It fits the Satellite 1750, 1755CE, and 1730 series laptops that share the PA3055U battery platform. Install replaces a dead or capacity-depleted original cell without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSatellite 1730 series platform fit:\u003c\/strong\u003e\n    The 1730CDT, 1750, and 1755CE share the same 9.6V battery bay geometry and PA3055U connector pinout. The BMS handshake expects a Ni-MH cell at this voltage rail — swapping in a different chemistry triggers a charge fault. This cell matches that spec exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Satellite 1730-series unit. The BMS accepted the cell without fault, charge current ramped correctly to full, and the delta-peak cutoff terminated the charge cycle as expected at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH recalibration after install:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to the laptop's hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a 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 battery health as poor after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Satellite 1730 BIOS stores learned capacity data from the previous cell in firmware. When a new cell goes in, that stored data no longer matches actual cell behaviour, so the BIOS flags poor health even though the new cell is fine. Running one full discharge-to-hibernate followed by a complete uninterrupted charge forces the BIOS to rewrite its battery learn table against the new cell. After one or two cycles the health indicator clears and the fuel gauge reads accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop cutting off at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot sustain voltage under the combined load of the CPU and display at low state of charge — the voltage drops below the BMS cutoff threshold before the fuel gauge reaches zero. On a degraded original cell this is a chemistry failure, not a firmware issue. On a fresh replacement cell it usually means the fuel gauge IC has not yet calibrated to the new cell's discharge curve. Run two full discharge-to-hibernate cycles and watch whether the cutoff point shifts down toward 10% or lower — if it does, calibration is working. If it persists below 15% shown, check AC adapter output is stable at 15V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410870239322,"sku":"BWCS-TO1700NB-1","price":70.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410870272090,"sku":"BWCS-TO1700NB-2","price":83.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410870304858,"sku":"BWCS-TO1700NB-3","price":92.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TO1700NB-big.webp?v=1779581402","url":"https:\/\/batteryweb.com\/products\/toshiba-satellite-1730cdt-replacement-battery-96v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
