It restores power to a phone that no longer holds a charge or fails to power on due to a degraded original cell. Capacity is 8.88Wh — matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS600, S601, and S630 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — the SP70A part number covers the full run of this hardware revision.\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 S600 platform. The BMS accepted the cell without fault flags, and the charge IC reached termination voltage cleanly at 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on 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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still running the discharge curve it learned from the old, degraded cell. When the new cell hits a steeper-than-expected voltage drop under modem or screen load, the phone interprets it as a critical low-voltage event and cuts power. The reported percentage at shutdown is meaningless until the IC recalibrates. Run one full drain — screen on, no charger — down to automatic shutdown, then charge uninterrupted to 100% to reset the curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the SP70A sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge during storage. If the cell drops below approximately 2.5V, the BMS enters lockout mode and blocks current flow to protect against unsafe charging of a deeply discharged cell. Plugging in a charger appears to do nothing — the phone shows no charging indicator. Connect to a 5V USB-A charger (not USB-PD) and leave it for 20–30 minutes without pressing the power button; the BMS trickle-charges the cell back above the lockout threshold, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405144817754,"sku":"BWCS-IS600XL-1","price":28.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405144850522,"sku":"BWCS-IS600XL-2","price":32.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405144883290,"sku":"BWCS-IS600XL-3","price":35.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IS600XL-1.webp?v=1779370263","url":"https:\/\/batteryweb.com\/products\/ido-s600-replacement-battery-37v-2400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
