It matches the OEM part number 604060(140) and fits the physical bay without modification. Capacity figures are taken directly from the product specification — 5.18Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNS-NCV20 fit:\u003c\/strong\u003e\n    The NS-NCV20 uses a single-cell Li-Polymer pack at 3.7V nominal. This cell matches that voltage rail and the 60.75 × 36.26 × 5.30mm footprint, so the connector seats correctly and the BMS reads state-of-charge without calibration errors.\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 navigator hardware. The BMS reported accurate state-of-charge from the first cycle and did not trigger false low-voltage cutoffs during active navigation sessions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start tip for the NS-NCV20:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it acquire a satellite fix before driving. The NS-NCV20 performs a cold start after any full power interruption — first fix can take 5–10 minutes, while subsequent warm starts lock in under a minute.\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-NCV20\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage drops toward 3.4V, some GPS navigator units reduce RF receiver sensitivity to cut current draw. On the NS-NCV20 this shows up as position drift or a wider accuracy circle on-screen. It is not a satellite signal issue — it is a deliberate power-saving response in the receiver firmware. Keeping the battery above 3.6V during active navigation avoids the sensitivity reduction entirely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNS-NCV20 shutting off without warning before the battery indicator empties\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA degraded or freshly swapped cell can cause the NS-NCV20 to cut power abruptly while the on-screen indicator still shows one or two bars. The fuel gauge in this unit is voltage-based, not coulomb-counted, so the indicator loses accuracy when cell internal resistance changes. A new cell recalibrates over two to three full charge-discharge cycles. Run two complete cycles — charge to 4.2V, use until auto-shutdown — and the indicator will track remaining capacity correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377627562074,"sku":"BWCS-NSV200SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377627594842,"sku":"BWCS-NSV200SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377627627610,"sku":"BWCS-NSV200SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSV200SL-1.webp?v=1778771783","url":"https:\/\/batteryweb.com\/products\/insignia-ns-ncv20-replacement-battery-37v-1400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
