It slots directly into either device and communicates with the onboard BMS using the same handshake as the OEM cell. Capacity is 2200mAh (16.28Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eToughbook 01 and CF-P1 compatibility:\u003c\/strong\u003e\n    Both models run on the same 7.4V power rail and share the CF-VZSU22 connector and BMS protocol. One cell serves both platforms without hardware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the CF-P1 platform. The BMS accepted the cell on first connection, reported state of charge accurately, and held voltage above 6.8V through a full discharge cycle with the wireless radio active.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRAM and data state before removal:\u003c\/strong\u003e\n    Perform a full sync to your host PC before pulling this battery. The Toughbook CF-P1 holds open application state and unsaved data in volatile RAM powered by the main battery. A full power loss clears that memory entirely.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRugged handheld not booting after new battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly shipped Li-ion cell typically arrives at 40–60% charge. The CF-P1 boot sequence draws a short current spike that can trip the BMS undervoltage cutoff if the cell is too depleted. The device shows nothing on screen — no logo, no boot progress — and appears dead. Charge the battery to at least 7.2V before attempting the first boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or reading incorrectly after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CF-P1 tracks state of charge through a fuel gauge that calibrates against the previous battery's discharge history. Swapping in a new cell can cause the gauge to report incorrect percentages — sometimes jumping from 80% to 20% with no load applied. Run one full charge to 100% followed by a complete discharge to let the gauge re-calibrate. After one full cycle, readings stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415942398042,"sku":"BWCS-VZ22XL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415942430810,"sku":"BWCS-VZ22XL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415942463578,"sku":"BWCS-VZ22XL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VZ22XL-1.webp?v=1777949432","url":"https:\/\/batteryweb.com\/products\/panasonic-tunghbook-01-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
