It matches the OEM cell format at 50.00 × 35.95 × 6.92mm, fitting the battery bay without modification. Capacity is 4.44Wh — identical to the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN30 \/ N40 \/ N80 \/ N120 compatibility:\u003c\/strong\u003e\n    These four Falk navigator models share the same battery bay dimensions, connector pin-out, and 3.7V single-cell architecture. The CL653450APR 1S1P cell format was used across this product generation, so one replacement covers the full group.\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 a Falk N-series unit. The BMS accepted the cell without fault flags, voltage regulation held steady across the GPS receiver and display load, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start tip after fitting:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors before driving and let it acquire a satellite fix from a stationary position. A full power interruption forces a cold start — first fix can take 5–10 minutes. Once acquired, subsequent warm starts drop to 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 while navigating near the end of a charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSeveral Falk N-series units reduce GPS receiver sensitivity at low battery voltage to extend available power. This shows up as position drift or slower route recalculation, not a software fault. The receiver is pulling back its sampling rate to stay within the power budget the BMS is allowing at low state-of-charge. Keeping the cell above 3.6V during active navigation keeps the receiver running at full sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFalk N30 shuts off without warning instead of showing a low-battery indicator\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery gauge in the unit is no longer calibrated to the actual cell's voltage curve. The on-screen indicator may still show one bar when the cell has already dropped below the BMS cutoff threshold, so the unit cuts power with no visual warning. The fix is a full calibration cycle — run the new cell down until the unit shuts itself off, then charge to 100% without interruption. After one full cycle the indicator aligns with the real voltage curve and early shutoff stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377626939482,"sku":"BWCS-FKN30SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377626972250,"sku":"BWCS-FKN30SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377627005018,"sku":"BWCS-FKN30SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FKN30SL_1.webp?v=1778771766","url":"https:\/\/batteryweb.com\/products\/falk-n30-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
