Cloud Defensive CD35001 18350 Rechargeable Battery 3.6V 1000-1100 mAh Compatible w/ UI2 Custom Label Charger/D2 Custom Label Charger

The Cloud Defensive CD35001 18350 rechargeable battery is a dedicated power cell designed for Cloud Defensive weapon lights that rely on the UI2 or D2 Custom Label Chargers. If you're running a Cloud Defensive light system and need a proven, compatible battery that matches the protection and charging protocol your light demands, this is the straightforward choice. Built as an unprotected flat-top cell, it integrates seamlessly with Cloud Defensive's ecosystem and the specific chargers rated to work with it.

At 18350 size with a 3.6V nominal voltage, this battery delivers a 1000–1100mAh capacity—enough sustained output for tactical and training use. Its 10A continuous discharge rating suits the high-drain demands of modern weapon-mounted illumination. The flat-top design and unprotected configuration mean this battery must be paired only with compatible chargers and systems that include proper protection circuitry; it is not a universal solution and should not be adapted to other brands or devices.

Like all lithium-ion batteries, this cell requires respectful handling. Store it in its protective case, never loose in a pocket or bag. Charge only on a non-flammable surface using your Cloud Defensive UI2 or D2 charger, and monitor the charge cycle. If the battery emits an unusual smell, feels hot, or appears damaged, stop use immediately. Proper care ensures reliable performance and safety every time you deploy your light.
