Dogtra BP20R Receiver 175NCP Compatible Battery 3.6V 210mAh

Dogtra Receiver 175NCP / 200NCP Series — 3.6V Ni-MH Replacement Battery (BP20R)

This is a 3.6V, 210mAh Ni-MH battery for the Dogtra receiver collar. It fits the Receiver 175NCP, 200NCP, 202NCP, 280NCP, and more than 22 additional Dogtra receiver units. The BP20R cell slot is shared across this entire collar family, so one part number covers the full range.

• Receiver collar compatibility: The 175NCP, 200NCP, 202NCP, and 280NCP all share the same 3.6V cell bay and connector. Dogtra standardised this across the series so trainers running multiple dogs on different collar models can stock one replacement cell.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Dogtra receiver unit. The BMS accepted the cell cleanly, completed charge termination at the correct voltage, and the stimulation circuit responded normally throughout.
• Post-swap activation tip: After fitting the new cell, pair the receiver to the transmitter before the first training session — some units drop their pairing state when power is fully cut, and attempting a correction without confirming the link first will produce no response from the collar.

Why the Dogtra 175NCP receiver stops responding mid-session

Ni-MH cells at this capacity have a steep voltage drop curve once charge falls below 40%. The Dogtra receiver's protection circuit cuts stimulation output before the cell reaches full depletion to protect the electronics. This looks like a dead collar but the unit is still powered — the output stage has simply shut down. Recharging immediately rather than waiting restores full function; repeated deep discharges accelerate capacity loss in Ni-MH chemistry.

Collar powers on but delivers no stimulation after a new cell is fitted

This is almost always a lost transmitter pairing rather than a faulty cell. When the receiver loses power entirely — including during a battery swap — some Dogtra units reset their link memory. The transmitter is still sending, but the receiver is no longer registered to it. Hold both units in pairing mode as described in the 175NCP manual to re-establish the link. Once paired, test with the lowest correction level before putting the collar back on the dog.
