It fits all 2012 storage variants — 8GB, 16GB, and 32GB — using OEM part number C11-ME370T. The connector and cell dimensions match the original housing at 141.60 x 68.10 x 3.80mm, so no modification is needed during installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2012 Nexus 7 variants (8GB \/ 16GB \/ 32GB):\u003c\/strong\u003e\n    All three storage models share the same physical chassis, connector pinout, and charge IC handshake. One cell fits all of them — no firmware or hardware differences affect battery compatibility across the range.\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 first-gen Nexus 7. The BMS accepted the charge IC handshake on the first cycle, held the 4.2V charge ceiling correctly, and triggered low-voltage cutoff at the expected threshold with no error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after swap:\u003c\/strong\u003e\n    After installation, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This single full cycle resets the fuel gauge IC calibration against the new cell and clears the inaccurate percentage readings that typically appear immediately after a battery swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNexus 7 shutting down at 15–25% battery remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 2012 Nexus 7 combines a power-hungry IPS display with active WiFi — a load combination that causes a sharp voltage drop in the lower charge range. When the cell voltage dips below the BMS cutoff threshold, the tablet shuts down even though the fuel gauge still shows capacity. A degraded original cell hits this cliff earlier and earlier over time. A fresh cell with full capacity pushes this voltage drop point back toward the expected range, but the fuel gauge IC still needs one recalibration cycle to read the new cell accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet showing 1% or jumping percentage values right after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nexus 7 fuel gauge IC stores a learned model of the old cell's discharge curve in memory. Swapping the physical cell does not automatically update that model, so the displayed percentage can read incorrectly — sometimes immediately dropping to 1%, sometimes jumping erratically. This is not a fault with the replacement cell. Discharge the tablet fully until it powers off on its own, then charge it to 100% without interruption. After that single complete cycle, the fuel gauge recalibrates to the new cell and percentage display stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426078031962,"sku":"BWCS-AME301SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426078064730,"sku":"BWCS-AME301SL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426078097498,"sku":"BWCS-AME301SL-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AME301SL-1.webp?v=1779930306","url":"https:\/\/batteryweb.com\/products\/google-nexus-7-replacement-battery-37v-4300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
