Lasts a very long time. Bought another for my GF’s bike and we used them several times a week on our late afternoon trips in town. Review: High capacity; solid plastic case; mounts securely: Be sure to get the optional charger - My old battery was no longer holding a charge, and occasionally I was worried about running out of power, so I upgraded to the larger one. I'm so glad I spent a little extra to get a spare charger, as it turns out my old battery was fine, but the charger was the problem. I had been thinking it would be nice to have one in my bike bag and one at home. I love the solid plastic case; it looks very weatherproof. The velcro straps keep it very secure. On my bike, I only use one of the two straps where it's mounted, and it's still solid. I would love if they would toss in an an extension cable to allow for mounting farther away, but the built-in cable is fine for most uses. ## Features - Bright Eyes 10,400mAh Bike Light Battery: Ultra capacity for enduring long rides with enduring bright lights. - Upgrade Your Battery: Replaces Bright Eyes Stamina battery, Upgrades Helios, and Blaze models for longer runtime. - Versatile: Also compatible with most similar 8.4v external battery bike lights - Proudly USA-Based: Unlike our competition, we are proud to be a USA-based company, committed to delivering quality and reliable products while providing excellent support to our customers across the nation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083XM88WR | | Auto Part Position | Rear | | Best Sellers Rank | #200,822 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #367 in Bike Lighting Parts & Accessories | | Brand | Bright Eyes | | Brand Name | Bright Eyes | | Color | 10,400mAh BATTERY + CHARGER | | Customer Reviews | 4.2 out of 5 stars 54 Reviews | | International Protection Rating | IP65 | | Light Output Maximum | 1800 Lumens | | Manufacturer | Bright Eyes | | Manufacturer Part Number | 6123019 | | Material | Plastic | | Material Type | Plastic | | Mounting Type | Handlebar Mount | | Number of settings | 2 | | Power Source | Battery Powered | | Unit Count | 1.0 Count | | Water Resistance Level | Waterproof | ## Images ![10,400mAh Waterproof Bike Light Battery - Now Higher Capacity - Works with Most CREE 8.4v LED Bike Lights, and All Our 8.4v Lights (Blaze, Helios and Stamina Models) - Image 1](https://m.media-amazon.com/images/I/41qCxXsOm-L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice quality and lasts a long time. *by V***R on December 31, 2025* Really good battery for my mountain bike!
