These are senior-focused mobile phones that rely on emergency calling and simplified voice functionality. Correct voltage and capacity come from the product data — 3.7V, 1050mAh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePhoneEasy 326 series compatibility:\u003c\/strong\u003e\n    The 326, 326GSM, 328, and HandlePlus 326i share the same battery bay dimensions (72.68 × 43.86 × 5.18mm), voltage rail, and connector orientation. All four accept the same OEM part references — EASYUSE 3.7\/700, DBK-700, and XWD081206UL00459.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full discharge-to-charge sequence and confirmed the BMS communicates correctly with the charge IC. The protection circuit trips appropriately at low-voltage cutoff and releases cleanly on reconnection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After fitting this battery, run the phone down to auto-shutdown once before charging it back to 100%. The fuel gauge IC is still calibrated to the old cell's discharge curve — one full cycle resets the coulomb counter reference so percentage readings track accurately.\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 Doro PhoneEasy 326\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC reports a percentage based on the degraded original cell's curve, but the new cell has a different discharge profile. The phone's power management reads 25% remaining while the actual cell voltage has already dropped below the modem's minimum operating threshold. Under the brief current spike of a call or network search, voltage sags just enough to trigger emergency shutdown. One full discharge-charge cycle corrects the IC's reference and stops false cutoffs.\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 during storage. If the cell drops below approximately 2.5V, the BMS latches into lockout mode to prevent damage — the phone will show no response at all, not even a charge indicator. Connect the phone to a wall charger (not a USB port) and leave it untouched for 20–30 minutes. The charge IC trickle-charges the cell at low current until voltage climbs above the BMS re-enable threshold, typically around 2.9V, at which point normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405072629850,"sku":"BWCS-DEP326SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405072662618,"sku":"BWCS-DEP326SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405072695386,"sku":"BWCS-DEP326SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEP326SL-1.webp?v=1779369918","url":"https:\/\/batteryweb.com\/products\/doro-phoneeasy-326-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
