Part number HE401 matches the original cell footprint at 79.00 × 61.60 × 4.10mm. Swap it when the original cell no longer holds a usable charge across a normal day of calls and screen time.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSplendor \/ Icon 3 platform compatibility:\u003c\/strong\u003e\n    The EC211002 and EC211003 share the same mainboard voltage rail and connector pinout as the branded Splendor and Icon 3 variants. One cell services all four models without any adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the EC211002 mainboard. The BMS accepted the charge handshake cleanly, protection thresholds tripped correctly at both ends of the voltage window, and no thermal anomalies appeared during constant-current phase.\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 complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before fast-charge current is applied to an uncalibrated cell.\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 Splendor after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a discharge curve the fuel gauge IC has never seen. The IC is still referencing the old cell's voltage-to-capacity map, so it misreads remaining charge. Under load from the modem or display, the actual cell voltage drops below the BMS cutoff threshold before the OS percentage reaches zero. The phone shuts off mid-use at what looks like 25% remaining. One full discharge-to-shutdown followed by a full charge resets the coulomb counter against the new cell curve and clears this behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone will not power on after the HE401 has been sitting discharged in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge slowly in storage. If the cell voltage drops below approximately 2.5V per cell, the BMS enters lockout mode and blocks current flow to protect the cell from damage. Plugging in the charger may show no response at all — no charging indicator, no boot. Connect the phone to a wall adapter and leave it undisturbed for 15–20 minutes. The charge IC will trickle-feed current below normal charge rate until the cell climbs above the BMS re-enable threshold, typically around 3.0V, at which point normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391790055514,"sku":"BWCS-CKT211SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391790088282,"sku":"BWCS-CKT211SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391790121050,"sku":"BWCS-CKT211SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CKT211SL-1.webp?v=1779142036","url":"https:\/\/batteryweb.com\/products\/cricket-splendor-replacement-battery-385v-3600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
