HydraCell HC1D Power Cell for AquaTac Flashlight (2021 Model)

The HC1D water-activated energy cell is the eco-friendly power source for the AquaTac flashlight.
Before first use, the cells can be stored in their original heat-sealed packaging for over 25 years.

Activating it is very simple: Just submerge it in water for 10–15 seconds —after that, the energy cell is immediately ready for use and provides over 60 hours of power, provided it is reactivated occasionally.

The HydraCell significantly reduces the use of disposable batteries, making it a sustainable alternative—it is biodegradable, non-toxic, and safe.
