It replaces OEM part numbers BAT-30IL, F1450-80002, F1450-80004, and F1450A. If your original cell no longer holds charge or the system refuses to leave AC power, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOmnibook 7100 and 7150 compatibility:\u003c\/strong\u003e\n    Both models share the same 14.4V battery bay, connector pinout, and BMS handshake protocol — one cell fits both. The battery management system uses the same EEPROM data structure across the 7100 and 7150 production runs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full load discharge, and BMS cutoff on Omnibook-class hardware. The protection circuit responded correctly at both overvoltage and undervoltage thresholds, and the EEPROM flags cleared as expected after a full learn cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Omnibook:\u003c\/strong\u003e\n    After installing, run one complete discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears immediately 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 Omnibook 7100 reports poor battery health right after a new cell install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Omnibook's BIOS reads health status from EEPROM data written by the original cell's fuel gauge IC. A new cell arrives with factory EEPROM values that don't match your system's charge history, so the BIOS flags it as degraded immediately. This is a data mismatch, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 14.4V allows the fuel gauge IC to rewrite the EEPROM with accurate cycle data for your unit.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOmnibook shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under full CPU and display load before the OS fuel gauge reaches zero. The fuel gauge IC is still reporting 20–30% remaining, but the actual cell voltage has already hit the cliff — typically around 12.0–12.5V under load on a 14.4V nominal pack. The gauge and the real charge state have drifted apart after years of shallow cycling on the original cell. Run two full discharge-to-cutoff and full recharge cycles on the new cell to resync the fuel gauge IC against the new cell's actual capacity curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410876039258,"sku":"BWCS-DE7500NB-1","price":90.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410876072026,"sku":"BWCS-DE7500NB-2","price":106.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410876104794,"sku":"BWCS-DE7500NB-3","price":119.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE7500NB-big.webp?v=1779581442","url":"https:\/\/batteryweb.com\/products\/hp-omnibook-7100-replacement-battery-144v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
