It fits Delta, Delta Upland, Delta Handheld, and Delta Sport XC units. Swap it when the original cell no longer holds a charge through a full day in the field.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDelta collar family fit:\u003c\/strong\u003e\n    All Delta-series collars share the same battery bay dimensions and 3.7V power rail. The BMS handshake is consistent across Delta, Delta Upland, and Delta Sport XC hardware, so one cell covers the full range without firmware issues.\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 Delta collar hardware. The BMS accepted charge without flagging an incompatible cell, and voltage held within the expected window across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst GPS fix after installation:\u003c\/strong\u003e\n    After fitting the new battery, take the dog outside and allow 5–10 minutes for the collar to complete its cold-start GPS acquisition. Power interruption clears the almanac cache, so the first satellite fix after a swap takes longer than the warm-start updates the collar normally runs.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Delta collar drains faster in open rural terrain\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIn areas with weak GPS signal, the receiver stays active longer to maintain a position lock — drawing more current than it would with a clear sky view. Dense tree canopy and steep valley terrain force the same effect. Active tracking mode polls position continuously and transmits to the handheld unit, which compounds the draw compared to periodic-reporting mode. If the collar is running dry faster than expected, switch the handheld to a longer update interval when the dog is working in open country where frequent pings are less critical.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDelta collar not syncing to the handheld after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA full power cycle clears the collar's active pairing session with the handheld unit. The handheld does not automatically re-establish the link — it needs a manual re-registration step. Power both devices on within range of each other, then use the handheld's device list to re-acquire the collar. Once linked, confirm the collar ID appears on the handheld map screen before heading into the field.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360167657562,"sku":"BWCS-GMR864SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360167690330,"sku":"BWCS-GMR864SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360167723098,"sku":"BWCS-GMR864SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMR864SL-1.webp?v=1778610941","url":"https:\/\/batteryweb.com\/products\/garmin-delta-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
