It fits directly into the battery bay and connects to the same flex cable and fuel gauge circuit as the factory unit. Capacity figures come from the product data, not the web — 2500mAh is what this cell ships at.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNeva 80 \/ Neva 80 LTE \/ TT175S fitment:\u003c\/strong\u003e\n    These three models share the same battery bay dimensions (76.80 × 59.60 × 3.20mm), the same 3.85V nominal rail, and the same flex connector pin-out. A single cell covers all three 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 Neva 80 platform. The BMS accepted the cell without fault codes, and the charge IC held the correct 4.35V upper cutoff throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-charge cycle. This gives the fuel gauge IC a complete discharge curve to map against the new cell before the charge IC pushes higher current into an uncalibrated counter.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh lithium-polymer cell has a slightly different voltage-discharge curve than a degraded original. The fuel gauge IC on the Neva 80 was calibrated to the old cell's curve, so it reads 25% when the new cell's open-circuit voltage is already near the low-load threshold. Under modem transmit or screen-on load, voltage drops sharply and the BMS cuts power before the OS can log a low-battery warning. One full discharge-charge cycle with fast charging disabled forces the coulomb counter to remap to the new cell. After that cycle, shutdown should move back to 3–5%.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells self-discharge during storage. If this cell shipped or was stored in a discharged state, the BMS may have tripped its deep-discharge lockout — typically below 2.5V per cell. The phone will not respond to the power button and may show no charge indicator at all. Connect the phone to a wall charger — not a PC port — and leave it for 20–30 minutes without pressing anything. The charge IC on most Neva 80 units will trickle current into the cell at around 50–100mA until it climbs above 3.0V, at which point the BMS re-enables the output rail and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392087916634,"sku":"BWCS-ZTA910SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392087949402,"sku":"BWCS-ZTA910SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392087982170,"sku":"BWCS-ZTA910SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTA910SL-1.webp?v=1779143707","url":"https:\/\/batteryweb.com\/products\/orange-neva-80-replacement-battery-385v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
