It fits directly in place of OEM part numbers DR35 and DR35S. Use it when the original cell no longer holds a charge or the laptop fails to power on from battery.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eModel 3000S fit:\u003c\/strong\u003e\n    The DR35 and DR35S share the same connector pinout, voltage rail, and BMS handshake protocol on the Model 3000S. Both OEM numbers cross to this cell 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, load, and discharge on the Model 3000S platform. The BMS accepted the cell, reported state-of-charge correctly after two calibration cycles, and held voltage under sustained CPU and display load without triggering a low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on the Model 3000S:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health or unknown-battery warning that typically 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 health or unknown battery after fitting the DR35\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you swap a Ni-MH cell, the BIOS reads EEPROM data left over from the old battery. The health flag it raises reflects the previous cell's recorded state, not the new one. The Model 3000S does not automatically clear this flag on first boot. Run one full discharge to hibernate, then a full uninterrupted charge — the BIOS learn cycle rewrites the EEPROM baseline against the new cell and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eModel 3000S shuts down at 20–30% battery shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a capacity fault. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track, and the BIOS hits its low-voltage cutoff before the displayed percentage reaches zero. The fuel gauge IC needs two or three full calibration cycles against the new cell to map the discharge curve accurately. Complete two full discharge-to-hibernate and charge-to-100% cycles — after that, the gauge and the actual cutoff voltage align and the early shutdown stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410860408922,"sku":"BWCS-DR35HB-1","price":84.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410860441690,"sku":"BWCS-DR35HB-2","price":100.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410860474458,"sku":"BWCS-DR35HB-3","price":111.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DR35HB-big.webp?v=1779581376","url":"https:\/\/batteryweb.com\/products\/techmedia-model-3000s-replacement-battery-108v-4000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
