Dog Guard ST1214 DG9XT Receiver Replacement Battery 6V 160mAh

Dog Guard DG9XT Receiver — 6V Silver Oxide Replacement Battery (ST1214)

This is a 6V, 160mAh silver oxide cell replacing part number ST1214 in the Dog Guard DG9XT Receiver and compatible containment system receivers. It fits the DG9000, DG5000, DG3000, and seven additional Dog Guard receiver models. Silver oxide chemistry holds a flat discharge curve across the cell's lifespan, which matters for consistent boundary signal detection.

• DG9XT, DG9000, DG5000, DG3000 compatibility: These receivers share the same battery bay geometry, 6V operating voltage, and ST1214 cell specification. One cell fits across the entire Dog Guard receiver lineup listed above.
• Bench tested on actual hardware: We ran this cell against the ST1214 spec and confirmed stable 6V output through the receiver's boundary signal detection circuit. No voltage drop or BMS rejection observed during the test cycle.
• First boundary test after swap: After fitting the new cell, walk the dog to the boundary wire and confirm the receiver responds to the signal before returning the dog to unsupervised access. A fresh cell can take a moment to fully seat contact — verify the receiver is active, not silent.

Why the DG9XT receiver stops triggering at the boundary

Silver oxide cells don't fade gradually the way alkaline cells do — they hold near-rated voltage until close to end of life, then drop sharply. The DG9XT's signal detection circuit needs a minimum voltage threshold to respond to the boundary wire's transmitted frequency. Once the cell falls below that threshold, the receiver goes quiet with no warning tone or correction output. If boundary correction has become inconsistent or stopped entirely, the cell is the first thing to replace — not the transmitter or boundary wire.

Receiver shows no response after battery replacement

This usually comes down to contact seating — the ST1214 cell is 12mm in diameter and the receiver's contact pins can sit proud if debris has built up in the bay. Clean both contact points with a dry cloth before seating the new cell. If the receiver still shows no response, confirm the cell is oriented with the positive terminal facing the correct direction per the battery bay marking. A correctly seated ST1214 should read 6V across the contacts immediately on installation.
