It replaces OEM part ZAW1975Q when the original cell no longer holds a usable charge. The battery fits the 7-inch Android tablet form factor with dimensions of 127.10 x 60.15 x 3.30mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA1-713 and A1-713HD compatibility:\u003c\/strong\u003e\n    Both tablet variants share the same physical battery bay, connector pinout, and charge IC communication protocol. One cell fits both — no hardware modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the A1-713 platform. The BMS accepted the charge handshake correctly on first connection, and the protection circuit responded to over-voltage and thermal thresholds within spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without using the device. This forces the fuel gauge IC to recalibrate against the new cell's actual capacity curve and clears the inaccurate percentage readings that typically appear after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Iconia Tab 7 shuts down at 15–25% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A1-713's fuel gauge IC stores a learned capacity map from the original cell. When a new cell goes in, that map is stale — the IC thinks the voltage floor is higher than it actually is. Under combined display and Wi-Fi load, voltage sags briefly, the IC reads that sag against the old map, and the tablet shuts down even though real charge remains. One full discharge-to-shutoff cycle followed by a complete uninterrupted charge corrects the map and stops premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after fitting a replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Iconia Tab 7's charge controller negotiates charge rate during the first accepted charge cycle on a new cell. Until that cycle completes, the device may fall back to standard 5V charging speeds. This is not a fault with the replacement battery — it is the controller validating the new cell's impedance profile. Charge the tablet fully from near-flat without interruption once, and normal charge rate resumes on subsequent cycles.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426028027994,"sku":"BWCS-ACW713SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426028060762,"sku":"BWCS-ACW713SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426028093530,"sku":"BWCS-ACW713SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACW713SL-1.webp?v=1779930195","url":"https:\/\/batteryweb.com\/products\/acer-iconia-tab-7-replacement-battery-38v-3400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
