It fits the collar receiver units (SDT54-16683 and SDT54-16684) that handle remote stimulation signals during obedience training sessions. Dimensions are 25.90 × 20.50 × 5.30mm — measure your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYT-100 and YT-100S collar fit:\u003c\/strong\u003e\n    Both collar variants share the same receiver housing, connector pinout, and BMS handshake, so one cell covers the full YT-100 platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the YT-100 receiver board. The BMS accepted the cell without fault flags, and charge termination triggered cleanly at 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use activation on the collar:\u003c\/strong\u003e\n    After installing, power on the collar and place it outdoors for a full re-pairing cycle with the remote — the receiver resets its communication link after a power interruption and needs an active signal exchange to confirm pairing before training.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the YT-100 collar stops responding mid-session after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe YT-100 receiver uses a low-voltage cutoff in the 3.4–3.5V range. A cell with even moderate capacity fade can sag below that threshold under the brief current spike of a stimulation pulse, causing the collar to cut out without warning. A fresh 190mAh cell holds voltage more consistently under pulse load. If cutouts continue after fitting a new cell, check that the connector is fully seated — a partial connection adds resistance and makes sag worse.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar not pairing to the remote after installing a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA full power interruption clears the receiver's active pairing state. The collar does not automatically re-establish the link just because it powers on. You need to run the manual pairing sequence — hold the pairing button on the remote until the collar LED confirms the link. Check your transmitter is within 10 feet during this step, as the initial handshake uses a lower power signal than normal operating range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360140525658,"sku":"BWCS-SD166SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360140558426,"sku":"BWCS-SD166SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360140591194,"sku":"BWCS-SD166SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SD166SL-1.webp?v=1778610901","url":"https:\/\/batteryweb.com\/products\/sportdog-yardtrainer-yt-100-collar-replacement-battery-37v-190mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
