It replaces the original C11P1702 cell when capacity has dropped from repeated charge cycles. The battery connects to the same board-mounted flex connector as the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV500KL and A009 platform fit:\u003c\/strong\u003e\n    These model numbers share the same PCB layout, connector pitch, and BMS handshake protocol — all drawing from the same 3.85V rail. One cell covers all variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the C11P1702 replacement through a full charge cycle on the V500KL board. The charge IC accepted the cell, BMS communication initialized correctly, and the fuel gauge IC began tracking within the first discharge pass.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell — which can cause premature charge termination or erratic percentage readings.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell has a different voltage-versus-capacity slope, so the gauge reads 25% while actual cell voltage has already hit the modem's cutoff threshold. Under screen-on or LTE load, the voltage drops sharply and the phone shuts off before the gauge reaches zero. Run one full discharge to below 5%, then charge to 100% uninterrupted — this forces the coulomb counter to re-anchor its endpoints to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores learned capacity data from the old cell in non-volatile memory. After a swap, it applies that old curve to a cell with a different internal resistance and capacity profile, producing inaccurate readings. Percentage may jump several points or flatline at a fixed number. A single full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the learned parameters — after that cycle, percentage tracking stabilises to within a few percent of actual.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391999770714,"sku":"BWCS-AUV500SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391999803482,"sku":"BWCS-AUV500SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391999836250,"sku":"BWCS-AUV500SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUV500SL-1.webp?v=1779142855","url":"https:\/\/batteryweb.com\/products\/asus-zenfone-v-live-replacement-battery-385v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
