SportDog RFA-67 SBC-6 Replacement Battery 6V 150mAh

SportDog SBC-6 / SBC-18 — 6V Li-MnO2 Replacement Battery (RFA-67)

This is a 6V, 150mAh lithium-manganese dioxide battery for the SportDog SBC-6, SBC-18, and Premium Bark Control Collar. It replaces OEM part numbers RFA-67 and RFA-67D-11. When the original cell depletes, the collar loses stimulation and vibration output entirely — this cell restores both functions.

• SBC-6, SBC-18, and Premium Bark Control compatibility: These collars share the same 6V coin-format battery bay, connector orientation, and discharge profile. The stimulation circuit draws short, high-current pulses; the Li-MnO2 chemistry handles that pulse load without the voltage droop that NiMH cells show under the same demand.
• Bench tested on actual hardware: We ran this cell through stimulation and vibration cycles on a SportDog collar test rig. The battery held nominal voltage through repeated pulse draws, and the collar's low-battery indicator did not trigger until the cell reached its rated cutoff threshold.
• First-use seating tip: Li-MnO2 cells can show a slightly elevated open-circuit voltage when new. Seat the battery firmly, close the contact cap fully, and run one short stimulation test before fitting the collar — this confirms contact closure and lets the cell settle to its working voltage under load.

Why the SBC-6 shows no stimulation output even with a fresh battery installed

The SBC-6 stimulation circuit requires a stable 6V supply at the contacts. If the battery cap is not fully seated, contact resistance rises and the circuit sees a voltage drop before it can fire. Li-MnO2 cells are also sensitive to storage temperature — a cell stored below 0°C can show a temporary voltage suppression for several minutes after installation. Check that the rubber cap is flush, wipe both contacts clean with a dry cloth, and run a test trigger from the remote at close range before assuming the battery is faulty.

Collar draining faster than expected between training sessions

The SBC-6 uses a receiver circuit that stays in a low-power listening state between activations — this standby draw is small but continuous. If the collar sits unused for several weeks, that standby load can fully deplete a 150mAh cell even without a single stimulation event. Li-MnO2 chemistry also has a finite shelf self-discharge rate, so a cell already sitting in storage before sale starts below full capacity. Remove the battery from the collar if it will not be used for more than two weeks, and check open-circuit voltage with a multimeter — a fresh Li-MnO2 cell at rest should read approximately 6.4V.
