It replaces OEM part numbers ELF0160, 35H00095-00M, and FFEA175B009951. Install it when the original cell no longer holds voltage under screen or modem load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMP6900 and Vogue platform fit:\u003c\/strong\u003e\n    Both devices share the same battery bay dimensions (51.53 × 37.36 × 5.35mm), connector pinout, and charge IC handshake — one cell fits both 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 MP6900 platform. The BMS accepted charge current without tripping, and voltage held stable through simulated screen-on and modem-active draw states.\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-to-charge cycle. The fuel gauge IC on these phones calibrates its coulomb counter against the cell's discharge curve — skipping this step causes the OS to report inaccurate percentages from day one.\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 MP6900 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still mapped to the old cell's voltage curve. The new cell hits a voltage cliff under modem or display load earlier than the gauge predicts, so the phone cuts power before the displayed percentage reaches zero. It is not a defective battery — it is a calibration mismatch. Run one full discharge from 100% down to automatic shutdown, then charge uninterrupted to 100%, and the coulomb counter resets to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone feels warm near the battery compartment on the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell has higher internal impedance than a worn one. The charge IC pushes the same current profile it used on the degraded original, and higher impedance means more energy is lost as heat in the cell during those first cycles. This is normal and typically resolves after two to three full charge cycles as the cell's impedance settles. If warmth continues past the third full charge, check that the back cover is seated correctly — trapped air blocks heat dissipation and amplifies the effect.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405251248218,"sku":"BWCS-DTS1SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405251280986,"sku":"BWCS-DTS1SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405251313754,"sku":"BWCS-DTS1SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DTS1SL-1.webp?v=1779370350","url":"https:\/\/batteryweb.com\/products\/utstarcom-mp6900-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
