It fits the original battery bay directly, using the same connector and form factor as the OEM unit. Capacity is sourced from the product specification — 1200mAh, 4.44Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCricket A410 and Calcomp A410 compatibility:\u003c\/strong\u003e\n    These variants share the same 3.7V nominal voltage rail, physical footprint (54.90 × 44.00 × 5.20mm), and connector pinout — one cell fits all listed models 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 A410 platform. The BMS accepted charge handshake correctly, and the protection circuit triggered at the expected low-voltage cutoff without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one full discharge to automatic shutoff, then charge uninterrupted to 100% before normal use. The A410's fuel gauge IC is calibrated to the old cell's discharge curve — skipping this step causes the percentage indicator to read incorrectly for the first several cycles.\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 Cricket A410\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A410 uses a basic fuel gauge IC that maps reported percentage to voltage. When a new cell has a slightly different discharge curve than the original, the phone can hit the hardware low-voltage cutoff — typically around 3.4–3.5V per cell — while the display still reads 20–30%. This is not a fault in the battery. The phone's modem and screen draw enough instantaneous current that voltage sags below the cutoff threshold before the gauge catches up. One full discharge-charge cycle recalibrates the coulomb counter and eliminates this behaviour in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone will not power on after storage with the new cell installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that sit in storage below approximately 2.5V trigger BMS lockout — the protection circuit opens and blocks current flow entirely, even from a charger. This can happen if the phone was stored discharged for weeks before the replacement cell arrived. To recover: connect to a wall charger (not a USB port) and leave it for 15–20 minutes without pressing the power button. The charge IC applies a trickle current that slowly brings cell voltage above the BMS re-enable threshold, typically 2.9–3.0V, at which point normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405082198106,"sku":"BWCS-ZTC410SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405082230874,"sku":"BWCS-ZTC410SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405082263642,"sku":"BWCS-ZTC410SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTC410SL-1.webp?v=1779369934","url":"https:\/\/batteryweb.com\/products\/zte-cricket-a410-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
