Replacement Battery for Dogtra Collars

This Centenex Electronics NiMH cell delivers 210 mAh at 3.6 V for Dogtra training and containment receivers. It fits models such as the YS-500, 280NCP, 300M and 7000M series. The pack replaces part numbers DC20 and 20AAAH3BMX with a direct plug-in design.

Thermals Noise and Power Draw

Nickel-metal-hydride chemistry provides stable voltage across the discharge cycle with no memory effect. Self-discharge is low during seasonal storage. The 0.76 Wh capacity supports typical correction cycles without measurable heat build-up in the receiver housing.

Capacity Decides Fit

At 210 mAh the cell matches the original specification for the listed Dogtra collars. Buyers whose units require a higher milliampere-hour rating will find this pack undersized for their application.

Questions about this item

How do I fit the 30 x 25.15 x 9 mm NiMH pack into my Dogtra receiver and which orientation catches people out?

Slide the pack in with the labelled side facing the contact springs; the 9 mm height sits flush only one way round, so reverse it if the cover will not latch.

What part will need replacing after a few hundred charge cycles on this 210 mAh 3.6 V cell?

The whole sealed battery; NiMH chemistry degrades with cycling and the pack is not user-serviceable, so order a fresh Centenex unit when run-time shortens.

Which limit appears first during a long training session with the 0.76 Whr capacity?

Voltage sag under continuous transmit; the small 210 mAh pack drops below the receiver's cut-off after extended stimulation bursts, ending the session early.
