It matches the OEM part number Li3925T44P8h786035 and fits the physical cavity at 76.80 x 59.60 x 3.20mm. Use this when the original cell no longer holds charge through a normal day of calls, messaging, and app use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade A910 platform fit:\u003c\/strong\u003e\n    The A910, A910 Dual, and A910 Dual SIM all share the same battery bay dimensions, connector pinout, and BMS handshake — one cell covers the full variant range without modification.\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 a Blade A910 unit. The BMS accepted the cell without fault flags, the charge IC reached full termination voltage correctly, and the protection circuit tripped at the expected over-discharge threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC build an accurate discharge curve for the new cell before high-current charging begins. Skipping this step is the main reason users see erratic percentage readings in the first few days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Blade A910 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Blade A910 uses a coulomb counter and stored discharge curve to estimate remaining charge. When you install a new cell, the fuel gauge IC is still calibrated to the old, degraded cell's curve. The result is that the percentage display may jump, stall, or plateau at values that do not reflect actual charge state. One full discharge to auto-off followed by an uninterrupted charge to 100% resets the reference points and brings the displayed percentage back in line with real capacity.\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 radio, screen, or a background app pulls a current spike the cell cannot sustain without voltage dropping below the BMS cutoff threshold — even though the gauge still shows charge remaining. It is a calibration gap, not a faulty cell. The protection circuit cuts power at roughly 3.0V per cell to prevent damage, and the OS interprets that as a shutdown. Run the full recalibration cycle described above; after one complete discharge-charge pass, the gauge tracks the actual voltage curve and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392088047706,"sku":"BWCS-ZTA910SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392088080474,"sku":"BWCS-ZTA910SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392088113242,"sku":"BWCS-ZTA910SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTA910SL-1.webp?v=1779143707","url":"https:\/\/batteryweb.com\/products\/zte-blade-a910-replacement-battery-385v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
