It matches OEM part numbers ELF0160, 35H00095-00M, and FFEA175B009951. If the original battery no longer holds charge through a normal day of calls and screen use, this cell swaps directly into the same bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMDA Touch battery platform:\u003c\/strong\u003e\n    The MDA Touch uses a slim 3.7V single-cell pack sized at 51.53 × 37.36 × 5.35mm. The connector pinout and BMS handshake match the original spec — the phone's charge IC communicates with the pack over the same lines as the factory cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the MDA Touch platform. The BMS accepted the charge IC handshake on the first cycle, and charge termination triggered correctly at full voltage without overrun.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to near-empty before recharging. The MDA Touch fuel gauge IC holds the old cell's discharge curve in memory — one complete cycle overwrites it and stops the percentage counter from reading against stale data.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MDA Touch shuts down suddenly at 20–30% after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MDA Touch fuel gauge IC was calibrated against the original cell's internal resistance profile. A new cell has a different discharge curve, so the IC underestimates remaining capacity and triggers a low-voltage shutdown before the percentage counter reaches zero. Under modem or screen load, the voltage drop on a fresh cell is steeper than the IC expects. One full discharge-charge cycle lets the coulomb counter relearn the curve and align the reported percentage with actual cell voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the pack dropped below approximately 2.5V, the BMS enters lockout mode to prevent damage — the phone will show no response when you press the power button. Connect the MDA Touch to a wall charger, not a USB port, and leave it for 20–30 minutes before attempting to power on. A wall adapter delivers enough current to push the cell back above the BMS recovery threshold, typically around 2.9V, at which point the BMS releases and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405254328410,"sku":"BWCS-DTS1SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405254361178,"sku":"BWCS-DTS1SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405254393946,"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\/t-mobile-mda-touch-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
