18500 Batteries

An 18500 battery is a rechargeable Lithium Ion or LiFeP04 battery that is commonly used in electronic devices that require a high level of power output and extended run times, such as solar lights, flashlights, and other high-drain devices. 

The 18500 battery measures 18mm in diameter and 50mm in length, making it a little shorter than the 18650 battery. The 18500 battery typically has a voltage of 3.7 volts and a capacity of between 1400 and 2000 mAh, which is higher than that of a standard AA battery. One of the key advantages of the 18500 battery is its rechargeability. It can be recharged multiple times, either in the electronic device or using a battery charger.

The 18500 battery also offers high energy density, which means that it can store a relatively large amount of energy in a compact size. This makes it an ideal choice for portable devices where space is at a premium.

The 18500 battery has a high discharge rate, which allows it to deliver a large amount of power quickly. This makes it suitable for high-drain applications that require a lot of power, such as flashlights and power tools.
