Here is a headlamp system (battery + headband) which I gladly purchased (twice now) to outfit two, HC65 UHE headlamps I bought earlier. One headlamp is my back-up... as some of us search-and-rescue folks tend to like reliable gear (in pairs). I don't have a longevity review yet... But I will add that extra bit of information as more time passes and I've used the system under a variety of situations. I can say though, after at least 2-months of regular use (both short and extended) that I like it. The standard set up for the HC65 UHE is great. No complaints. Battery life is wonderful (providing bright, adjustable light and reliability). But just knowing that I'm drawing from the extra battery on the backside of this kit (FIRST) gives me great piece-of-mind when I'm out at night and need to illuminate an area hands-free... while on extended walks or runs. Having a fresh, primary battery inside the light itself just feels right. I've used this extra battery system in rainy, chilly autumn downpours and I'm still grinning ear-to-ear at the value this system provides me (and my dog) as we're out and about in unlit (and occasionally sketchy) areas. The connectors are solid. I've not had any issues with them coming loose at all, whether I've tossed this system in a tightly-compressed dry bag or a loose bag with other items bouncing around with it. The simple headband adjustability, forehead slipstrip and general headband aesthetic remain (as it should). The battery itself is very long lasting (more info to come there with longevity testing). I do love the red charging indicator (4 leds) that give you feedback on the staus of your charge. This doubles as a rear, blinking, caution light (or guide light if you're in a group)... Or you can opt out of that feature entirely and turn that part off. Nice. Nitecore, have you done it again? At least for THIS guy you have. Yes, you have. Thank you! Review: Best headlamp i have ever found - I've owned several headlamps and this is finally the best i have found. The battery life is great and it will stay on the high mode and not fade out after time. It's got good range and we love it for razor clam digging. Definitely work the money and buy the extra battery pack. ## Features - DOUBLES OR TRIPLES RUNTIME - When connected to the headlamp, the Nitecore Carbon 6K Kit significantly extends the run time of Nitecore Headlamps such as NU43, NU45, HC60 UHE, HC65 UHE and HC70 UHE Headlamps. - SECURE CONNECTION - Comes with a quick-release cable, reliably connecting the kit and headlamp, and clips to tuck the cable neatly around the headband. - LIGHTWEIGHT - Weighing just over three ounces, carbon 6K fits easily on the back of the headband for a balanced weight distribution and comfortable wearing experience - RED SAFETY LIGHT - A rear red light serves as a signal light at night, perfect for night runners or outdoor workers - CONTENTS - Carbon Battery 6K, Headband, Bracket, USB-C to USB-C charging cable, Nitecore Sticker ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D1HDS2K8 | | Additional Features | Adjustable Strap, Lightweight | | Battery Description | Lithium-Ion Polymer | | Battery Type | Lithium Polymer | | Best Sellers Rank | #133,833 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #510 in Camping Headlamps | | Brand Name | Nitecore | | Color | Black | | Customer Reviews | 4.3 out of 5 stars 50 Reviews | | Finish Types | Polished | | Included Components | Battery, Charging Cable, Clip, Head Band | | Item Dimensions D x W x H | 0.9"D x 3.54"W x 0.9"H | | Item Dimensions L x W x H | 3.54"L x 0.9"W x 0.9"H | | Item Type Name | headlamp runtime extender | | Item Weight | 3.52 ounces | | Light Output Maximum | 2000 lumens | | Light Source Special Features | Doubling or tripling the runtime, rear red light for safety, USB-C port for easy connection and charging | | Light Source Type | LED | | Manufacturer | Sysmax Innovations Co. | | Manufacturer Part Number | Carbon Battery 6K | | Manufacturer Warranty Description | 18 month manufacturer warranty post purchase date. | | Material | Carbon Fiber | | Material Type | Carbon Fiber | | Model Number | Carbon Battery 6K | | Mounting Type | Head Mount | | Number of Batteries | 1 Lithium Ion batteries required.

The battery life is great and it will stay on the high mode and not fade out after time. It's got good range and we love it for razor clam digging.

Absolutely amazing *by T***J on August 9, 2025* I was going to get a HC75 3000lm, but after using this, my HC60 1600lm operates completely different now. Excellent quality, comfortable, pretty lightweight, it operates of the battery first when plugged into the headlamp and is charging the headlamp battery. Completely different light management, so bright , I'm in no hurry for the other one with adjustable flood and spot, nice carbon battery design and charges on a C cable. ## Frequently Bought Together - Nitecore Carbon Battery 6K Kit Headlamp Runtime Extender for NU40, NU43, NU45, NU50, and HC65 UHE Headlamps - Nitecore NU53 1800 Lumen Headlamp, USB-C Fast Charging Long Runtime Lightweight Designed for Industrial uses with Auxilary White and Red Light Sticker - Nitecore NU43 Rechargeable Headlamp, 1400 lumens USB-C Bright Lightweight for Camping, Running, or Working, with Spotlight, Floodlight, Red Light, Including NitecoreS Sticker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/632699804-nitecore-carbon-battery-6k-kit-headlamp-runtime-extender-for-nu40](https://www.desertcart.com.sa/products/632699804-nitecore-carbon-battery-6k-kit-headlamp-runtime-extender-for-nu40) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-08-10*
