It restores portable power to a laptop that no longer holds charge or fails to run off-mains. Capacity is 47.52Wh, matching the stock specification for this platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSatellite L700 \/ L700D platform fit:\u003c\/strong\u003e\n    These models share the same 10.8V battery bay, connector pinout, and BMS handshake protocol across the series. One cell covers L700, L700D, L700-T10R, L700-T11B, and over 300 additional Satellite variants that draw from the same power rail.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the L700 platform and confirmed the BMS negotiated correctly with the BIOS, accepted a full charge cycle without thermal event, and reported state-of-charge accurately after two calibration passes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on L700D:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate cutoff, 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 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\"\u003eBIOS reporting poor battery health immediately after fitting the new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eToshiba's BIOS reads health data stored in the battery's EEPROM and compares it against historical charge data from the old cell. When a new cell arrives, that EEPROM data does not match the BIOS log, so the firmware flags it as degraded. This is not a fault with the replacement cell. Run a full discharge-to-hibernate then an uninterrupted charge to 100% and the BIOS will re-learn the cell's actual capacity. After one complete learn cycle, the health indicator clears on most L700 series units.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts off abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The OS reads remaining charge from a table built on the old cell's behaviour, so it underestimates how fast voltage drops under combined CPU and display load. When actual cell voltage hits the hardware cutoff threshold, the laptop powers off even though the gauge still shows charge remaining. Run two full discharge-to-hibernate cycles followed by full charges to let the fuel gauge IC rebuild its estimate — the shutoff point will move back toward 0% once calibration completes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410739396698,"sku":"BWCS-TOL700NB-1","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410739429466,"sku":"BWCS-TOL700NB-2","price":117.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410739462234,"sku":"BWCS-TOL700NB-3","price":128.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TOL700NB-1.webp?v=1779581059","url":"https:\/\/batteryweb.com\/products\/toshiba-satellite-l700d-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
