Review on 🔦 Waterproof Headlight for Outdoor Sports - SecurityIng 1800Lm 4 Modes 3 LEDs Headlamp & Bicycle Light with 4400mAh Battery Pack and Charger by Melvin Belton

Although I have owned this flashlight since December 2014, I used it for the first time today. Charged all night, and this morning I went for a walk. I put the light on "strobe" and the battery only lasted 30 minutes. I read that the battery lasts 2 hours on "High". I am extremely disappointed. I took the battery to my local Batteries Plus store to have the battery checked and sent a contact message to security. I have not received a response from the manufacturer and Batteries Plus will call me tomorrow morning. Before the battery died, I was very impressed with the light. It is to be hoped that the manufacturer will honor its guarantee. Update: The seller sent a replacement battery which is of much better quality. I also bought an 8800mAh battery from Stuppybright.com which lasts for 2 weeks of travelling. A problem I didn't expect. When the display is in the flashing mode, it interferes with the operation of the wireless cycle computer. Trying different positions of the light and the computer, I found a place where the computer is happy, but if either of them move, the computer either goes crazy or stops working.
