It replaces OEM part C776043250T when the original cell has degraded, swollen, or lost the ability to hold a charge under normal use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD0010U \/ D0010UU \/ Bold LIKS US compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The 77.15 × 59.95 × 4.20mm cell fits each variant 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 full charge and discharge on the D0010U. The BMS accepted charge negotiation on the first connection, and voltage held stable across screen-on and modem-active load states without triggering a low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter to the new cell's actual discharge curve before any high-current session pushes charge 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 Dash X LTE\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dash X LTE's modem and display together create short, high-current draw spikes. An aged or uncalibrated cell cannot sustain voltage under this combined load even when the OS reports charge remaining. The voltage drops below the BMS cutoff threshold, and the phone shuts off. The fix is a full discharge-to-shutdown cycle followed by an uninterrupted charge to 100% — this re-anchors the fuel gauge IC's endpoints to the new cell's actual voltage floor and ceiling.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after the cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores a charge curve calibrated to the old cell. When a new cell goes in, the stored curve no longer matches actual cell chemistry, so the percentage readout drifts or jumps. This is not a faulty battery — it is the IC recalibrating. Run the phone from 100% down to automatic shutdown, then charge to 100% without interruption. After that single cycle, the coulomb counter resets to the new cell's real capacity and percentage reporting stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392096632922,"sku":"BWCS-BLD010SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392096665690,"sku":"BWCS-BLD010SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392096698458,"sku":"BWCS-BLD010SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLD010SL-1.webp?v=1779143748","url":"https:\/\/batteryweb.com\/products\/blu-dash-x-lte-d0010u-replacement-battery-38v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
