It matches OEM part numbers P11R06-01-S01 and IA1A803B1. Fit the battery when the original no longer holds a charge or the player fails to power on.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMEV30 and MEV60 shared battery platform:\u003c\/strong\u003e\n    Both models run off the same 3.7V cell with identical connector pinout and BMS voltage thresholds. One replacement covers either unit 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 the Gigabeat charge circuit and confirmed the BMS accepted full charge current without triggering a protection cutoff. Discharge curve held flat through the mid-range before the expected voltage drop near depletion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap wake-up procedure:\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 pressing power. Cells stored or shipped at low state of charge can sit below the device's minimum wake threshold and need a slow trickle before the main charge circuit engages.\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 fitting a new cell in the MEV30\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Gigabeat MEV30 uses a voltage-threshold method to estimate charge level — it does not have a coulomb counter. After a cell swap, the firmware's reference points no longer match the new cell's actual discharge curve. The percentage reading can jump 10–20% in either direction during the first few charge cycles. Run two or three full charge-to-depletion cycles and the display will stabilise against the new cell's voltage profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the battery indicator shows empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe audio amplifier in the MEV30 draws a short current spike when driving headphones at higher volume. Near the end of discharge, the cell's internal resistance rises and that spike causes a brief voltage sag below the BMS cutoff threshold — the player shuts down even though the indicator still shows some charge remaining. This is a cell chemistry behaviour, not a fault with the replacement. Lowering playback volume by 15–20% during the final portion of a charge cycle avoids triggering the cutoff early.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381343584346,"sku":"BWCS-TS003SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381343617114,"sku":"BWCS-TS003SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381343649882,"sku":"BWCS-TS003SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TS003SL-1.webp?v=1778900081","url":"https:\/\/batteryweb.com\/products\/toshiba-gigabeat-mev30-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
