It fits the clip-based Shuffle — the model without a screen, controlled by the inline remote on the headphone cable. The OEM part number is 616-0429.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3rd Generation Shuffle fit:\u003c\/strong\u003e\n    The 3rd Gen Shuffle uses a smaller cell format than the 2nd or 4th Gen. The 616-0429 matches the correct cell dimensions (26.19 × 13.79 × 3.49mm) and connector orientation. Swapping a cell from a different generation will not fit the board correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a 3rd Gen Shuffle. The BMS accepted charge current without fault flags. Voltage held steady across playback load and tapered cleanly into the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charge behaviour:\u003c\/strong\u003e\n    After installing a new cell, plug the Shuffle into iTunes via USB rather than a wall adapter first. The 3rd Gen Shuffle relies on the USB host for its initial charge handshake — a wall adapter alone may not start current flow on a freshly installed cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the iPod Shuffle 3rd Gen goes dark after weeks in a drawer\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt 73mAh, this cell has very little reserve capacity. Stored without a charge for more than a few weeks, the cell voltage can drop below the BMS protection threshold — typically around 2.5V. When that happens, the Shuffle will not respond to the power button at all. Connect it to a powered USB port and leave it for 30 to 45 minutes before attempting to power on. The BMS needs a trickle current to recover the cell voltage above the wake threshold before it will pass normal charge current.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the status light shows low battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the audio amplifier in the Shuffle draws a short current spike when driving headphones, and near the end of discharge the cell voltage sags under that load. The BMS reads the sag as a cutoff condition and shuts down before the indicator registers empty. It is not a faulty cell — it is the cell reaching its usable floor. After a full charge cycle, the behaviour resets. If cutouts start much earlier than expected after a new cell install, verify the solder joints on the battery connector tabs are not adding resistance to the circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381336244314,"sku":"BWCS-IPSF3SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381336277082,"sku":"BWCS-IPSF3SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381336309850,"sku":"BWCS-IPSF3SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPSF3SL-1.webp?v=1778899987","url":"https:\/\/batteryweb.com\/products\/apple-ipod-ipod-shuffle-3rd-replacement-battery-37v-73mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
