Will this fit my SportDOG transmitter?

It is made for YardTrainer and SD-425 series transmitters. Check the model printed on your handheld before ordering; other SportDOG series use different cells.

Does it come with a charger?

No. The kit has the rechargeable battery, gasket, screwdriver and operating guide. Use the charger you already have for the transmitter.

How long does the battery last per charge?

SportDOG does not publish a runtime figure for this kit. Expect performance close to the original cell, which depends on how much you use tone and vibration.

Is it hard to install?

No. The included screwdriver and guide walk you through opening the housing, swapping the cell and reseating the gasket. Take care with the gasket so the transmitter keeps its water resistance.

Should I buy this or a new transmitter?

If the handheld works and only the battery has failed, the kit is the cheaper fix. If the buttons or screen are also failing, a new transmitter makes more sense.

Prices for this kit swing by seller, and it is a low-volume part, so compare listings and check the price history before buying.

Our take on the Transmitter Battery Kit (SD-425 Series)

This is a replacement battery kit for SportDOG YardTrainer and SD-425 series handheld transmitters, not a collar or a full training system. It ships with a rechargeable battery, a gasket, a screwdriver and an operating guide, so you can swap the cell yourself when the handheld stops holding a charge. It is a small, low-cost part; check the current price against other SportDOG battery listings before ordering, since a kit price can vary widely by seller.
