The STINGRAY MARK II LED torch is powered by a 21700 Li-Ion battery that provides a long runtime (about 2 hours) and is characterized by an extended lifespan (up to 500 charging cycles with up to 75% capacity) as well as a high level of safety.

Thanks to the built-in PCM, the battery is protected against overcharging, over-discharge, and short-circuiting.

Please note that despite having the same name, 21700 Li-Ion batteries from other manufacturers may differ in diameter and length, making them incompatible with the LED STINGRAY MARK II. To ensure optimal performance and reliability, we recommend using batteries marked by Ammonite System.
