It fits the full L Player range sharing OEM part number 8D05N13849. Capacity matches the factory specification at 2.78Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eL Player family compatibility:\u003c\/strong\u003e\n    The 2GB, 4GB, 8GB, and 1LP8WHT models all run the same voltage rail and use an identical connector footprint, which is why they share one battery part number across the lineup.\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 L Player platform. The BMS accepted the new cell without error flags, and charge termination occurred cleanly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install charge cycle:\u003c\/strong\u003e\n    If the player shows no response after fitting this battery, connect the original charger and leave it for 30 minutes before attempting to power on. Cells shipped at storage charge can sit below the device's minimum startup threshold, and the charger must deliver a trickle current first to bring the voltage up before the firmware will boot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eL Player not waking after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells lose roughly 5–8% charge per month in storage. An L Player left unused for six months or more can arrive at a voltage so low the protection circuit locks the cell out entirely. The device will show nothing on screen — no charge indicator, no backlight. Connect the charger and wait. Most BMS circuits in this class begin accepting trickle current at around 2.5V and will unlock normal charging once the cell climbs past 3.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe L Player reads remaining charge by measuring cell voltage against a fixed lookup table stored in firmware. A new cell has a slightly different internal resistance profile than the aged one it replaced, so the voltage readings at mid-charge won't match the expected curve. The percentage display will jump — sometimes 20–30 points — during the first few cycles. Run two or three full charge-to-discharge cycles and the indicator will recalibrate to the new cell's actual discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381349515354,"sku":"BWCS-IRL2SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381349548122,"sku":"BWCS-IRL2SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381349580890,"sku":"BWCS-IRL2SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRL2SL-1.webp?v=1778900059","url":"https:\/\/batteryweb.com\/products\/iriver-l-player-2gb-replacement-battery-37v-750mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
