It fits the original battery slot and matches the OEM part numbers B11P1510 and B11Bj9c. If your Zenfone Go TV shuts down unexpectedly or no longer holds a charge through a normal day, this cell replaces the degraded original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZenfone Go TV and X013DB fitment:\u003c\/strong\u003e\n    Both model designations use the same battery bay dimensions, connector pinout, and BMS communication protocol. One replacement covers either variant without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge and load discharge on the X013DB platform. The BMS handshake completed on the first connection, charge current ramped correctly through CC\/CV stages, and the protection circuit tripped at expected undervoltage threshold.\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 current into an uncalibrated state. Skip this step and the OS will report incorrect percentages for several days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Zenfone Go TV reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zenfone Go TV uses a coulomb counter and a stored discharge curve to estimate state of charge. When you install a new cell, that stored curve still reflects the old, degraded battery. Until the fuel gauge IC observes one full discharge-to-charge cycle on the new cell, its percentage readout will be inaccurate — often reading 100% and then dropping sharply. Run one full cycle from 100% down to automatic shutdown, then charge uninterrupted to 100%, and the gauge recalibrates against the new cell's actual voltage-to-capacity profile.\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 radio or display draws a short burst of high current and the cell voltage drops below the BMS cutoff threshold — even though the fuel gauge still shows charge remaining. It is a voltage sag issue, not a capacity issue. The fuel gauge IC has not yet mapped where the new cell's voltage cliff sits under real load conditions. After two or three full discharge-charge cycles, the gauge recalibrates and the OS learns to trigger shutdown earlier, before the voltage sag crosses 3.0V per cell under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392083296346,"sku":"BWCS-AUB551SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392083329114,"sku":"BWCS-AUB551SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392083361882,"sku":"BWCS-AUB551SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUB551SL-1.webp?v=1779143684","url":"https:\/\/batteryweb.com\/products\/asus-zenfone-go-tv-replacement-battery-38v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
