Batteries. (Batteries Are Sold Individually)Ultrafire BRC 18650 3000mAh 3.7v Protected Rechargeable Lithium-Ion Battery
Protected 18650 3000mAh rechargeable 3.7 volt battery - charge with the Ultrafire Multi-Battery charger.
The advantage of this cell is that it features a button top making it particularly compatible with many flashlight applications.
Rechargeable Lithium batteries are rapidly becoming a very economical way to lower the operating costs of Lithium-Powered flashlights. We offer a number of different options in order to meet any rechargeable needs. These are Protected batteries.
These fully protected cells simplify usage with their integrated PCB. Perfect for your single cell application these cells are not for pack building as doing so will defeat the PCB protection which is matched to the correct voltage on a single cell. If you are building a pack please choose one of our other cells and the appropriate PCB.

WARNING: Use caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries and chargers. We only recommend using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc., use of lithium ion batteries without a protection circuit is potentially hazardousMore Information:
Ultrafire 18650 3000mAh button top protected rechargeable lithium ion batteries are ideal for use in flashlights because of the button top design. These batteries will also provide many more life cycles than traditional alkaline batteries. Since these are PCB protected batteries, they are best used in single cell applications. If you attempt to use these cells in pack building, the built-in protections are nullified because they have been designed to match the correct voltage of a single cell, which in this case is 3.7V. Note that the image accompanying these batteries shows two cells; the batteries are sold individually.
