Lithium Ion Battery (Stylus Pro USB/COB) Review

First Thoughts on the Lithium Ion Battery (Stylus Pro USB/COB)

The Lithium Ion Battery (Stylus Pro USB/COB) from Streamlight might seem like a small, unassuming piece of kit, but it’s a crucial component for those who rely on their flashlights in demanding situations. The Stylus Pro line has always been about compact power, and a reliable battery is fundamental to that. What initially caught my attention was the promise of rechargeable convenience, moving away from disposable batteries for my everyday carry light.

For years, I’ve been using various tactical pens with integrated lights, and the common weak point is always battery life. I needed a consistent, reliable power source that could be easily recharged, eliminating the constant need to buy and carry spare alkaline batteries. My old Streamlight (similar model) kept dying at the most inconvenient times, which is why I was looking for something with better power management.

Upon receiving the Lithium Ion Battery (Stylus Pro USB/COB), the first thing I noticed was its robust construction and how it felt immediately more substantial than standard AAA batteries. The packaging was simple but effective, protecting the battery during shipping. Compared to using standard alkaline batteries or even some generic rechargeable options, this felt like a step up in terms of quality and purpose-built design. I considered Eneloop rechargeables, but those would have been a downgrade from the batteries included with my Stylus Pro.

My initial impression was positive. I was excited to test its runtime and charging capabilities in real-world scenarios. This battery promised a solution to my biggest gripe with EDC flashlights.

Real-World Testing: Putting Lithium Ion Battery (Stylus Pro USB/COB) to the Test

First Use Experience

My first real test of the Lithium Ion Battery (Stylus Pro USB/COB) came during a nighttime search and rescue training exercise with my local volunteer team. This involved navigating through dense woodland in near-total darkness. The battery was powering my Stylus Pro USB, which I used for close-range illumination while tracking.

The battery performed flawlessly throughout the initial four-hour exercise. The light output remained consistent, and there was no noticeable dimming, even as the hours passed. The wet, damp conditions of the forest didn’t seem to affect its performance at all. It was significantly easier to manage power compared to using the disposable alkaline batteries that drain quickly under heavy load.

Extended Use & Reliability

After several weeks of using the Lithium Ion Battery (Stylus Pro USB/COB) daily, I can confidently say it holds up well. I used the Stylus Pro, powered by this battery, during a week-long camping trip, performing tasks like setting up camp, navigating trails at night, and general illumination around the campsite. There are no visible signs of wear and tear on the battery itself.

Maintenance is incredibly simple – just plug the Stylus Pro into a USB port to recharge. It is far easier than dealing with replacing or charging multiple alkaline cells. Compared to my previous experiences with disposable batteries, this Lithium Ion Battery (Stylus Pro USB/COB) is a massive improvement in terms of reliability and convenience. It consistently outperforms standard batteries.
