It replaces a worn or degraded original battery that can no longer hold adequate charge under normal use. Capacity is rated at 7.98Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA360T fit note:\u003c\/strong\u003e\n    The A360T uses a removable back cover with a direct-drop connector — no flex cable or adhesive retention. The BL228 seats into the battery bay and locks to the contact pins without tools. Voltage rail and connector pitch match the original exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the BL228 through a full discharge-charge cycle on the A360T. The BMS accepted the charge handshake on the first cycle, and the protection circuit tripped correctly at the low-voltage cutoff threshold during deep discharge simulation.\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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the A360T reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A360T uses a coulomb counter that tracks charge relative to the previous cell's discharge curve. When a new cell goes in, the stored curve no longer matches the actual cell chemistry. The phone reads a stale model and reports percentage that drifts from reality. One full discharge-to-shutdown followed by a full uninterrupted charge resets the calibration and brings the gauge back into alignment.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff — the cell voltage drops sharply under modem or screen load before the displayed percentage predicts it. The fuel gauge IC is still running an old curve and does not flag the real knee point of the new cell. The phone's protection circuit cuts power before the OS can react. Run one full discharge cycle without interruption and the gauge will map the actual cliff point, eliminating early shutdowns.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404261163098,"sku":"BWCS-LVA360SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404261195866,"sku":"BWCS-LVA360SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404261228634,"sku":"BWCS-LVA360SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVA360SL-1.webp?v=1779369511","url":"https:\/\/batteryweb.com\/products\/lenovo-a360t-replacement-battery-38v-2100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
