It fits directly into the StarAddict 2 Plus and restores power when the original cell can no longer hold a usable charge. Dimensions are 59.40 × 46.00 × 5.10mm — confirm these against your original before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStarAddict 2 Plus cell fit:\u003c\/strong\u003e\n    The StarAddict 2 Plus runs a single-cell 3.7V nominal architecture. This replacement matches that voltage rail and physical footprint. The BMS on this phone expects a cell within a tight voltage window — this unit meets that handshake on first boot.\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 load on the StarAddict 2 Plus platform. The BMS accepted the cell without fault flags, and charge termination landed correctly at 4.2V. No thermal events during the charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use, 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 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 StarAddict 2 Plus after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the phone's fuel gauge IC is still reading the discharge curve of the old, degraded cell. The new cell hits a voltage cliff under modem or display load that the fuel gauge didn't predict — so the phone cuts power before the percentage reaches zero. The fix is one complete discharge cycle without interruption, letting the coulomb counter reset its reference point. After that cycle, the percentage readout tracks the new cell accurately and shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage, and if a replacement cell drops below roughly 2.5V per cell before installation, the BMS locks out to prevent damage. The StarAddict 2 Plus won't boot and won't show a charging indicator — it looks dead. Connect the phone to a wall charger rated at least 5V\/1A and leave it for 20–30 minutes without pressing the power button. Once the BMS sees enough voltage to exit lockout, the charging screen will appear and the phone will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404291244122,"sku":"BWCS-ZTN970XL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404291276890,"sku":"BWCS-ZTN970XL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404291309658,"sku":"BWCS-ZTN970XL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTN970XL-1.webp?v=1779369658","url":"https:\/\/batteryweb.com\/products\/srf-staraddict-2-plus-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
