It matches the OEM voltage, capacity, and connector spec for a direct swap. Capacity is 3000mAh (22.2Wh) as confirmed by product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVIERA UN-10N10D, UN-15N10D, UN-15TD10D fit:\u003c\/strong\u003e\n    These three VIERA tablet models share the same 7.4V battery rail, connector pinout, and BMS communication protocol — which is why both OEM part numbers N4HULQA00059 and N4HULQA00061 cross-reference across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the VIERA platform. The BMS accepted the cell without fault codes, charge termination triggered correctly at full capacity, and low-voltage cutoff fired at the expected threshold under combined display and Wi-Fi load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after installation:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate against the new cell and clears the inaccurate percentage readings that appear immediately after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVIERA tablet shutting down at 15–25% remaining after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC was calibrated to the wear curve of the old cell. When a new cell is fitted, the IC misreads the state of charge and triggers a protective shutdown well before the battery is actually empty. The combined load of the display backlight and active Wi-Fi accelerates the voltage drop at that threshold, making the cutoff appear earlier than expected. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% realigns the IC to the new cell's actual voltage curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after battery replacement on the VIERA UN-series\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VIERA tablet's charge controller uses a negotiation handshake with the battery's BMS before enabling the higher charge rate. On the first cycle with a new cell, the controller defaults to standard charge current until it has completed one accepted charge session and logged the cell's response data. This is normal behaviour — not a fault with the battery or charger. After the first full charge cycle completes, the fast charge option becomes available through the device's normal charging protocol.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425822703706,"sku":"BWCS-PNR150SL-1","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425822736474,"sku":"BWCS-PNR150SL-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425822769242,"sku":"BWCS-PNR150SL-3","price":124.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PNR150SL-1.webp?v=1779929853","url":"https:\/\/batteryweb.com\/products\/panasonic-viera-un-10n10d-replacement-battery-74v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
