It replaces OEM part numbers 361-00029-02, 010-10806-30, and 010-11828-03. If your DC50 won't hold a charge through a full day in the field, this is the swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC50, Alpha, and TT10 compatibility:\u003c\/strong\u003e\n    These devices share the same 3.7V cell format, connector pinout, and BMS handshake protocol — that's why one battery covers the full tracking system. Swapping cells across the collar and handheld receiver uses the same replacement.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the DC50 platform. The BMS accepted the cell without fault codes, held the rated voltage through load cycles, and the protection circuit responded correctly to cutoff thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst GPS fix after reinstall:\u003c\/strong\u003e\n    After installing, take the dog outside and allow 5–10 minutes for the first GPS acquisition. The DC50 performs a cold start after any power interruption — almanac data is cleared and the receiver must rebuild satellite lock from scratch. Subsequent warm-start updates are significantly faster.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DC50 battery drains faster in rural and low-signal areas\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIn open country with sparse cellular coverage, the DC50's GPS and cellular radios both ramp up transmit power to maintain signal. This draws significantly more current than operation in areas with strong coverage. Active tracking mode — where the collar reports position continuously — pulls harder on the cell than periodic reporting mode. If your hunts run long in remote terrain, switch to a longer reporting interval in Garmin Basecamp or the Alpha's settings to reduce draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDC50 collar not syncing to the Alpha receiver after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a power interruption, the TT10 or DC50 collar loses its active pairing session with the Alpha handheld — it doesn't automatically re-register. Power both units on and navigate to Dog List on the Alpha, then select the collar and re-establish the link manually. If the collar doesn't appear, hold the collar's power button until the LED flashes and the unit re-advertises. The Alpha should detect it within 60 seconds at close range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360176078938,"sku":"BWCS-GDC50SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360176111706,"sku":"BWCS-GDC50SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360176144474,"sku":"BWCS-GDC50SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GDC50SL-1.webp?v=1778610941","url":"https:\/\/batteryweb.com\/products\/garmin-dc50-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
