SportDog DC-22 Transmitter 1400 Compatible Battery 9.6V 700mAh

SportDog Transmitter 1400 / 1500 Series — 9.6V Ni-MH Replacement Battery (DC-22)

This 9.6V, 700mAh Ni-MH battery replaces the OEM DC-22 / BP-2T pack in the SportDog Transmitter 1400, Transmitter 1400NCP, Transmitter 1500, Transmitter 1500NCP, and sixteen additional compatible transmitter variants. It restores power to the handheld unit that sends correction signals and tone commands to SportDog receiver collars. Voltage, connector, and physical dimensions match the factory spec at 43.32 × 41.08 × 20.69mm.

• Transmitter 1400 and 1500 platform compatibility: Both series use the same 9.6V Ni-MH cell stack, physical housing footprint, and connector locking tab — which is why one part number covers both lines. Swapping between NCP and standard variants requires no modifications.
• Bench tested on actual hardware: We cycled this battery through charge and discharge on a Transmitter 1400 unit. The transmitter accepted the pack without error, and the charge indicator tracked normally from depleted to full without interruption.
• Ni-MH transmitter conditioning tip: If the transmitter was left unused with a fully discharged original pack for several months, run two full charge-discharge cycles before field use — Ni-MH cells that have sat at zero volts can show artificially low capacity on the first cycle until the chemistry restabilises.

Why the Transmitter 1400 shows "low battery" immediately after a fresh charge

Ni-MH packs have a relatively flat discharge curve, so the transmitter's fuel gauge relies heavily on voltage at rest rather than coulomb counting. If the battery was stored partially discharged, the resting voltage can read below the transmitter's threshold even after a short charge completes. The fix is a full, uninterrupted charge cycle — typically until the charger's indicator switches from charging to standby. After that, a brief 30-minute rest lets the cell voltage stabilise before the transmitter takes a fresh reading.

Transmitter powers on but collar does not respond to commands

This is rarely a collar fault — the transmitter's RF output drops significantly when battery voltage sags under load, even if the unit appears on. A Ni-MH pack that has memory effect or partial capacity loss can read 9.6V at rest but drop to 8V or below the moment the transmitter keys a signal. Check resting voltage with a multimeter: anything below 9.0V under no-load suggests a degraded cell. Fully charge the replacement pack and retest — a healthy battery holds above 9.2V during active transmission.
