It fits the internal battery bay directly and restores power to the GPS receiver, display, and navigation software. Capacity matches the factory spec at 4.81Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNS-NCV43 fit:\u003c\/strong\u003e\n    The NS-NCV43 runs a single-cell 3.7V Li-Polymer pack with a compact footprint — 56.70 × 33.70 × 6.40mm. This cell matches that geometry and the BMS voltage thresholds the device expects for charge acceptance and low-battery cutoff.\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 under GPS-receiver-plus-display load. The BMS handshake completed without fault codes, and the device accepted a full charge from the internal charging circuit without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it acquire a full satellite fix before driving. A GPS performs a cold start after any complete power removal — first fix after a battery swap can take 5–10 minutes. Subsequent warm starts run under a minute once 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\"\u003eGPS accuracy reduced at low battery on the NS-NCV43\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NS-NCV43 scales back GPS receiver sensitivity as cell voltage drops toward the low-battery threshold. This is a firmware-level power-saving behaviour, not a hardware fault. When receiver sensitivity drops, the unit relies on fewer satellites and position accuracy degrades — you may see the blue dot drift or routes recalculate unexpectedly. Keeping the cell above 3.6V under load prevents the sensitivity reduction from triggering.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without warning before the low-battery indicator appears\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a battery swap, the NS-NCV43's charge gauge is uncalibrated to the new cell. The on-screen battery indicator can read one or two bars and then cut to black — no warning shown. This happens because the voltage-threshold mapping is based on the old cell's discharge curve, not the replacement. Run two full charge-to-cutoff cycles and the gauge recalibrates; after that, the indicator aligns with actual remaining capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377627824218,"sku":"BWCS-NSV430SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377627856986,"sku":"BWCS-NSV430SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377627889754,"sku":"BWCS-NSV430SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSV430SL-1.webp?v=1778771782","url":"https:\/\/batteryweb.com\/products\/insignia-ns-ncv43-replacement-battery-37v-1300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
