It replaces the original GI03 cell when the existing battery no longer holds enough charge for normal daily use. Dimensions are 74.68 × 60.44 × 4.35mm — confirm clearance before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eME pure and GS53-6 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, connector pinout, and BMS handshake protocol, which is why a single GI03 cell covers both. The 3.8V nominal rail matches what each device's charge IC expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on the GS53-6. The BMS accepted the charge IC handshake without fault codes, and the protection circuit tripped 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 fitting, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This lets the phone's fuel gauge IC map the new cell's discharge curve before high-current charging 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 Gigaset ME pure after a cell swap\u003c\/h3\u003e\n\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. The new cell has a steeper voltage drop under modem and screen load than the IC expects at that state of charge. The phone interprets the voltage sag as a critical low event and cuts power before the actual remaining capacity is used. One full slow-rate discharge-to-charge cycle forces the coulomb counter to re-anchor its curve to the new cell — after that, shutdowns at 20–30% typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the GI03 sat in storage discharged\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells that drop below approximately 2.5V trigger BMS lockout to prevent reverse-polarity cell damage. The phone will show nothing when connected to a charger for the first few minutes — this is normal BMS behaviour, not a dead battery. Connect to a wall charger rated at least 1A and leave it undisturbed for 15–20 minutes. Once the cell climbs back above the BMS re-entry threshold, the charge IC takes over and the boot screen should appear.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392046727258,"sku":"BWCS-GMS536SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392046760026,"sku":"BWCS-GMS536SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392046792794,"sku":"BWCS-GMS536SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GMS536SL-1.webp?v=1779143125","url":"https:\/\/batteryweb.com\/products\/gigaset-me-pure-replacement-battery-38v-3200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
