It replaces OEM part TLP058B2 directly. Fit this battery when the original no longer holds a useful charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTab Prime 7 and VFD-1400 compatibility:\u003c\/strong\u003e\n    Both model numbers refer to the same hardware platform. They share the same connector pinout, BMS handshake protocol, and 3.85V charge termination voltage — one battery covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the TLP058B2 replacement through charge and discharge cycles on the Tab Prime 7 platform. The BMS accepted the cell, charge termination triggered correctly at full voltage, and no fault flags appeared during the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After fitting this battery, run the tablet down to automatic shutoff, then charge it in one uninterrupted session to 100%. This forces the fuel gauge IC to recalibrate against the new cell. Skip this step and the percentage display will read against the old cell's wear profile.\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% after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tab Prime 7 draws combined load from the display backlight, Wi-Fi radio, and processor simultaneously. Under that load, a freshly fitted cell with an uncalibrated fuel gauge hits a voltage cliff that the OS misreads as a low-battery emergency. The tablet shuts down even though cell capacity remains. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resets the fuel gauge IC and eliminates false shutdowns. After calibration, the cutoff should occur at or below 3.5V cell voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging unavailable after fitting the replacement battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUSB-PD negotiation on the Tab Prime 7 depends on the charge IC reading the new cell as accepted after at least one completed charge cycle. Until that cycle runs, the charge controller defaults to standard 5V input and declines higher-voltage negotiation. Plug in with the original charger and allow one full charge from low to 100% without interruption. After that cycle completes, USB-PD negotiation resumes and fast charging becomes available again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425829912666,"sku":"BWCS-AVF140SL-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425829945434,"sku":"BWCS-AVF140SL-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425829978202,"sku":"BWCS-AVF140SL-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AVF140SL-1.webp?v=1779929903","url":"https:\/\/batteryweb.com\/products\/vodafone-tab-prime-7-replacement-battery-385v-5500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
