Real-World Testing: Putting Nitecore NL1840HP 4000mAh Rechargeable 18650 Battery to the Test
First Use Experience
I first tested the Nitecore NL1840HP 4000mAh Rechargeable 18650 Battery in my primary tactical flashlight during a week-long backcountry camping trip in the Cascade Mountains. The conditions were varied, ranging from warm sunny days to cold, damp nights, which presented a perfect opportunity to evaluate the battery’s performance under stress.
The NL1840HP performed admirably, providing consistent power to my flashlight even in colder temperatures where other batteries tend to lose capacity.

There was no learning curve; I simply charged it up and dropped it into my flashlight.
Initially, I was surprised by how much longer my flashlight ran on its highest setting without dimming. This indicated the battery was holding a stable voltage output for a significant amount of time.

Compared to my experience with other rechargeable batteries that gradually lose capacity over time, the NL1840HP appears to be retaining its charge capacity exceptionally well.
Compared to the lower-capacity Nitecore batteries I’ve used in the past, the NL1840HP is a significant improvement in terms of runtime and overall reliability. Its performance has exceeded my expectations, making it a worthwhile investment for anyone who depends on high-performance 18650 batteries.
