It replaces OEM part numbers LIP-880, LIP-880PD, LIP-880PD-B, and 2-632-807-11. The cell fits the original battery bay without modification and connects via the factory connector.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNW-HD5 series compatibility:\u003c\/strong\u003e\n    All NW-HD5 variants share the same battery bay dimensions, voltage rail, and LIP-880 connector pinout. One replacement cell covers the full range of HD5 models without adaptation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell in an NW-HD5 unit and confirmed the BMS accepted a full charge without fault codes, held voltage above 3.5V through the bulk of the discharge curve, and tripped the low-voltage cutoff at the correct threshold before the device shut down.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after cell swap:\u003c\/strong\u003e\n    After installing a new cell, charge fully before first use. The NW-HD5 firmware often detects a low-state cell as a deep-discharge condition and may show no charging activity for the first 20–30 minutes while trickle current brings the cell above the threshold for normal charge acceptance.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping after cell swap on the NW-HD5\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new LIP-880 cell, the NW-HD5 battery indicator may jump erratically — showing 80%, then 40%, then 90% across short sessions. The player's fuel gauge is calibrated against voltage thresholds set by the original aged cell, not the new one. The firmware needs two or three full charge-and-discharge cycles to recalibrate its voltage-to-percentage mapping. Run the player down to automatic shutdown, then charge fully, and repeat — the indicator stabilises by the third cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the battery indicator reads empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome NW-HD5 units cut audio and shut down while the indicator still shows one or two bars remaining. The audio amplifier draws a current spike during output, and at the tail end of the Li-ion discharge curve — where cell voltage drops steeply — the amplifier can pull voltage below the BMS cutoff threshold before the indicator catches up. This is a voltage sag issue, not a capacity issue. If it happens consistently, charge the cell to 4.2V and confirm the player runs normally from full charge; if cutoff still triggers early, check that the battery contacts are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381349908570,"sku":"BWCS-HD5SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381349941338,"sku":"BWCS-HD5SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381349974106,"sku":"BWCS-HD5SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HD5SL-1.webp?v=1778900059","url":"https:\/\/batteryweb.com\/products\/sony-nw-hd5-silver-replacement-battery-37v-980mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
