Replacement Battery for Sportdog 425 Trainers

This Li-Polymer cell replaces the SAC54-13734 pack used in FieldTrainer 425 and SD-425 series transmitters. It delivers 3.7V and 190mAh capacity in a compact black housing. The unit is brand new and built to 100% OEM compatibility.

Questions about this item

How do I install the DS-CS-SD425SL battery in my Sportdog SD-425 transmitter and what step is often missed?

Open the transmitter battery compartment, align the 25.90 x 20.48 x 5.20 mm pack with the correct polarity, press it fully into the connector until it clicks, then reseal the waterproof cover — the step most people skip is checking the gasket sits flat before tightening the screws.

What maintenance will this 3.7V 190mAh Li-Polymer pack need over time?

Recharge it after each training session using the Sportdog charger; store at roughly half charge if unused for weeks, keep contacts clean, and expect to replace the pack once runtime drops noticeably — typically after several hundred charge cycles.

What limit appears first during a long training day with the SD-425 remote?

The 0.70 Wh capacity will deplete before any thermal limit; continuous transmission drains the 190 mAh cell in a few hours, so plan to recharge or swap the battery between sessions.
