It matches the original cell format, connector, and BMS communication spec for these notebooks. OEM part numbers covered include PA5076R-1BRS, PA5076U-1BRS, PA5077U-1BRS, PABAS268, and PABAS269.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSatellite L900 and L950 series fit:\u003c\/strong\u003e\n    These models share the same 14.8V four-cell Li-ion architecture, identical battery bay dimensions, and the same SMBUS handshake protocol — which is why one cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on Satellite L950 hardware. The BMS completed a full charge sweep without interruption, and the protection circuit tripped correctly at the low-voltage floor — no spurious cutoffs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after install:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff on battery alone, then charge uninterrupted to 100%. This clears the BIOS battery learn cycle and resets the fuel gauge IC against the new cell's actual capacity — skipping it causes the health warning that shows up after most cell swaps.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Satellite L900 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Satellite L900's BIOS tracks battery state using stored discharge curves from the previous cell. When a new cell goes in, those curves no longer match the actual voltage profile of the replacement. Under full CPU and display load, the laptop hits a voltage drop the BIOS interprets as empty — even though the fuel gauge still reads 20–30%. Running two full discharge-to-hibernate and uninterrupted charge cycles recalibrates the fuel gauge IC and clears the mismatch. After calibration, the cutoff point aligns with actual cell depletion around 14.4–14.6V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" or \"replace\" immediately after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Satellite's BIOS reads health data from the battery's EEPROM, which on a new replacement cell defaults to a conservative factory-state value — not a degraded reading. The BIOS compares this against its own tracked cycle history from the old battery and flags a mismatch as poor health. This is not a fault with the replacement cell. Run the full discharge-to-hibernate cycle once, then charge to 100% without interruption, and the BIOS will rewrite its baseline — the warning clears on the next boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409787125850,"sku":"BWCS-TOL900NB-1","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409787158618,"sku":"BWCS-TOL900NB-2","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409787191386,"sku":"BWCS-TOL900NB-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TOL900NB-1.webp?v=1779580888","url":"https:\/\/batteryweb.com\/products\/toshiba-satellite-l900-replacement-battery-148v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
