It replaces the OEM part AA-PBTN2TP directly. The slim 3.42mm cell profile matches the original pack geometry inside the 15.6-inch Chromebook chassis.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXE510C24 and XE510C25 compatibility:\u003c\/strong\u003e\n    Both the C24 and C25 variants share the same 7.6V two-cell Li-Polymer configuration, connector pinout, and BMS handshake protocol — which is why a single replacement covers the full XE510 line across both build revisions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Chromebook XE510 unit. The BMS handshake completed on first connection, charge current accepted normally from the OEM adapter, and the protection circuit triggered correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap learn cycle on ChromeOS:\u003c\/strong\u003e\n    After installing, let the Chromebook discharge fully until it hibernates on its own, then charge uninterrupted to 100% without using the device. This resets the fuel gauge IC against the new cell and clears the inaccurate battery health warning ChromeOS displays after every cell replacement.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy ChromeOS flags poor battery health immediately after replacing the XE510 cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eChromeOS reads battery health from EEPROM data stored on the original cell's BMS. When you swap in a new cell, the system compares the new cell's reported state-of-charge against the old EEPROM profile and flags a mismatch as degraded health. This is not a fault with the replacement cell. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% forces the fuel gauge IC to recalibrate against the new cell's actual capacity curve. After one or two full cycles, the health indicator normalises and reflects the new cell accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eXE510 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated to the new cell — the percentage displayed is based on the old cell's discharge curve, not the replacement's. Under full load (CPU burst plus display at full brightness), the new cell hits its actual low-voltage floor before the reported percentage reaches zero, and the BMS trips a protective shutdown. The fix is the same learn cycle: discharge to hibernate cutoff, then charge to 100% without interruption. After two full cycles the reported percentage and the actual cell voltage align, and early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409615683674,"sku":"BWCS-SMX510NB-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409615716442,"sku":"BWCS-SMX510NB-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409615749210,"sku":"BWCS-SMX510NB-3","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMX510NB-1.webp?v=1779580234","url":"https:\/\/batteryweb.com\/products\/samsung-xe510c25-k01us-replacement-battery-76v-5050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
