18650 Battery Appraisal

XLY Li-ion 18650 1200mAh 3.7V Rechargeable Battery with Connector

The item is a cylindrical lithium-ion battery, commonly known as an 18650 cell, wrapped in a blue insulating sleeve. Its physical dimensions are consistent with standard 18650 cells, which are approximately 18mm in diameter and 65mm in length. The blue wrapper is smooth and appears to be heat-shrink tubing, providing insulation and containing the battery's branding and specifications. Printed in white on the blue sleeve are the manufacturer's name "XLY", the battery type "Li-ion 18650", its capacity "1200mAh", and electrical specifications "3.7V 4.44Wh". Below these details, a 'CE' marking and what appears to be a 'WEEE' (Waste Electrical and Electronic Equipment) symbol are visible, indicating compliance with European safety and recycling standards. The positive end of the battery, partially visible, has a red wire connected, and the negative end, also partially visible, has a black wire connected. These wires lead to a small, black, rectangular two-pin connector, indicating that this is a 'protected' or 'pre-wired' cell, ready for integration into a device. The insulation around the terminals appears to be intact, and there are no visible signs of swelling, punctures, or leakage, suggesting it is in good physical condition. There are no obvious signs of wear, damage, or repairs. The craftsmanship appears standard for mass-produced electronic components. Given the prevalence of 18650 cells in various electronic devices, this particular cell with pre-attached wires and a connector would likely be intended for specific applications such as power tools, portable lights, or custom battery packs where a direct connection is needed without soldering. The blue color is typical for many battery manufacturers.
