It uses OEM part number C11P1506 and slots into the same battery bay as the original cell. Capacity is 2000mAh (7.6Wh), matching the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit — Live Dual SIM, G500TG, ZenFone Go 5.5:\u003c\/strong\u003e\n    These devices share the same 3.8V power rail, identical connector pinout, and a common BMS handshake protocol, which is why a single C11P1506 cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a Live Dual SIM unit. The BMS accepted the cell on first connection, balanced correctly across the protection circuit, and hit the expected 4.35V charge termination point without false cutoffs.\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 and run one complete discharge-charge cycle. The fuel gauge IC on these Asus devices calibrates its coulomb counter against the new cell's discharge curve — skipping this step causes the percentage readout to drift by up to 15% in the first week.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the ZenFone Go and Live Dual SIM\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is the most reported failure mode with aged original cells on these devices. When the cell's internal resistance rises enough that it cannot sustain voltage under modem transmission or screen backlight load, the voltage drops below the BMS cutoff threshold even though the fuel gauge still shows charge remaining. The phone cuts out because the protection circuit sees a voltage cliff the coulomb counter did not predict. Replacing the cell eliminates the resistance problem — the BMS trips will stop once the new cell holds above 3.5V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reporting wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the Live Dual SIM stores a learned discharge curve from the old cell. After a swap, it applies that old curve to the new cell and produces inaccurate percentage readings — often jumping 10–20% or dropping suddenly. This is not a cell defect. Run one full discharge to 0% shutdown, then charge uninterrupted to 100% to force the IC to write a fresh calibration curve. After that cycle, percentage tracking stabilises and readings stay within 3–5% of actual charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392104955994,"sku":"BWCS-AUG500SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392104988762,"sku":"BWCS-AUG500SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392105021530,"sku":"BWCS-AUG500SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUG500SL-1.webp?v=1779143796","url":"https:\/\/batteryweb.com\/products\/asus-live-dual-sim-replacement-battery-38v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
