It fits the EDT, EZT, ST, and RH series, plus 14 additional DT Systems collar models. Swap it in when the original pack no longer holds a charge through a full training session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEDT \/ EZT \/ ST \/ RH platform compatibility:\u003c\/strong\u003e\n    These collar models share the same 4.8V Ni-MH cell configuration, connector pinout, and charge management circuit. That common architecture is why one battery covers all of them — the receiver circuitry expects the same voltage rail across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a DT Systems receiver. The onboard charge circuit accepted the pack without fault, and cell voltage held within spec across multiple cycles with no BMS interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH conditioning on DT Systems collars:\u003c\/strong\u003e\n    DT Systems collar chargers use a trickle-charge profile tuned for Ni-MH chemistry. Do not leave the collar on the charger for more than the time specified in your model's manual — Ni-MH cells develop voltage depression faster than other chemistries when overcharged on trickle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the collar stimulus stops firing mid-session after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells deliver a flatter discharge curve than alkaline, but they drop off sharply once capacity is exhausted. If the collar cuts out during active use shortly after a swap, the new pack may not have received a full initial charge. DT Systems chargers need a complete charge cycle — partial charges on a fresh Ni-MH pack leave less usable capacity than the rated 300mAh. Connect the collar to the charger until the indicator confirms a full charge before the next session.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar not responding to the transmitter after installing the new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA power interruption clears the active pairing state on many DT Systems receivers. After fitting the new battery, the collar and transmitter may need to re-link. Hold the transmitter's power button until the LED blinks, then press the collar's power button to re-enter pairing mode — the exact sequence varies by model, so check your manual. If the collar still won't respond, verify the pack is seated fully and the terminal contacts are clean, then confirm pack voltage is at or above 4.5V with a multimeter before re-pairing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360185319514,"sku":"BWCS-SDC01SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360185352282,"sku":"BWCS-SDC01SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360185385050,"sku":"BWCS-SDC01SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDC01SL-1.webp?v=1778610941","url":"https:\/\/batteryweb.com\/products\/dt-systems-edt-replacement-battery-48v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
