It matches the original part number Li3822T43P3h736044 and fits the shared battery bay used across both models. Capacity is 1800mAh (6.84Wh) — drawn directly from the product specification, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade A460 and Blade L4 compatibility:\u003c\/strong\u003e\n    Both models share the same battery form factor, connector pinout, and BMS handshake protocol — ZTE used a common battery platform across this budget Android range, so one cell covers both devices 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 the Blade A460 platform. The BMS accepted the new cell without flagging a fault, and the charge IC stepped through CC\/CV phases correctly across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-to-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve 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\"\u003eSudden shutdown at 20–30% on the Blade A460 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still referencing the discharge curve of the old, degraded cell. When the new cell hits a voltage point the IC interprets as critically low — typically around 3.5V under modem or screen load — the phone shuts down even though usable capacity remains. The fix is one complete discharge cycle without interruption, taken down to automatic shutdown, then a full uninterrupted charge to 100%. After that cycle the coulomb counter resets against the actual new cell curve and percentage reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage, and if the voltage drops below approximately 2.5V per cell the BMS trips into lockout to prevent damage. The phone will show nothing — no charging screen, no vibration — when you first connect a cable. Connect the phone to a wall charger rated at least 1A and leave it for 20–30 minutes before attempting to power on. The charge IC needs to push a trickle current into the cell long enough to bring voltage above the BMS recovery threshold, which sits around 2.9V, before normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392072843354,"sku":"BWCS-ZTA460SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392072876122,"sku":"BWCS-ZTA460SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392072908890,"sku":"BWCS-ZTA460SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTA460SL-1.webp?v=1779143639","url":"https:\/\/batteryweb.com\/products\/zte-blade-a460-replacement-battery-38v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
