It replaces OEM part PR-3750159 and fits the 10.1-inch NS-15AT10 model directly. Swap it in when the original cell no longer holds enough charge to get through a normal session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNS-15AT10 fitment:\u003c\/strong\u003e\n    The NS-15AT10 runs a single-cell 3.7V lithium-polymer architecture with a flat ribbon connector and an onboard fuel gauge IC. This replacement matches that voltage rail, connector pitch, and cell profile — the BMS on the tablet's charge IC handshakes without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the NS-15AT10 mainboard. The charge IC accepted the cell on the first cycle, BMS protection tripped correctly at low-voltage cutoff, and the fuel gauge began tracking state of charge without errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation calibration for the NS-15AT10:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% before using it again. The fuel gauge IC on this tablet calibrates against the cell it sees — skipping this step leaves it reading against the old cell's profile, which causes percentage jumps and early shutdowns.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNS-15AT10 shutting down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe NS-15AT10 draws a combined load from its display backlight, WiFi radio, and processor at the same time. Near the bottom of the discharge curve, cell voltage drops sharply under that combined load — faster than the fuel gauge expects. The BMS interprets this voltage cliff as a critically low state and cuts power before the displayed percentage reaches zero. Running one full discharge-to-shutoff cycle after installation recalibrates the fuel gauge IC to the new cell's actual discharge curve and brings the cutoff point back in line with what the screen shows.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or reading incorrectly after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the NS-15AT10 stores a learned discharge profile from the original cell. When a new cell goes in, the IC is still referencing old data — so it reports incorrect percentages, often jumping several points up or down as load changes. This is not a fault with the replacement cell; it is a calibration mismatch. Fix it by discharging the tablet completely to automatic shutoff, then charging uninterrupted to 100% — after one full cycle the IC resets its reference and percentage reporting stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425982775386,"sku":"BWCS-STA100SL-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425982808154,"sku":"BWCS-STA100SL-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425982840922,"sku":"BWCS-STA100SL-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-STA100SL-1.webp?v=1779930025","url":"https:\/\/batteryweb.com\/products\/insignia-flex-101-ns-15at10-replacement-battery-37v-7000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
