It slots in where the original A31-JN101 cell sits and restores portable power to the machine. If your current battery no longer holds a charge or the system shuts off unexpectedly, this is the correct replacement cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eJN101 netbook compatibility:\u003c\/strong\u003e\n    The JN101 runs a low-voltage Atom-class platform that draws a consistent current profile. The A31-JN101 part number maps directly to the connector pinout and BMS handshake voltage range this platform expects — no adapters or modifications needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and discharge cycle on the bench. The BMS responded correctly at both ends — charge termination triggered cleanly at 12.6V and the low-voltage cutoff held at the expected floor without tripping prematurely under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration on the JN101:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the system hibernates on its own, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the JN101 BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe JN101 stores battery health data in EEPROM on the original cell. When a new cell goes in, the BIOS reads no matching historical data and defaults to a poor health or unknown status flag. This is not a fault with the replacement cell — it is the BIOS reacting to a blank slate. Running one complete learn cycle (full discharge to hibernate cutoff, then uninterrupted charge to 100%) writes fresh calibration data and clears the flag. After two to three cycles the reported health figure stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFuel gauge jumping erratically in the first few cycles after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the JN101 estimates state-of-charge by tracking voltage curves it learned from the old cell. A new cell has a slightly different discharge curve, so the gauge reads inaccurately — jumping from 60% to 20% or stalling at a fixed number. This is a calibration gap, not a faulty battery. Run two or three full charge-discharge cycles and the IC relearns the curve against the new cell. By the third cycle the gauge should track within a few percent of actual capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409748066394,"sku":"BWCS-AUN101NB-1","price":74.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409748099162,"sku":"BWCS-AUN101NB-2","price":87.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409748131930,"sku":"BWCS-AUN101NB-3","price":97.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUN101NB-1.webp?v=1779580647","url":"https:\/\/batteryweb.com\/products\/asus-jn101-replacement-battery-108v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
