It also fits the Chromebook 11.6 variants sharing the same connector and voltage rail. The cell matches OEM dimensions at 250.52 x 153.50 x 3.90mm for a direct fit into the original bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN20 and N20P compatibility:\u003c\/strong\u003e\n    The N20 and N20P share the same 11.1V three-cell Li-Polymer architecture, battery connector pinout, and BMS handshake protocol. Both accept part numbers L13L3P61 and L13M6P61 without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an N20P unit under Chrome OS load. The BMS negotiated charge termination correctly, and the fuel gauge IC responded to the new cell without tripping any protection cutoffs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration for the N20P:\u003c\/strong\u003e\n    After installing this cell, run the Chromebook down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Chrome OS reports poor battery health after replacing the N20P cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Chromebook's EC firmware stores capacity and cycle data in the old cell's EEPROM. When a new cell goes in, that stored data no longer matches the physical chemistry. Chrome OS reads the mismatch and flags the battery as degraded. This is not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the learn cycle and rewrites the EC's reference data to match the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eN20P shutting down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated against the old cell's discharge curve. The percentage shown no longer corresponds to actual cell voltage, so the system hits the low-voltage cutoff while the gauge still reads 20–30%. The fix is a full calibration cycle: discharge to automatic hibernate, then charge to 100% without interruption. After two to three full cycles, the fuel gauge IC re-maps its reference curve and the reported percentage tracks actual cell voltage accurately again — check that the gauge reads below 3.4V per cell at hibernate before assuming the cell is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409763172442,"sku":"BWCS-LVN200NB-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409763205210,"sku":"BWCS-LVN200NB-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409763237978,"sku":"BWCS-LVN200NB-3","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVN200NB-1.webp?v=1779580734","url":"https:\/\/batteryweb.com\/products\/lenovo-chromebook-n20p-replacement-battery-111v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
