It cross-references OEM part numbers 5B10W51893, L21C6P70, L21D6P70, L21L6P70, L21M6P70, and SB10W51994. Fits the P16 Gen1 2022 mobile workstation directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThinkPad P16 Gen1 compatibility:\u003c\/strong\u003e\n    All P16 Gen1 variants share the same 11.52V six-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol — so one part number covers the full Gen1 build range including the 00CD configuration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a ThinkPad P16 Gen1 under sustained CPU and GPU load. The BMS held steady across full charge-discharge cycles, with no unexpected cutoff events at any state of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration for the P16 workstation:\u003c\/strong\u003e\n    After fitting a new cell, run the laptop down to hibernate-cutoff under normal workstation load, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.\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 new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ThinkPad BIOS reads health data from the battery's EEPROM — not from live cell measurements. When you fit a new cell, the EEPROM still reflects the degraded state recorded by the old pack. The system flags poor health because it hasn't yet run a learn cycle against the new chemistry. One full discharge to hibernate followed by an uninterrupted charge to 100% rewrites that data. After that cycle completes, the BIOS health indicator should update correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eThinkPad P16 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 hasn't calibrated its discharge curve against the new cell. The gauge predicts voltage behaviour based on the old cell's profile, so it misreads remaining capacity under load. When the CPU and dGPU both spike simultaneously, the real cell voltage drops below the BMS cutoff threshold while the gauge still shows 20–30%. Run two to three full discharge-to-hibernate and full-recharge cycles. By the third cycle the fuel gauge IC should track the new cell accurately and the premature shutdowns will stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409544347738,"sku":"BWCS-LVP160NB-1","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409544380506,"sku":"BWCS-LVP160NB-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409544413274,"sku":"BWCS-LVP160NB-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVP160NB-1.webp?v=1779579986","url":"https:\/\/batteryweb.com\/products\/lenovo-thinkpad-p16-00cd-2022-replacement-battery-1152v-7950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
