Direct replacement for training-collar transmitters

This 7.2V 700mAh Ni-MH pack matches the original specifications for the 2200NCP, 1800NC, 2002B, 2000NC, 1802NC and 1600NCP transmitters.

Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Protection circuitry extends usable life

Built-in safeguards prevent the common failure modes that shorten battery lifespan in daily training use. Overcharge and over-discharge limits protect the chemistry during long charging cycles, while short-circuit protection adds safety if the pack is handled roughly. RoHS compliance confirms the materials are free from restricted substances.

Verify model and part number before ordering

Check that your transmitter is listed among the compatible models: 2200NCP, 1800NC, 2002B, 2000NC, 1802NC or 1600NCP. Also confirm the original battery part number matches PSU-BPRR, BP2T or BPRR. This pack will not fit transmitters outside that list or devices that require a different voltage or connector layout.

Questions about this item

How long before the 700 mAh Ni-MH pack needs replacing?

Expect one year of normal use before capacity drops enough to warrant a new pack.

What stops the 2200NCP transmitter running all day on this 5.04 Wh battery?

The 700 mAh capacity limits continuous run-time; heavy transmission will drain it in a single session.

Does the 142 g pack get hot during extended training-collar use?

Normal operation stays cool; built-in over-voltage and short-circuit protection prevents excess heat.
