That device is a compact, portable GPS navigator with Bluetooth connectivity for wireless data pairing during mobile navigation. Capacity is rated at 1000mAh (3.7Wh) — matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSocket Bluetooth GPS platform:\u003c\/strong\u003e\n    The receiver runs a single-cell 3.7V Li-ion architecture. The BMS monitors cell voltage directly and cuts power when the cell drops below the low-voltage threshold. No multi-cell balancing is involved — swap is straightforward once the housing is open.\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 GPS-class load profiles. The BMS accepted the cell without fault codes, and the protection circuit responded correctly to both full charge termination and low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start after power interruption:\u003c\/strong\u003e\n    After fitting this cell, power the GPS fully on outdoors before use. The receiver loses its satellite almanac data on full power removal and must perform a cold start — expect the first satellite fix to take 5–10 minutes. Subsequent warm starts return to under a minute once the almanac is rebuilt.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy reduced at low battery in the Socket receiver\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops below roughly 3.5V, some GPS receivers step down RF receiver sensitivity to reduce current draw. On the Socket Bluetooth GPS unit, this can appear as reduced position accuracy or slower fix updates before the device shuts off entirely. Users often notice position drift or signal dropouts well before the low-battery indicator appears. Replacing the cell restores full receiver sensitivity from the moment the unit powers on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without warning during active navigation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge or voltage-threshold indicator is uncalibrated against a new cell. The GPS reports adequate charge but hits the BMS low-voltage cutoff before the visual warning fires. The original aged cell had a compressed discharge curve — the new cell has a flatter curve that the indicator wasn't calibrated for. Run two full charge-to-cutoff cycles to let the device recalibrate its voltage-to-percentage mapping, and the warning should align with actual shutoff at or below 3.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377698570330,"sku":"BWCS-XEW01SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377698603098,"sku":"BWCS-XEW01SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377698635866,"sku":"BWCS-XEW01SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XEW01SL-1.webp?v=1778771896","url":"https:\/\/batteryweb.com\/products\/socket-communications-bluetooth-gps-receiver-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
