It fits the compact wireless GPS unit used with smartphones and tablets for field navigation and data logging. Dimensions are 52.90 × 32.50 × 7.50mm — confirm these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBluetooth GPS receiver platform:\u003c\/strong\u003e\n    This cell powers the onboard GPS chipset and Bluetooth radio simultaneously. Both run off the same 3.7V rail, so the battery must sustain stable output across both loads without voltage sag causing a BMS disconnect mid-use.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through combined GPS-lock and Bluetooth transmission loads. The BMS held cutoff voltage cleanly under dual-draw conditions and returned to charge without requiring a re-initialisation cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it acquire a full satellite fix before use. GPS hardware runs a cold start after any full power interruption — first fix after a swap takes 5–10 minutes. Subsequent warm starts return to under a minute once ephemeris 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\"\u003eGPS accuracy dropping at low battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome GPS receivers reduce receiver sensitivity as battery voltage falls below roughly 3.5V to cut current draw. When that happens, the unit holds fewer satellite signals, which widens the position error circle. You may notice routes drifting or position jumping between fixes. Keeping the cell above 3.6V under load is the practical threshold for full receiver performance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shutting off without low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge in this receiver calibrates its capacity estimate against the installed cell. A new cell initially reads uncalibrated, so the indicator can skip warning stages and trigger BMS cutoff abruptly at around 3.2V. Run two or three full charge-discharge cycles through normal GPS use to let the gauge recalibrate. After that, the low-battery warning will appear at the correct threshold before shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377710497882,"sku":"BWCS-GR230SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377710530650,"sku":"BWCS-GR230SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377710563418,"sku":"BWCS-GR230SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GR230SL-1.webp?v=1778771839","url":"https:\/\/batteryweb.com\/products\/socketmobile-communications-bluetooth-gps-receiver-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
