It uses OEM part numbers PA70BAT-4 and 6-87-PA70S-61B00. Compatible models include the PA71HS, PA71HS-G, PA70HP6-G, and PA71HP6-G.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePA70\/PA71 platform fitment:\u003c\/strong\u003e\n    These models share the same 15V four-cell battery architecture, connector pinout, and BMS communication protocol — meaning one cell works across the range without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a PA71 platform and confirmed the BMS handshake completed cleanly, charge acceptance reached full capacity, and no mid-cycle cutoff events were recorded under sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the PA71HS:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge 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 the PA71HS shuts down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS fuel gauge IC builds a discharge model based on the previous cell's internal resistance curve. A new lithium-polymer cell has a different voltage-to-capacity curve, so the gauge misreads the cutoff point and signals shutdown before the cell is actually empty. This shows up as abrupt shutdowns at 20–30% on the first few cycles. Running two or three full discharge-to-hibernate and uninterrupted-recharge cycles teaches the fuel gauge IC the new cell's actual voltage floor, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS showing battery health as \"poor\" or capacity as 0% immediately after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads health data from the cell's EEPROM, which still holds the degraded metrics of the old battery during the first boot. This is not a fault with the replacement cell — it is a stale data read. Boot into the BIOS battery information screen and confirm voltage is present at the expected 15V nominal. Then run a full discharge-to-hibernate cycle followed by a full uninterrupted charge; the BIOS learn cycle will overwrite the old EEPROM health values and report correct capacity on the next boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409594253402,"sku":"BWCS-CLA710NB-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409594286170,"sku":"BWCS-CLA710NB-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409594318938,"sku":"BWCS-CLA710NB-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLA710NB-1.webp?v=1779580128","url":"https:\/\/batteryweb.com\/products\/clevo-pa71hs-replacement-battery-15v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
