Device Identification and General Information
The product in the image is a battery pack used to power electronic devices. The image shows 1 battery pack and connection cables integrated into this pack. There is no brand name or logo on the product.
Physical Condition
The outer surface of the battery is covered with a black protective material. On the black surface beneath the white information label, there are noticeable scratches, scuff marks, and superficial deformations resembling adhesive residue. The overall appearance of the product indicates that it has been used. The word Sağlam (meaning ‘Sound’ or ‘Intact’) is handwritten in blue ballpoint pen at two different points on the label.
Cables and Connection Assembly
A total of five connection cables, colored yellow, green, white, black, and red, emerge from the bottom of the battery. The ends of these cables terminate in a black connection socket, and the base of the socket is wrapped with black tape or heat shrink tubing. In the middle section of the red cable, a distinct repair, insulation, or splice point made with red tape or heat shrink tubing is visible.

The label contains safety instructions under the English heading CAUTION!, including warnings about flammable and explosive materials, not short-circuiting, not disassembling, and charging only with an appropriate charger. Additionally, a recycling symbol and a crossed-out trash can symbol, indicating that the product should not be disposed of in general waste, are present on the label.
Potential Failure Risk
The insulation or splice point observed on the red cable, which appears to have been added later, may create a risk of intermittent contact or breakage if the cable is stretched or bent. Scratches and wear on the outer casing are superficial defects. No swelling, leakage, or chemical spillage was observed on the battery through the visual inspection.
