Review on 🚴 The Best Bike Light Battery with Higher Capacity for Bright Eyes CREE T6 LED 1200lm Bike Lights - 8.4v Power Upgrade by Richard Cartner

I had an old battery that wouldn't even give me an hour of full power on my headlight, maybe 2 hours on low before it died. After charging these I used my flashlight for 3-4 hours on 3 different trips, on low with lots of use on high before deciding to charge it. It wasn't even empty when I loaded it. I'm amazed at how long it lasts with my light compared to my old batteries. It really adds a lot of intelligence and ensures your lightweight battery doesn't die in the middle of a ride. Update 11/28/16 The connector no longer connects to the charger or flashlight. I'm 99% sure it has enough charge. I think something in the keg plug has somehow come loose. I will contact the seller. The seller offered me a nimble battery to replace the defective one. Update: 10/08/17 And so it happened again. This time I drove at night when my lights went out. I unplugged and plugged it back in, moved the cords around a bit and was able to turn the light on by moving the wire and plug a little and I managed to literally come home with a band-aid to shut it off try and keep it so that it stays. It turned off as I pulled into the driveway. The cells in it are still very, very good, but they can't connect. They seem to last about a year/a few thousand miles before the wire going into the barrel connector seems to come loose. somehow despite my best efforts to ensure the ports are not loaded. This has happened twice already and I get a battery case to put the batteries in instead of getting another replacement if they can't offer a free one.
