Battery FAQs

Are protected batteries safer?
Protected cells include a built-in circuit that helps prevent over-charge, over-discharge, and short circuits. They’re often recommended for general use but may not fit all devices.

Can I use USB-C rechargeable batteries in any flashlight?
Only if the flashlight supports the battery’s length and output. Always verify compatibility before use.

Do all flashlights use the same battery type?
No. Battery size, top style, and protection requirements vary by model. Always check the flashlight manufacturer’s specifications.
