It fits the OEM part numbers 361-00029-02, 010-10806-30, and 010-11828-03. The battery powers GPS acquisition, position transmission, and collar radio communication during active tracking sessions in the field.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC50, TT10, and Alpha collar compatibility:\u003c\/strong\u003e\n    These collar and handheld units share the same 3.7V battery platform and connector spec. The BMS handshake is consistent across the DC50 and TT10 collar hardware, so the same cell works across the family without modification.\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 GPS-active discharge cycles on DC50 hardware. The BMS held cutoff at the expected low-voltage threshold and accepted a full charge cycle without error flags from the Garmin firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst GPS acquisition after install:\u003c\/strong\u003e\n    After fitting this battery, take the dog outside before powering off. The collar performs a cold start after any power interruption — first GPS fix can take 5–10 minutes outdoors. Subsequent warm-start updates are significantly faster once the almanac data is cached.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDC50 collar battery draining faster in remote hunting areas\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIn areas with weak GPS signal or no cellular coverage, the DC50 collar increases its acquisition polling rate to maintain a position lock. This draws significantly more current than normal periodic-reporting mode. The collar's radio transmitter also boosts output power when the paired Alpha handheld is at range limits. If you're hunting in dense canopy or hilly terrain, expect noticeably shorter tracking sessions compared to open-ground use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar not showing up in the Alpha after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a full power interruption, the TT10 or DC50 collar loses its active pairing session with the Alpha handheld. The collar doesn't automatically re-register — it waits for a new sync request. Power both units on, navigate to the Dog List on the Alpha, and re-add the collar using its ID. The pairing process takes under a minute and restores full tracking and bark\/contact functions.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360158056538,"sku":"BWCS-GDC50HL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360158089306,"sku":"BWCS-GDC50HL-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360158122074,"sku":"BWCS-GDC50HL-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GDC50HL-1.webp?v=1778610901","url":"https:\/\/batteryweb.com\/products\/garmin-dc50-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
