It fits both variants of the N20 line and matches the OEM voltage and capacity specification. The part numbers 865Y032 and BT-12416 cross-reference to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN20 and N20w fit:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, voltage rail, and connector pinout, so one cell covers both variants without modification.\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 the N20 platform and confirmed the BMS accepted full charge without triggering a protection cutoff under normal PDA load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-swap sync:\u003c\/strong\u003e\n    The N20 stores open application state and unsaved data in RAM powered directly by the main battery. Sync all data to your host computer before removing the old cell — RAM contents are lost the moment power drops.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the N20 fails to boot after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe N20 boot sequence checks for a minimum voltage threshold before the processor initialises. A new cell shipped in storage state may sit below that threshold, which causes the device to appear dead even though the hardware is functional. Connecting to a charger for at least 30 minutes before pressing the power button is enough to bring the cell above the boot threshold. Do not interpret a blank screen immediately after swap as a faulty battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWireless sync dropping or slowing after a battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe N20's wireless radio is voltage-sensitive and draws a short current spike when transmitting. If the battery is not fully charged, that spike can pull cell voltage low enough to trigger the BMS under-voltage protection, causing the radio to drop mid-session. Charge the battery to full — approximately 4.2V at the cell — before attempting ActiveSync or Bluetooth pairing. A partial charge that looks sufficient for standby use often isn't enough to sustain the radio under transmission load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415946428506,"sku":"BWCS-N20SL-1","price":37.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43415946461274,"sku":"BWCS-N20SL-2","price":43.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43415946494042,"sku":"BWCS-N20SL-3","price":47.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-N20SL-big.webp?v=1779758396","url":"https:\/\/batteryweb.com\/products\/acer-n20-replacement-battery-37v-1300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
