It fits the XQ700T1C, XE700T1C, XQ700T1C-A52, and over 24 additional Ativ Pro variants. Capacity is 6540mAh (49.05Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAtiv Pro XQ700T1C and XE700T1C compatibility:\u003c\/strong\u003e\n    These models share the same 7.5V power rail, slim 6.24mm cell profile, and AA-PLZN4NP connector pinout. The BMS handshake is identical across the range, so one cell serves the full series without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, load, and BMS communication checks on the XQ700T1C platform. The BMS accepted the cell, reported voltage correctly, and charge termination triggered at the expected threshold with no error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Ativ Pro:\u003c\/strong\u003e\n    After fitting, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false poor-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\"\u003eBIOS reporting poor battery health immediately after fitting the AA-PLZN4NP replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ativ Pro BIOS reads health data from EEPROM stored on the original cell. When a new cell arrives, that EEPROM data does not match the fresh chemistry, so the BIOS flags poor health before any real degradation has occurred. This is not a fault with the replacement cell — it is a calibration gap. Run one full discharge-to-hibernate cycle followed by an uninterrupted full charge. After two to three cycles the BIOS learn routine updates its baseline and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAtiv Pro shutting down abruptly while the gauge still shows 20–30% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. Under combined CPU and display load the voltage drops faster than the uncalibrated gauge predicts, and the BMS triggers a hard cutoff before the displayed percentage reaches zero. It is not a defective cell — it is a mismatch between the stored curve and the new chemistry. Force two complete discharge-to-hibernate cycles with no interruption, then charge fully each time. After those cycles the fuel gauge IC recalculates its curve and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409789419610,"sku":"BWCS-SXE700NB-1","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409789452378,"sku":"BWCS-SXE700NB-2","price":145.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409789485146,"sku":"BWCS-SXE700NB-3","price":158.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SXE700NB-1.webp?v=1779580888","url":"https:\/\/batteryweb.com\/products\/samsung-ativ-pro-replacement-battery-75v-6540mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
