It replaces OEM part numbers BAT-B10, PGF295686HT, and KT.0010S.013. Capacity is 7.41Wh, matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLiquid Jade, Jade Plus, and S55 compatibility:\u003c\/strong\u003e\n    All three models share the same battery footprint, connector pinout, and BMS handshake protocol — the S55 and Jade Plus use the identical voltage rail and charge IC as the original Liquid Jade, so one cell covers all three variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a Liquid Jade unit, confirming the BMS accepted the cell without error flags and that the charge IC reached full termination voltage without tripping overcurrent protection.\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 coulomb counter.\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 Liquid Jade after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a steeper voltage curve at low state-of-charge than a worn original. When the modem fires a high-power transmission burst or the screen backlight peaks, the cell voltage briefly dips below the BMS cutoff threshold — even though the fuel gauge still reads 20–30%. The phone treats this as a hard undervoltage event and shuts down immediately. Run two full discharge-charge cycles without fast charging to let the fuel gauge IC map the real voltage curve of the new cell, and the shutdowns will stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery during the first few charges after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh lithium-polymer cell has higher internal impedance than a cell that has been cycled. The charge IC on the Liquid Jade pushes the same current rate it used on the broken-in original, and higher impedance converts more of that current to heat. This is normal for the first three to five charge cycles as impedance drops. If the phone stays noticeably warm beyond five cycles, check that the replacement cell dimensions — 86.58 x 55.70 x 3.50 mm — match and that the cell is seated flat with no pressure on the connector.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404156797018,"sku":"BWCS-ACS560SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404156829786,"sku":"BWCS-ACS560SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404156862554,"sku":"BWCS-ACS560SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACS560SL-1.webp?v=1779369080","url":"https:\/\/batteryweb.com\/products\/acer-liquid-jade-replacement-battery-38v-1950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
