Shearwater Research REPLACEMENT Battery Cap - Perdix

The Shearwater Research Perdix Battery Compartment Cap fits ONLY the Perdix dive computers It does NOT work with Predator, Petrel 1, or Petrel 2 computers. Just to be clear, if you use this cap on anything other than a Perdix, your dive computer will flood and it will not be covered by any warranty.

Battery caps have no need for periodic replacement, you should only need a battery cap if you lose yours.
