Flashlights, cameras, and other electronics eat up batteries, meaning spares are always a good idea. Batteries do not play nice with water, so why not protect them in a durable, waterproof, and convenient capsule?

The Talos capsule is sized to fit lithium batteries, particularly CR123 or 16340/RCR123 sizes.  The capsule interior is made slightly oversized to accommodate larger batteries that are not exactly 16mm x 34mm.  To avoid rattling issues, foam pads are on the top and bottom of the capsule to hold the batteries in place and prevent the batteries from making contact with the aluminum of the capsule.  The entire capsule is also anodized with type III hard anodizing to both prevent scratches and damage as well as add a layer of redundancy with making contact.

Please note that these are SECONDS from our manufacturer. The o-ring groove was not machined correctly and screwing and unscrewing the cap can damage the o-ring after repeated use. Other than that, they have excellent machining, square threads, and come with the optional extender that allows either one 18650 or two CR123s to fit.


  • Sized to hold and protect one CR123/16340 battery.
  • Foam pads on top and bottom of the interior of the capsule to hold battery in place and prevent contact.
  • Square threads for improved seal and wear resistance.
  • O-ring sealed for a watertight seal (read note above).
  • Oversized lanyard attachment point to fit large keyrings, paracord, or other attachment methods.


  • Exterior dimensions without extender:  51mm (height) x 24mm (diameter)
  • Exterior dimensions with extender:  51mm (height) x 24mm (diameter)
  • Interior dimensions without extender:  35.5mm x 18.77 mm (diameter)
