PetSafe RFA-67 6V Lithium 2-Pack

Two 6 volt lithium metal replacement batteries designed for PetSafe bark collars, in-ground fence and wireless fence receiver collar systems. Each module is waterproof with a built-in gasket seal so it keeps working during swimming, rain or sprinkler play. The pack suits owners who need a ready spare for continuous containment or bark control.

Upgrade from single or depleted cells

Replacing a single exhausted cell with this twin pack restores full voltage and waterproof integrity, avoiding the risk of a loose generic fit that can break the seal. The jump is worth it when the collar starts signalling low power or the original battery passes the 1–3 month service window.

Check collar model and housing

Verify the receiver collar is listed as compatible — Basic Bark Collar, Stay & Play Wireless Fence, Wireless Containment System, Basic In-Ground Fence or Deluxe UltraLight Collar — and confirm the battery housing accepts the RFA-67D-11 form factor before ordering.

Questions about this item

What collar models does the RFA-67 6V lithium battery fit?

The RFA-67 fits PetSafe Basic Bark Collar, Stay & Play Wireless Fence collar, Wireless Containment System collar, Basic In-Ground Fence collar and Deluxe UltraLight collar.

How do I install the RFA-67 battery in the collar housing?

Insert the PetSafe test light tool or a coin into the battery housing slot, turn counter-clockwise to remove the old module, insert the new RFA-67, then turn clockwise until secure and reseal firmly.

How often will I need to replace the RFA-67 batteries?

Each RFA-67 lasts 1–3 months depending on how often the collar activates; dogs that bark frequently or test the fence boundary regularly will drain the battery faster.
