It replaces OEM part numbers P750BAT-8, 6-87-P750S-4272, 4ICR18\/65-2, and 6-87-P750S-4U73. Fit it when the original cell no longer holds a charge or the BIOS flags battery health as degraded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP750 \/ P770 platform compatibility:\u003c\/strong\u003e\n    These models share a common 14.8V four-cell rail, identical connector pinout, and the same BMS communication protocol — which is why one part number covers the full range. The replacement cell matches the original voltage and BMS handshake, so the BIOS recognises it without a firmware workaround.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on a P750-series unit. The BMS balanced all four cell groups correctly, the charge controller handed off cleanly at 16.8V, and the OS fuel gauge updated after two calibration cycles without throwing a health fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration on the P750ZM:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates on low battery, then charge uninterrupted to 100% before unplugging. This resets the BIOS battery learn cycle and clears the inaccurate health or \"unknown battery\" 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\"\u003eP750ZM shutting down at 20–30% remaining under gaming or CPU load\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe P750ZM pairs a high-TDP CPU with a discrete GPU, and under full load both can pull the pack voltage down sharply. When cell voltage drops below roughly 3.2V per cell under that load, the BMS triggers a protection cutoff — even if the OS fuel gauge still reads 25%. This is a voltage-cliff event, not a capacity fault. If it happens with a new cell, the BIOS fuel gauge IC hasn't completed its learn cycle yet and is misreporting state-of-charge. Run two full discharge-to-hibernate and charge-to-100% cycles; the cutoff point will shift back to the correct range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSystem information showing the wrong Wh rating after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWindows and the BIOS read Wh data from the battery's EEPROM, which stores the manufacturer's rated figure from the original cell. After a swap, the EEPROM on the new cell may report a slightly different value than what the old cell stored — this is normal when OEM and replacement cells use different internal ratings for the same chemistry. The actual usable capacity is 65.12Wh as listed. To clear the stale EEPROM reading from the OS, run a full discharge-to-hibernate cycle, recharge to 100%, then check Device Manager — the reported Wh figure should update to match the new cell's EEPROM data.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409749049434,"sku":"BWCS-CLP750NB-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409749082202,"sku":"BWCS-CLP750NB-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409749114970,"sku":"BWCS-CLP750NB-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLP750NB-1.webp?v=1779580646","url":"https:\/\/batteryweb.com\/products\/clevo-p750zm-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
