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

didn't last a year! I paid the same price for this battery as the flashlight that came with the battery (4400mAh). Light and battery work. I bought it 13 months ago hopefully to last longer. When it worked it could last longer between charges, in July I had an accident so I didn't ride the bike for four months (which means I used it for about 8-9 months) and tried it charge. It doesn't charge at all. I think the battery should last longer. So a bit disappointed. Update 12/30/17 - Changed from 3 stars to 4 stars. Because I should have contacted customer service sooner as they replaced it quickly. The insights gained give customer service the opportunity to do things right.
