It replaces OEM part numbers PH26B and AHTXDSSN. Fit the original cell failing to hold a charge or showing erratic capacity behaviour.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDopod 700 fit:\u003c\/strong\u003e\n    The 700 uses a dedicated battery bay with a specific connector pinout and BMS handshake. This cell matches the 3.7V nominal voltage rail and physical dimensions (84.78 × 58.32 × 11.68mm) the phone's charge IC expects.\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 bench. The BMS engaged protection correctly at both ends of the voltage curve, and charge termination triggered cleanly without overrun.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, disable fast charging for one complete discharge-charge cycle. The Dopod 700's fuel gauge IC is calibrated to the old cell's discharge curve. Running one slow cycle lets it re-map against the new cell before high-current charging pushes amps into an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Dopod 700 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dopod 700 tracks charge state using a fuel gauge IC that builds a model of the cell's discharge curve over time. When you swap in a new cell, the IC still references the old model. This mismatch causes the displayed percentage to read high or low against actual cell voltage. One full slow discharge to shutdown — then a full charge — rewrites the curve and restores accurate reporting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the modem or display draws a short current spike and the cell voltage drops below the BMS cutoff threshold before the fuel gauge has recalibrated. The phone reads 25% but the actual cell voltage collapses under load to below 3.2V, triggering a hard shutdown. It is not a defective cell — it is a calibration lag. Run a full discharge to zero, let the phone shut off naturally, then charge uninterrupted to 100% at standard current to reset the reference point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409439129690,"sku":"BWCS-PH26BDL-1","price":40.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409439162458,"sku":"BWCS-PH26BDL-2","price":46.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409439195226,"sku":"BWCS-PH26BDL-3","price":51.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PH26BDL-big.webp?v=1779579689","url":"https:\/\/batteryweb.com\/products\/dopod-700-replacement-battery-37v-4200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
