It replaces OEM part numbers KM973, KM974, KM978, MT335, MT342, PW823, PW824, PW835, RM791, RM868, RM870, 312-0711, 312-0712, and 312-0708. The cell fits the three-cell bay on these 17-inch Studio notebooks and communicates directly with the Dell EC over SMBus.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStudio 1735, 1736, and 1737 fitment:\u003c\/strong\u003e\n    All three models share the same battery bay geometry, connector pinout, and SMBus communication protocol. The Dell embedded controller expects the same voltage rail and BMS handshake across this generation, so one cell covers all three chassis.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Studio 1735 unit and confirmed the BMS reported capacity within normal range on first charge. The EC accepted the SMBus data without triggering an unknown device flag on initial power-on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on Studio notebooks:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health 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\"\u003eWhy the Studio 1735 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Studio 1735 uses a fuel gauge IC that stores charge-curve data from the previous cell in non-volatile memory. When a new cell goes in, that stored curve no longer matches the actual chemistry, so the IC miscalculates remaining charge. Under full CPU plus display load, the real cell voltage drops faster than the IC predicts, triggering an emergency shutdown before the displayed percentage hits zero. Running two to three full discharge-to-hibernate and full-recharge cycles forces the IC to rebuild its curve against the new cell and stops the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reports wrong Wh rating after installing this cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dell BIOS reads Wh rating from the battery's EEPROM, not by measuring the cell directly. Replacement cells carry EEPROM values written at the factory, and minor differences between rated and measured chemistry can produce a Wh figure that does not match the label. This is a data mismatch between EEPROM fields, not a capacity fault. Check the actual charge level percentage rather than the Wh readout — if the cell is charging and discharging normally, the EEPROM figure can be disregarded.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410811420762,"sku":"BWCS-DE1735HB-1","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410811453530,"sku":"BWCS-DE1735HB-2","price":145.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410811486298,"sku":"BWCS-DE1735HB-3","price":158.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE1735HB-1.webp?v=1779581142","url":"https:\/\/batteryweb.com\/products\/dell-studio-1735-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
