It matches the OEM part number Li3714T42P3h765039 and fits the same physical envelope — 75.50 × 49.80 × 3.80mm. Voltage and capacity come from the product data, not estimates.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBlade A3 \/ A5 \/ T220 \/ T230 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell covers all of them without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through charge-discharge cycles on the Blade A3 platform. The BMS accepted the cell on first insertion, and the charge IC negotiated correctly without triggering protection lockout.\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 map the new cell's discharge curve before high-current charging pushes 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 A3 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still references the discharge curve of the old, degraded cell. When screen or modem load spikes, the new cell's voltage drops faster than the IC expects — it interprets this as a critical low and cuts power. It is not a defective battery. One full discharge-charge cycle without fast charging lets the coulomb counter recalibrate against the real discharge curve, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left uncharged for extended periods can drop below 2.5V per cell, triggering BMS lockout — the battery stops responding to protect against unsafe recovery charging. The phone shows nothing when connected to a charger. Connect to a wall adapter and leave it for 20–30 minutes without pressing the power button. The BMS needs a low-current trickle to bring the cell voltage back above the re-initialisation threshold, typically around 2.9V, before normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392083394650,"sku":"BWCS-ZTA300SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392083427418,"sku":"BWCS-ZTA300SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392083460186,"sku":"BWCS-ZTA300SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTA300SL-1.webp?v=1779143708","url":"https:\/\/batteryweb.com\/products\/zte-blade-a3-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
