It carries OEM part number MD-2 and fits the N7010 directly. Capacity is 3.33Wh — matching the original cell specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrionvega N7010 fitment:\u003c\/strong\u003e\n    The N7010 uses a compact 44.70 × 37.70 × 5.60mm cell with a 3.7V nominal rail. This battery matches that footprint and voltage exactly. The connector and BMS handshake align with the N7010's charge IC, so the phone reads the cell state correctly from the first boot.\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 held cutoff cleanly at both ends — no low-voltage passthrough, no overcharge bleed. Charge IC communication registered without error during the test cycle.\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 against the new cell before high-current charging pushes power into an uncalibrated coulomb counter. Skip this step and the percentage readout will drift for several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the N7010 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe N7010's fuel gauge IC stores a learned discharge curve from the old cell. When a new cell goes in, that stored curve no longer matches the actual voltage-versus-capacity profile. The gauge reads voltage correctly but maps it to the wrong percentage. One full discharge down to automatic shutdown, followed by a full charge to 100%, forces the IC to rewrite its reference curve against the new cell.\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 screen draws a surge current and the cell voltage drops faster than the fuel gauge predicted. The phone's protection circuit interprets the voltage cliff as a dead cell and cuts power before the gauge hits 0%. It is not a faulty battery — it is an uncalibrated gauge still running the old cell's curve. Run two full discharge-charge cycles without fast charging and the shutdowns stop. If they persist past three cycles, check that resting voltage after a full charge sits at 4.15–4.20V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405044056154,"sku":"BWCS-AMD002SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405044088922,"sku":"BWCS-AMD002SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405044121690,"sku":"BWCS-AMD002SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMD002SL_1.webp?v=1779369841","url":"https:\/\/batteryweb.com\/products\/tim-onda-brionvega-n7010-replacement-battery-37v-900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
