DUSLAN RFA-67 6 V lithium standard battery 10-pack

PetSafe Compatible Fence & Dog Collar Batteries

The DUSLAN RFA-67 10-pack supplies 6 Volt lithium cells built for PetSafe containment collars and bark collars. Each unit carries a minimum six-year shelf life and a waterproof seal rated for all-season outdoor use. A coin-slot design allows tool-free replacement and the cells install in either orientation. Pet owners maintaining invisible fences or training collars can keep spares on hand without worrying about rapid self-discharge.

Thermals Noise and Power Draw

Lithium chemistry delivers a stable 6 Volt output with negligible self-discharge during storage. No active cooling or fan is required and the sealed construction produces no audible noise in operation. Current draw matches the low intermittent pulses of compatible fence and bark collars, so the pack sustains normal containment cycles without voltage sag. The waterproof seal prevents moisture ingress that could otherwise increase internal resistance over time.

Upgrade Path and Value

This pack replaces disposable alkaline or older lithium cells in the listed PetSafe and SportDog models, including PIF-300, PRF-3004W, RF-304, SBC-6 and SBC-18 units. The jump is worthwhile when a collar shows shortened run-time or when a household runs multiple collars and wants a single bulk purchase. Builders needing rechargeable packs or proprietary form factors outside the RFA-67 specification should look elsewhere.
