This high-quality 18650 battery is the official replacement for the RGB Critter Flashlight. Designed to fit perfectly within the Critter's compact body, we recommend using only this battery for proper performance and safety.

Recharge the RGB Critter with the included USB-C cable, or swap the battery when needed. For a quick guide, see the RGB Critter BT charging instructions video, and review our battery handling tips for the best life and performance.

Please note

  • Due to shipping regulations, we cannot ship standalone batteries to international addresses or via overnight methods.
  • Battery appearance may vary from the photo. We no longer use the custom AOAM wrap, but this is the same approved 18650 replacement battery for the RGB Critter Flashlight.
