It fits the 10.1-inch Android tablet used for media playback, reading, and web browsing. Voltage and capacity match the original specification exactly — 3.8V, 26.6Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTab 2 A10-70 and A10-70F compatibility:\u003c\/strong\u003e\n    Both model variants share the same battery bay dimensions, connector pinout, and BMS communication protocol. The L14D2P31 and SB18C03763 are cross-referenced OEM part numbers for the same physical cell — either number confirms fitment on these models.\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 A10-70 platform. The BMS handshake completed without fault codes, the charge IC accepted the cell without interruption, and the tablet reached full charge state normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap fuel gauge reset:\u003c\/strong\u003e\n    After installing this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. The Tab 2 A10-70 fuel gauge IC calibrates against accumulated cell data — this single full cycle resets that calibration to the new cell and clears inaccurate percentage readings that commonly appear right 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\"\u003eTablet shutting down at 15–25% remaining on the A10-70\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe A10-70 drives a 10.1-inch IPS panel and maintains a constant WiFi radio — combined load that pulls significant current at once. Li-Polymer cells have a voltage curve that drops sharply below roughly 3.6V per cell, and the BMS interprets that voltage cliff as a low-battery cutoff. A degraded original battery hits that cliff earlier than the fuel gauge predicts, causing premature shutdown. Replacing the cell restores the flat mid-range voltage curve and eliminates the early cutoff — confirm by running one full calibration cycle after installation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePercentage jumping or reading incorrectly after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tab 2 A10-70 stores fuel gauge calibration data tied to the previous cell's charge and discharge history. A new cell has no matching history, so the reported percentage drifts — often reading higher than actual or jumping erratically. This is not a fault with the battery. Discharge the tablet fully to automatic shutoff, then charge to 100% without interruption. That single cycle writes new calibration data to the fuel gauge IC and stabilises the percentage display.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425989918810,"sku":"BWCS-LVA107SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425989951578,"sku":"BWCS-LVA107SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425989984346,"sku":"BWCS-LVA107SL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVA107SL-1.webp?v=1779930025","url":"https:\/\/batteryweb.com\/products\/lenovo-tab-2-a10-70-replacement-battery-38v-7000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
