It replaces OEM part PT34H406082J and PT34H406082W. If the original battery swells, drops capacity sharply, or refuses to charge, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eICON 2 and U325AC compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and charge IC protocol. The 80.70 × 59.80 × 3.80mm cell fits either chassis without modification. The BMS handshake is identical across both variants.\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 ICON 2 platform. The BMS accepted the charge IC handshake on the first cycle, voltage held steady across screen-on and modem-active load, and the protection circuit triggered correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one full discharge-to-charge cycle at standard rate. This gives the fuel gauge IC time to map the new cell's discharge curve before fast-charge current is applied to an uncalibrated cell — preventing erratic percentage readings from the first day.\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 ICON 2 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ICON 2's fuel gauge IC holds a discharge curve calibrated to the original cell. A new cell with a different internal resistance profile hits a voltage cliff at a different state of charge — the phone sees voltage drop under modem or display load and shuts down before the reported percentage reaches zero. This is not a fault with the replacement cell. One complete discharge cycle at standard charge rate lets the coulomb counter reset its endpoint reference against the new cell. After that cycle, the reported percentage and actual cutoff voltage align correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle after a cell swap, the ICON 2's charge IC can refuse to enter fast-charge mode. The controller reads the new cell's impedance as outside the expected range and defaults to standard 5V charging as a protection measure. This is normal BMS behaviour on a fresh cell — it is not a fault with the charger or the replacement battery. Complete one full standard-rate charge cycle first, then reconnect to a fast charger; the charge IC will accept the higher current once it has one baseline cycle on record.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391874170970,"sku":"BWCS-CKA325SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391874203738,"sku":"BWCS-CKA325SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391874236506,"sku":"BWCS-CKA325SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CKA325SL-1.webp?v=1779142412","url":"https:\/\/batteryweb.com\/products\/cricket-icon-2-replacement-battery-385v-3300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
