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.
