Compatible replacement battery

This 7.4V 200 mAh Li-Pol cell is built to fit the SportDOG HoundHunter 3225 SD-3225 receiver collar. It measures 27x41x6mm and supplies the voltage and capacity the original pack requires. The pack is sold as a single unit in new condition. It is not an OEM component but a direct replacement from HQRP.

Includes HQRP Coaster accessory

The bundle adds a branded coaster that serves as a charging cradle for the battery. This accessory lets you dock the cell for recharging without soldering or extra cables. No software, drivers or additional adapters are supplied in the package.

Check collar model and space before ordering

Verify that your training collar is the HoundHunter 3225 or SD-3225; other SportDOG models may use a different pack shape or connector. Confirm the 27x41x6mm footprint matches the battery compartment. Buyers who need a multi-pack or a higher-capacity cell should look elsewhere.

Questions about this item

How often will this 200 mAh Li-Pol pack need replacing under daily training use?

Expect roughly one to two seasons before capacity drops enough to shorten collar run-time, then swap in a fresh 7.4 V pack.

What stops the collar first during a long hunt — voltage sag or thermal limit?

Voltage sag appears first; the 200 mAh cell cannot sustain high transmit current for extended periods without the voltage dipping below the receiver's cut-off.

Does the 27 x 41 x 6 mm pack get warm or draw extra current when the collar runs all day?

It stays near body temperature and draws only the collar's normal operating current; no noticeable heat or extra power drain occurs.
