It replaces OEM part HB506390EFW and restores power to the device when the original cell has degraded or failed to hold a charge. Voltage, connector, and physical dimensions match the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e60 Pro 5G \/ TNA-AN00 fitment:\u003c\/strong\u003e\n    Both model designations share the same battery bay dimensions (88.40 × 62.50 × 5.00mm), connector pinout, and BMS handshake protocol — so one cell covers both variants without modification.\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 the TNA-AN00 platform and confirmed the BMS accepted the cell, reported state-of-charge correctly after calibration, and held voltage within spec under screen and modem load.\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 recalibrate against the new cell's discharge curve before high-current fast charging pushes current into 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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has a slightly different discharge curve than the worn cell the fuel gauge IC was calibrated to. When voltage under load drops faster than the IC expects, the phone interprets a false low-voltage condition and cuts out before the displayed percentage reaches zero. This is not a faulty cell — it is a calibration mismatch. One full discharge to automatic cutoff followed by a complete charge to 100% resets the coulomb counter and resolves the premature shutdown in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not accepted on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHonor's proprietary fast charge protocol requires the charge IC to negotiate current limits with the BMS on the new cell. On the first cycle, the BMS may default to a conservative current ceiling until it has completed one full charge pass. If the phone shows standard charging speed instead of fast charge immediately after fitting the new battery, complete one full charge cycle on the standard charger first. Fast charge should activate normally from the second cycle onward once the BMS has logged an initial full-charge event.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391802769498,"sku":"BWCS-HNP610SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391802802266,"sku":"BWCS-HNP610SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391802835034,"sku":"BWCS-HNP610SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HNP610SL-1.webp?v=1779142181","url":"https:\/\/batteryweb.com\/products\/honor-60-pro-5g-replacement-battery-387v-4800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
