It supports the collar's GPS acquisition, cellular or radio communication, and continuous location reporting. Dimensions are 67.59 × 18.54 × 18.54mm — verify fitment before ordering if your collar housing has been modified.\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 collars share the same battery footprint, connector pinout, and BMS handshake protocol. Swapping between platforms does not require firmware changes — the BMS reads cell state on first power-up regardless of which device it's seated in.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full GPS-active discharge on a DC50 unit. The BMS held stable voltage through active satellite lock and flagged low-battery correctly at the expected threshold before cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst GPS acquisition after swap:\u003c\/strong\u003e\n    Take the collar outside immediately after installation and leave it stationary. Cold-start GPS acquisition — triggered any time power is fully interrupted — takes up to 10 minutes outdoors before the first fix registers in the Garmin app.\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 drains faster in low-signal rural areas\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen GPS signal is weak — dense tree cover, deep valleys, or areas with sparse satellite geometry — the collar's receiver runs longer acquisition cycles to maintain lock. Simultaneously, if the collar is using a cellular or radio uplink to reach a handheld unit at distance, transmit power ramps up. Both subsystems pulling harder at the same time accelerates discharge noticeably compared to open-field use. Expect shorter operating windows on hunts with heavy canopy versus flat, open terrain.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar shows charged but won't appear in the Garmin app after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a re-registration issue, not a battery fault. After a full power interruption, the collar loses its active Bluetooth and network session with the paired handheld or app. Power the collar on, then open the Garmin Hunting app or Alpha handheld and manually trigger a device search — don't wait for it to auto-connect. If the collar still doesn't appear, hold the power button for a full restart cycle and retry pairing from the app's device list.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360175652954,"sku":"BWCS-GDC50XL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360175685722,"sku":"BWCS-GDC50XL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360175718490,"sku":"BWCS-GDC50XL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GDC50XL-1.webp?v=1778610941","url":"https:\/\/batteryweb.com\/products\/garmin-dc50-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
