It uses OEM part number BL-A67CT and fits directly into the Outlast 5G chassis without modification. Capacity matches the factory cell at 15.4Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOutlast 5G and SN509C compatibility:\u003c\/strong\u003e\n    Both model references share the same physical footprint, connector pinout, and BMS handshake requirements — the BL-A67CT part number covers both. The charge IC on the Outlast 5G expects a 4.40V charge cutoff, which this cell supports.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Outlast 5G charge IC and confirmed BMS communication, charge termination at 4.40V, and correct cell identification. The protection circuit tripped correctly at low-voltage cutoff during our discharge sweep.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installation, disable fast charging and run one full discharge-charge cycle at standard rate. The Outlast 5G fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve — skipping this step causes the percentage to read inaccurately until the IC self-corrects.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still mapped to the old cell's discharge curve. The new cell hits a voltage cliff under modem or screen load — the phone shuts down even though the reported percentage looks safe. The fuel gauge has not yet learned where the new cell's actual low-voltage threshold sits. One full discharge to auto-off, followed by a complete charge, forces the IC to remap its curve to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not accepted on the first cycle after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle, the Outlast 5G charge IC may default to trickle or standard current rather than fast charge. The new BMS needs to complete one full handshake cycle with the phone's charge IC before the fast-charge protocol is accepted. This is not a fault — it resolves after the first complete charge. If fast charging still does not engage after two full cycles, confirm the charger output is USB-PD compliant and check the USB-C port for debris.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391775080538,"sku":"BWCS-ATS219SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391775113306,"sku":"BWCS-ATS219SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391775146074,"sku":"BWCS-ATS219SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ATS219SL-1.webp?v=1779141870","url":"https:\/\/batteryweb.com\/products\/cricket-outlast-5g-replacement-battery-385v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
