It matches OEM part number DBS-1350A and fits directly into the original battery compartment. Voltage and connector alignment match the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSmartEasy 7050 \/ 7050 Flip \/ 7070 \/ 7060 compatibility:\u003c\/strong\u003e\n    These models share the same 3.8V battery rail, physical footprint (53.54 × 38.30 × 5.56mm), and connector pinout. The BMS handshake protocol is consistent across the range, so one cell covers all listed variants 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 charge and discharge on the SmartEasy 7050 platform. The BMS accepted the cell without triggering fault codes, and the charge IC reached full termination voltage correctly at 4.35V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge-charge cycle at standard current. The fuel gauge IC on these Doro handsets calibrates its coulomb counter against the cell's actual discharge curve on the first cycle — skipping this step leads to inaccurate percentage readings until recalibration occurs naturally.\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 SmartEasy 7050 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's voltage-discharge curve. The new cell's voltage drops more steeply under modem or screen load than the old degraded cell did at the same reported percentage. The phone's power management circuit sees the voltage cliff and triggers an emergency shutdown before the gauge catches up. One full unconstrained discharge-charge cycle corrects the curve mapping and stops the premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If the cell voltage drops below 2.5V, the BMS enters lockout mode to prevent damage — the phone will show no response at all, not even a charging indicator. Connect the phone to a wall charger (not a USB port) and leave it untouched for 20–30 minutes. Most Doro SmartEasy BMS circuits will re-initialise once the cell recovers to approximately 3.0V, at which point the charging animation should appear.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391897829466,"sku":"BWCS-DEP705SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391897862234,"sku":"BWCS-DEP705SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391897895002,"sku":"BWCS-DEP705SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEP705SL-1.webp?v=1779142596","url":"https:\/\/batteryweb.com\/products\/doro-smarteasy-7050-replacement-battery-38v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
