It carries OEM part number V376073P and matches the original's voltage, physical footprint (73.92 × 58.72 × 3.70mm), and connector type. Fit the replacement when the original cell has lost capacity, fails to hold charge, or shows swelling.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlackView A10 fit:\u003c\/strong\u003e\n    The A10 uses a flat Li-Polymer pouch cell on a fixed voltage rail. This replacement matches that rail at 3.85V nominal, so the charge IC and protection circuit board see the same parameters as the factory cell.\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 representative 3.85V Li-Polymer platform. The BMS accepted charge current without error flags, and the protection circuit tripped correctly at both over-voltage and under-voltage thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-to-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging is applied to an uncalibrated cell.\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 BlackView A10 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A10's fuel gauge IC stores a discharge curve learned from the old cell. A new cell with a different internal resistance profile hits a voltage cliff at a different state of charge — the phone reads 25% but the cell voltage collapses under modem or display load. The BMS cuts power to protect the cell before the OS can react. One full discharge-charge cycle without fast charging forces the coulomb counter to relearn the new curve. After that cycle, the percentage readings and shutdown point should stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment on the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Li-Polymer cell typically has higher internal impedance than a worn cell that has been through hundreds of cycles. The charge IC pushes current into that higher-impedance cell and the extra resistance converts some energy to heat. This is normal for the first three to five charge cycles as the cell's impedance settles. If warmth continues beyond that point or concentrates on one spot on the back cover, check that the replacement cell is seated flat with no fold or crease in the foil pouch.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391991578714,"sku":"BWCS-BVA100SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391991611482,"sku":"BWCS-BVA100SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391991644250,"sku":"BWCS-BVA100SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BVA100SL-1.webp?v=1779142762","url":"https:\/\/batteryweb.com\/products\/blackview-a10-replacement-battery-385v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
