Cloud Defensive 3.6 V Replacement 18350 Lithium-Ion Battery

This is an unprotected, flat-top cell, which is important to note for compatibility with certain weapon lights. Many common brand weapon lights are not rated for unprotected cells like this one, so caution is necessary. To charge this specific battery, use the UI2 Custom Label Charger or the D2 Custom Label Charger, both of which are designed for this type of cell.
