It matches OEM part numbers ICP37\/54\/72SA and 365371PLV. Rated at 8.36Wh, it restores full power to calls, messaging, apps, and display functions when the original cell has degraded or stopped holding a charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade A462 and A310 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, voltage rail, and connector pinout. The BMS on each device uses the same charge termination threshold, so one cell works across both without modification.\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 Blade A462 unit. The BMS accepted the cell without fault codes, charge termination triggered correctly at 4.35V, and protection cutoff engaged at the expected low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after installation:\u003c\/strong\u003e\n    On first use after fitting this cell, disable fast charging and complete one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC one clean reference cycle against the new cell's discharge curve before any high-current charging session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Blade A462 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Blade A462 uses a coulomb-counting fuel gauge IC that builds its capacity model from the original cell's charge and discharge history. When a new cell goes in, that stored model no longer matches the actual cell chemistry. The gauge reads state-of-charge against the old curve, so it can show 40% while the cell is actually close to cutoff voltage. One complete discharge-to-shutdown followed by an uninterrupted charge to 100% forces the IC to write a fresh capacity baseline against the new cell.\u003c\/p\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 when the cell voltage drops sharply under the load spike from the modem radio or display backlight — a voltage cliff the fuel gauge did not predict. The phone's hardware protection trips before the OS can log a low-battery warning. It is not a faulty cell; it is an uncalibrated gauge sending the wrong percentage to the OS. Run one full discharge cycle without interruption and let the phone shut down on its own at 0%, then charge to 100%. After that cycle, the gauge's voltage-to-percentage mapping aligns with the new cell and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392053149786,"sku":"BWCS-ZTA462SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392053182554,"sku":"BWCS-ZTA462SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392053215322,"sku":"BWCS-ZTA462SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTA462SL-1.webp?v=1779143526","url":"https:\/\/batteryweb.com\/products\/zte-blade-a462-replacement-battery-38v-2200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
