It holds more power so I charge it less. Only real improvement I can see would be to include a push button meter like drills all have now. This has a hard shell vs the original that had a rubber surround but it also is shaped so it can strap to the bike well. My only worry is that it might crack or something if it’s dropped or somehow were to fall off the bike which isn’t very likely. It’s a little bigger in size compared to original battery as well. When I use the light as a headlamp instead of on the bike I just Velcro the straps around my belt and it works well enough for me. Makes for a nice light for long hikes, the run time outweighs the weight of the light for me as I need no extra batteries.One note but might be perceived and not real: seems to hold charge best when you keep the light unplugged when not in use.Recommend for anyone who has the original battery, plus having two batteries means it’s never an issue on longer rides. Keeps you good and visible at night. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Good πŸ‘ *by M***N on Reviewed in the United States on January 15, 2023* By this one ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works Great! *by A***N on Reviewed in the United States on December 31, 2022* I had the original bright eyes lights five years ago or more. Had to get different lights because the battery would not run for two hours. This new bigger battery has yet to even run low after two hours. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/196843494-10-400mah-waterproof-bike-light-battery-now-higher-capacity-works](https://www.desertcart.hr/products/196843494-10-400mah-waterproof-bike-light-battery-now-higher-capacity-works) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
