It fits the same footprint at 76.40 x 58.26 x 4.00mm and connects to the same BMS interface the phone expects on startup.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZA550KL and Dual SIM variant compatibility:\u003c\/strong\u003e\n    All four variants — standard, Dual SIM, Dual SIM LTE, and ZA550KL — share the same 3.8V power rail, connector pinout, and BMS handshake protocol. One cell covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on ZA550KL hardware. The BMS accepted the cell without fault flags, coulomb counter initialised cleanly, and the charge IC held the 4.35V upper cutoff as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge disable:\u003c\/strong\u003e\n    On first use after installation, turn off fast charging in Settings and run one full discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on an uncalibrated cell.\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 Live L1\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity issue. When the modem transmits or the screen peaks in brightness, current draw spikes sharply. If the cell's internal resistance is high — common in a degraded original battery — voltage sags below the BMS cutoff threshold even though the fuel gauge still shows 20–30%. The phone interprets this as a fault and shuts down to protect the cell. A new cell with lower internal resistance removes the sag and eliminates the false cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or reading incorrectly after the swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZenFone Live L1 uses a fuel gauge IC that builds its charge estimate from the discharge curve of the original cell. After a swap, that calibration data no longer matches the new cell's chemistry profile. The result is erratic percentage readings — jumps of 5–15% in either direction, or a sudden drop to 1% from 40%. Run one uninterrupted full discharge down to automatic shutdown, then charge to 100% without interruption. That single cycle gives the fuel gauge IC enough data to recalibrate against the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391997902938,"sku":"BWCS-AUZ100SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391997935706,"sku":"BWCS-AUZ100SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391997968474,"sku":"BWCS-AUZ100SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUZ100SL-1.webp?v=1779142855","url":"https:\/\/batteryweb.com\/products\/asus-zenfone-live-l1-replacement-battery-38v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
