Real-World Testing: Putting USED SureFire SF18350 Surefire Micro USB Lithium – 1 out of 3 models to the Test

First Use Experience

I first tested the USED SureFire SF18350 in my SureFire EDCL1-T during a weekend camping trip in the local mountains. The goal was to assess its runtime and charging capabilities under real-world conditions.

The weather was mild, but the nights were dark, providing ample opportunity to evaluate the battery’s performance. I found the charging process very simple using a portable power bank.

After the first night of use, the battery showed a noticeable decrease in brightness towards the end of its runtime, as expected with lithium-ion batteries. It did prove reliable for several hours. There were no apparent issues, although a small amount of the original runtime has probably diminished.

Extended Use & Reliability

Over the past three months, I’ve consistently used the USED SureFire SF18350 in my daily routine, recharging it via USB as needed. The battery continues to provide sufficient power for my typical daily requirements.

So far, the battery has exhibited no significant degradation in performance, though lithium-ion batteries do degrade over time. Minimal additional wear and tear have been seen.

Maintenance involves nothing more than occasionally wiping down the battery with a dry cloth. Considering this is a used battery, it has exceeded my expectations, and has proved to be more convenient than purchasing standard disposable CR123A batteries.
