I recently purchased the UltraFire 3000mAh 3.7V 18650 Rechargeable Lithium Batteries without Protection Board (2PCS) as a replacement for the counterfeit batteries I had previously bought. I must say, the difference is like night and day.these batteries are genuine and reliable. The previous counterfeit batteries I had purchased not only performed poorly but also caused my flashlight to malfunction, which was a major disappointment. However, with these UltraFire batteries, I have not encountered any issues so far. The flashlight now functions flawlessly, providing a bright and consistent beam of light.
The battery life of these UltraFire batteries is also commendable. With a capacity of 3000mAh, they last significantly longer compared to the counterfeit batteries I had used before. This means that I can use my flashlight for extended periods without worrying about the batteries dying on me.

Thank you for your kind words and support! We truly appreciate your positive feedback on our UltraFire brand. We are committed to delivering
