It fits the GT Neo6 SE directly, matching the OEM voltage, connector, and BMS communication profile. Capacity is rated at 20.72Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT Neo6 SE fit:\u003c\/strong\u003e\n    The GT Neo6 SE uses a dual-cell Li-Polymer stack running a 7.82V nominal rail. The BLPA45 matches that stack voltage and the proprietary BMS handshake the charge IC expects — a mismatched nominal voltage causes the charge IC to reject the cell entirely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the GT Neo6 SE charge IC and confirmed BMS authentication passed on the first connection. The coulomb counter accepted the new cell after one full discharge-charge cycle without throwing a battery health error in the OS.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after installation:\u003c\/strong\u003e\n    On first use, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% on standard charge. This gives the fuel gauge IC one clean reference cycle against the new cell's actual discharge curve 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\"\u003eWhy the GT Neo6 SE reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT Neo6 SE uses a coulomb counter that builds its percentage model from the previous cell's discharge curve. When a new cell goes in, the counter is still referencing the old curve — which means the displayed percentage drifts from reality, often reading high then snapping down. The OS will not automatically reset this model on power-up. One full discharge-to-shutdown cycle followed by a complete charge forces the coulomb counter to rebuild its reference map against the new cell.\u003c\/p\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 when the fuel gauge IC hasn't recalibrated and the phone's percentage reading no longer matches the cell's actual remaining voltage. Under a high-draw event — modem burst, screen-on wake, or a GPU spike — the cell voltage drops below the BMS cutoff threshold even though the OS shows charge remaining. The BMS sees the voltage cliff and cuts output immediately. Run one full unconstrained discharge cycle to let the gauge IC relearn where the real cutoff voltage sits, which on this cell is approximately 3.0V per cell under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391785402458,"sku":"BWCS-OPT610SL-1","price":50.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43391785435226,"sku":"BWCS-OPT610SL-2","price":59.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43391785467994,"sku":"BWCS-OPT610SL-3","price":66.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPT610SL-1.webp?v=1779141908","url":"https:\/\/batteryweb.com\/products\/realme-gt-neo6-se-replacement-battery-782v-2650mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
