Frequently asked questions

Have questions? We’re here to help

Title

Q1: ​​​​Can I use standard CR123A batteries in a 16340 flashlight?​​

A: Yes. UltraFire flashlights support ​​both 16340 rechargeable and CR123A disposable batteries​​. However, CR123A provides lower brightness (e.g., 400 lumens vs. 700 lumens with 16340) but excels in extreme cold conditions.

Q2: ​​​​How do I prevent overheating during prolonged use?​​

A: Limit high-brightness modes to 30-minute intervals.
