high-end devices, such as flashlights and vaping devices, are designed specifically for batteries. However, some devices may also be compatible with or other battery types. In addition, Not all batteries are created equal. Some devices may only work with certain brands or types. So be sure to check your device&#;s specifications before making a purchase.

With these basic concepts in mind, let&#;s dive deeper into the world of batteries and explore their benefits, top brands, and more.
