Dogtra BP37W 280C Receiver Compatible Battery 3.7V 300mAh

Dogtra 280C / 282C Receiver — 3.7V Li-Polymer Replacement Battery (BP37W)

This is a 3.7V, 300mAh Li-Polymer battery for the Dogtra 280C Receiver, 282C Receiver, and Trainers ARC collar units. It slots in as a direct swap for the original BP37W. At 26.72 x 19.70 x 7.00mm, it matches the factory cell geometry exactly.

• 280C, 282C, and Trainers ARC compatibility: These three receivers share the same battery bay dimensions, connector pinout, and 3.7V operating rail. The BMS handshake is identical across the platform, so one cell covers all three units.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the 280C receiver. The BMS accepted the charge curve without fault codes, and stimulation output held consistent across the full discharge cycle.
• Post-install pairing check: After fitting a fresh battery, hold the receiver's power button until the indicator light cycles — the collar re-registers to the transmitter and confirms the communication link before the first correction can fire.

Why the 280C receiver loses transmitter link after a battery swap

Cutting power to the receiver clears its volatile pairing register. When you install the new cell, the unit boots fresh and waits for a link signal rather than resuming the previous paired state. Hold both the transmitter and receiver power buttons simultaneously until both indicator lights confirm sync — the exact sequence is in the Dogtra pairing guide for the 280C series. If stimulation output is unresponsive after that, check that the transmitter's contact points are clean and the correction level is set above zero before testing.

Collar indicator light flashing but no stimulation output after new battery

A flashing light with no output usually means the battery voltage hasn't cleared the receiver's low-voltage threshold post-install. This happens when the replacement cell shipped at a partial state of charge. Charge the collar fully via its dock until the indicator shows solid green, which typically corresponds to a resting cell voltage of 4.1–4.2V. Run a short stimulation test at a mid-range level before taking it into the field.
