PetStop Elite Dog Collar 6V 160mAh Silver Oxide Replacement Battery

PetStop Elite / Ultra Elite Series — 6V Silver Oxide Replacement Battery

This is a 6V 160mAh silver oxide replacement battery for PetStop dog containment collars. It fits the Elite, Ultra Elite, Ultra Elite 2, and Ultra Tuff models. Silver oxide chemistry gives this battery a flat discharge curve, which means the collar's warning tone and correction circuits get stable voltage until the cell is nearly exhausted.

• Elite and Ultra Tuff platform fit: These four collar models share the same battery bay geometry and voltage requirement — 6V at a compact 21.67 × 12.00 × 12.00mm footprint. The silver oxide cell type is specified because the collar's correction circuitry needs consistent voltage output, not the sloping curve you get from alkaline cells of the same size.
• Bench tested on actual hardware: We ran this cell against the collar's tone and vibration trigger cycles and confirmed the BMS draws a clean load without voltage sag at the correction thresholds the Elite platform uses.
• First use after install: After swapping the battery, keep the collar powered on and take the dog outside for at least five minutes before putting it back into service — the collar re-syncs its boundary calibration on first power-up and needs active signal to complete that handshake.

Why the Ultra Elite collar drains faster near property boundaries

PetStop containment collars increase signal polling frequency when the dog is near the boundary wire. The collar's receiver is actively comparing signal strength more often in that zone, which pulls more current from the 160mAh cell than idle periods in the centre of the yard. In smaller yards, a dog that patrols the fence line regularly will deplete the cell faster than the rated cycle count suggests. Reducing the boundary width in the transmitter settings — where the system allows it — cuts the time the collar spends in high-poll mode.

Collar shows no response after battery replacement

If the collar produces no tone or vibration after a fresh cell is installed, the contact points inside the battery bay are the first place to check — silver oxide cells require a clean metal-to-metal connection, and any corrosion from the depleted cell will block current flow entirely. Wipe the contacts with a dry cloth or a pencil eraser, then reseat the battery firmly. If the collar still does not respond, confirm the replacement cell reads at least 5.8V under a basic load test before concluding the collar itself has a fault.
