It restores power to the processor, display stack, and wireless radios when the original cell can no longer hold adequate charge. Dimensions are 90.31 × 59.51 × 3.23mm — verify fitment before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXperia ZL platform compatibility:\u003c\/strong\u003e\n    The C6502, C6503, C6505, and C6506 all share the same battery bay dimensions, voltage rail, and connector pinout. One cell revision covers the full cluster — no modifications needed across these variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the Xperia ZL platform. The BMS handshake completed correctly, charge IC accepted the cell without fault codes, and protection circuits tripped at the expected voltage thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% uninterrupted. This gives the fuel gauge IC a clean reference curve against the new cell before high-current charging begins.\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 Xperia C6502 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Xperia ZL's fuel gauge IC retains the discharge curve from the old, degraded cell. When a new cell is fitted, the IC misreads remaining capacity at the point the old cell used to sag. The modem radio and display draw spike current at around 20–30% reported charge, and if the IC hasn't recalibrated, it triggers a low-voltage shutdown even though actual cell voltage is fine. One full uninterrupted discharge-to-charge cycle corrects the coulomb counter and eliminates spurious shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells self-discharge during storage. If this cell dropped below 2.5V per cell before installation, the BMS enters lockout mode and blocks current flow to protect the cell from damage. Plugging in a charger with a normal cable may show no response for the first 10–15 minutes — this is the charge IC trickling current to recover the cell from below the BMS threshold. Keep the cable connected; once voltage climbs above 2.8V, the BMS re-enables and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404292522074,"sku":"BWCS-ERL350SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404292554842,"sku":"BWCS-ERL350SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404292587610,"sku":"BWCS-ERL350SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERL350SL-1.webp?v=1779369642","url":"https:\/\/batteryweb.com\/products\/sony-ericsson-xperia-c6502-replacement-battery-37v-2300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
