PetStop OT200 Replacement Battery 7.5V 160mAh Alkaline

PetStop OT200 / PST06 — 7.5V Alkaline Replacement Battery

This is a 7.5V 160mAh alkaline battery for the PetStop OT200 dog fencing collar and PST06 receiver. It powers the receiver unit worn by the dog — the component that detects the boundary signal and delivers corrective stimulation. Swap it when the collar stops responding to the fence perimeter or the indicator shows a low-power warning.

• OT200 and PST06 compatibility: Both the OT200 and PST06 receiver collars run the same 7.5V power rail and share an identical battery footprint at 27.80 × 12.40 × 12.40 mm. One battery fits both units without modification.
• Bench tested on actual hardware: We ran this battery in an OT200 receiver and confirmed the collar powered on, registered the fence signal, and delivered corrective output at rated voltage. No false triggers or signal dropout during the test cycle.
• Receiver reactivation after swap: After installing a fresh battery, walk the dog to the boundary wire and confirm the receiver beeps or activates at the correct distance — corrective threshold calibration can drift if the old battery discharged slowly over weeks, and a boundary check resets your reference point.

Why the OT200 receiver stops triggering at the boundary

The OT200 receiver needs stable voltage to detect the low-frequency signal broadcast by the boundary wire. As the alkaline cell drops below the collar's minimum operating threshold, the receiver's signal detection circuit loses sensitivity before the collar appears fully dead. The dog can cross the boundary without correction even though the collar still shows a faint power reading. Replacing the battery restores full detection sensitivity — a partially depleted alkaline is not a functioning collar.

Collar shows power but delivers no correction at the fence line

This symptom usually means the battery voltage has sagged under the brief load spike the correction circuit draws. Alkaline cells maintain resting voltage longer than they maintain load voltage — the collar reads alive at rest but browns out the moment correction output is requested. Remove the battery and check resting voltage with a multimeter; anything below 7.0V under no load on a 7.5V alkaline cell means it needs replacing. Install a fresh cell and retest correction output at the boundary wire.
