18650 Batteries

18650 batteries are rechargeable lithium-ion batteries that have become increasingly popular in recent years. They are named after their dimensions of 18mm by 65mm and are known for their high energy density, which means they can store a significant amount of energy in a small size.

One of the key advantages of 18650 batteries is their ability to be recharged multiple times, making them more eco-friendly and cost-effective in the long run compared to disposable batteries.

However, it’s important to note that not all 18650 batteries are created equal. There are a wide variety of brands and types available on the market, each with their own specific characteristics and performance capabilities. When choosing an 18650 battery, it’s important to do your research and select a reliable and high-quality product that meets your specific needs. At brightnite.com.au we only use the highest quality cells from companies like Sanyo and Panasonic and all our cell are tested and approved for the flashlights we sell.
