It matches the OEM voltage, capacity, and connector footprint for the DuraForce Pro 2 platform. Dimensions are 83.90 × 55.20 × 5.20mm — confirm against your original before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE6910 and E6920 platform fit:\u003c\/strong\u003e\n    Both the E6910 and E6920 share the same battery bay geometry, voltage rail, and BMS handshake protocol — one cell covers both variants without any modification to the connector or flex cable routing.\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 a DuraForce Pro 2 unit. The BMS accepted the cell, the charge IC negotiated correctly, and the protection circuit triggered at expected cutoff thresholds with no false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge recalibration:\u003c\/strong\u003e\n    After installation, disable fast charging and run one full discharge-to-charge cycle at standard rate. The fuel gauge IC is still calibrated to the old cell's discharge curve — skipping this step causes the OS to misread state-of-charge on the new cell until the coulomb counter resets.\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 DuraForce Pro 2 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DuraForce Pro 2's modem and display draw significant current spikes during active use. A new cell with an uncalibrated fuel gauge IC causes the OS to misread the remaining charge state. When actual cell voltage drops below the BMS protection threshold under load — typically around 3.4–3.5V — the phone shuts down even though the percentage display still reads 20–30%. One full slow-charge discharge cycle lets the coulomb counter map the new cell's actual discharge curve and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDuraForce Pro 2 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-polymer cells self-discharge during storage. If voltage drops below 2.5V per cell, the BMS enters lockout mode and blocks current flow entirely — the phone shows nothing on screen and does not respond to the power button. Connect the device to a wall charger (not a PC USB port) and leave it for 15–20 minutes without pressing anything. The charge IC applies a low-current trickle to bring the cell above the BMS recovery threshold, typically around 2.9V, at which point normal charging resumes and the phone powers on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391852511322,"sku":"BWCS-KYE691SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391852544090,"sku":"BWCS-KYE691SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391852576858,"sku":"BWCS-KYE691SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KYE691SL-1.webp?v=1779142367","url":"https:\/\/batteryweb.com\/products\/kyocera-duraforce-pro-2-replacement-battery-38v-3150mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
