It slots in where the original BV-T3G sits and restores normal operation when the factory cell no longer holds a usable charge. Voltage and physical dimensions match the original: 95.60 × 43.20 × 4.00mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLumia 650 \/ RM-1154 fitment:\u003c\/strong\u003e\n    Both model references share the same battery bay geometry, connector pinout, and BMS handshake protocol. One cell covers both variants without modification.\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 Lumia 650 platform. The BMS accepted the charge IC handshake cleanly and thermal cutoff thresholds held within spec across repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge recalibration:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current 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 Lumia 650 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lumia 650's fuel gauge IC retains the discharge curve from the old degraded cell. When the new cell hits a section of the curve the IC hasn't mapped yet, the system reads voltage incorrectly and triggers an early shutdown — even though the cell still has capacity. This is not a fault with the replacement cell. One complete uninterrupted discharge-charge cycle forces the coulomb counter to rebuild its model against the new cell's actual curve. After that cycle, the reported percentage tracks accurately and shutdowns at low-SOC stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the BV-T3G sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If a replacement BV-T3G has been stored long enough, cell voltage can drop below 2.5V — the threshold at which the BMS locks out to prevent damage. The phone will show no response: no boot, no charging indicator. Connect to a wall charger rather than a PC USB port, which may not supply enough current to wake the BMS. Leave it connected for 15–20 minutes; once the cell recovers above 3.0V, the BMS releases and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392084246618,"sku":"BWCS-NK650SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392084279386,"sku":"BWCS-NK650SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392084312154,"sku":"BWCS-NK650SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK650SL-1.webp?v=1779143707","url":"https:\/\/batteryweb.com\/products\/nokia-lumia-650-replacement-battery-38v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
