It fits RM-1030 and RM-1042 board revisions and uses the OEM BN-02 form factor. The cell sits in the original battery bay with no modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRM-1030 and RM-1042 compatibility:\u003c\/strong\u003e\n    Both board revisions run the same 3.7V rail and use the same three-contact connector with no BMS handshake variation between single-SIM and Dual SIM models — one cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an RM-1042 unit through full charge and discharge passes. The BMS accepted the cell without a protection-circuit lockout, and charge termination triggered correctly at 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge to automatic shutdown followed by a full charge before enabling any fast or turbo charge options — this gives the phone's coulomb counter a clean reference curve against the new cell's discharge profile.\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 Nokia XL after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nokia XL uses a fuel gauge IC that builds its state-of-charge model from the discharge curve of the original cell. A new cell has a slightly different internal resistance and voltage-versus-capacity curve. When the phone draws a burst of current — mobile data handoff or screen-on peak — the new cell's voltage drops briefly below the IC's shutdown threshold even though capacity remains. The IC interprets this as an empty battery and cuts power. One full discharge-to-shutdown cycle followed by a complete charge resets the reference and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells in storage self-discharge slowly. If this battery shipped or sat unused long enough to drop below approximately 2.5V per cell, the BMS engages a lockout to prevent damage from an over-discharged state. The phone shows no response — no charging animation, no boot. Connect the phone to a wall charger rated at least 1A and leave it undisturbed for 20–30 minutes without pressing the power button. The charge IC trickle-feeds current into the cell until it clears the BMS lockout threshold, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404249006170,"sku":"BWCS-NK103SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404249038938,"sku":"BWCS-NK103SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404249071706,"sku":"BWCS-NK103SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK103SL-1.webp?v=1779369448","url":"https:\/\/batteryweb.com\/products\/nokia-nokia-xl-replacement-battery-37v-1650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
