It replaces OEM part number C105440270P. Fit the new cell when the original no longer holds a charge or shuts down unexpectedly under load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD950 series compatibility:\u003c\/strong\u003e\n    The D950, D950U, and D950L share the same battery bay dimensions, connector pinout, and BMS handshake protocol. All three accept this 101.90 × 53.90 × 3.80mm 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 on a D950 unit and confirmed the BMS accepted charge immediately, with no false full-charge cutoff on the first cycle. Voltage held steady at 3.7V nominal across a full discharge sweep.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging for your first complete discharge-charge cycle after installation. This allows the fuel gauge IC to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the D950 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a different internal resistance profile than the worn cell the fuel gauge IC was calibrated against. Under modem or display load, current draw spikes and the cell voltage drops sharply — faster than the gauge expects. The IC interprets this as a depleted cell and triggers a protection shutdown, even though the reported percentage still shows charge remaining. One full discharge-charge cycle without fast charging resets the coulomb counter and eliminates these early shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after fitting the replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the D950 stores a learned discharge curve from the original cell. A new cell with different impedance characteristics makes the reported percentage drift — often reading 15–20% higher than actual state of charge. This is not a fault with the replacement cell. Drain the battery to automatic shutdown, then charge uninterrupted to 100% without removing the cable early. After one full cycle, the coulomb counter re-anchors to the new cell curve and percentage accuracy stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392096731226,"sku":"BWCS-BLD950SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392096763994,"sku":"BWCS-BLD950SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392096796762,"sku":"BWCS-BLD950SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLD950SL-1.webp?v=1779143748","url":"https:\/\/batteryweb.com\/products\/blu-dash-x-plus-replacement-battery-37v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
