It restores full power to the device for outdoor navigation, waypoint logging, and route tracking. Dimensions are 50.22 × 36.88 × 6.52mm — verify against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGPS-3741 compatibility:\u003c\/strong\u003e\n    The GPS-3741 runs a single-cell 3.7V Li-ion architecture with no active BMS handshake on the battery side — the protection circuit sits on the cell itself. This cell matches that voltage rail and physical footprint directly.\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 a GPS-3741 unit. The onboard protection circuit triggered correctly at low-voltage cutoff, and the device recognised full charge state without error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-fix cold start after swap:\u003c\/strong\u003e\n    After fitting this cell, power the GPS on outdoors and let it acquire a satellite fix before use. Full power removal triggers a cold start — first fix takes 5–10 minutes. Subsequent warm starts drop to under a minute once almanac data 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-3741 shutting off without warning at low battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a battery swap, the GPS-3741's charge indicator can read inaccurately until the device completes a full charge-discharge calibration cycle. The device's low-battery threshold may trigger a hard shutoff before the on-screen indicator shows critical. This happens because the fuel gauge recalibrates against actual cell capacity over the first few cycles. Run the device to shutoff once, then charge to 100% — the indicator aligns after that.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved routes missing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome GPS-3741 route and POI data is held in battery-backed RAM, which loses state the moment the cell is removed. This is not a fault with the replacement cell — it is a consequence of full power interruption during the swap. Before removing the old battery, export saved routes via the USB connection to a computer. Reload them after the new cell is fitted and the device has completed its first satellite fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377724784730,"sku":"BWCS-BM6300SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377724817498,"sku":"BWCS-BM6300SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377724850266,"sku":"BWCS-BM6300SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BM6300SL_1.webp?v=1778771839","url":"https:\/\/batteryweb.com\/products\/jucon-gps-3741-replacement-battery-37v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
