It fits directly into the PMD-R2 battery compartment and restores full recording and playback operation. No OEM part number is published for this cell — fitment is confirmed against the PMD-R2 chassis and connector.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePMD-R2 fitment:\u003c\/strong\u003e\n    The PMD-R2 runs a single-cell 3.7V Li-ion platform. This cell matches that voltage rail and the physical bay dimensions (71.00 × 19.70 × 19.70mm), so the BMS in the recorder reads charge state 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 charge and discharge on the bench and confirmed the BMS accepted the cell, reported charge state correctly, and did not trigger a protection cutoff at normal recording draw levels.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the PMD-R2:\u003c\/strong\u003e\n    Run the first full charge inside the recorder itself, not an external charger. The PMD-R2 BMS calibrates its fuel gauge against the cell during that first in-body charge cycle — skipping this step can cause the battery indicator to misread remaining capacity from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePMD-R2 battery indicator stuck at full or dropping suddenly to empty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PMD-R2 maps its battery display to voltage thresholds set during the first charge cycle. A new cell that was not initialised in-body will feed the BMS a discharge curve that doesn't match those thresholds. The result is a gauge that reads 100% far too long, then falls sharply. Run one full in-body charge cycle from flat to full, and the gauge recalibrates to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePMD-R2 powering off mid-recording with charge still showing on display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS undervoltage cutoff, not a dead cell. Under recording load — especially with active input monitoring and the backlit display — current draw spikes briefly above what a heavily aged or partially discharged cell can deliver without voltage sag. The BMS reads that voltage drop as a fault and shuts the unit down protectively. Charge the cell fully and confirm resting voltage is at or above 4.1V before starting a long recording session. If the cutoff repeats on a full charge, the cell has lost capacity and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333919146074,"sku":"BWCS-NB111-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333919178842,"sku":"BWCS-NB111-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333919211610,"sku":"BWCS-NB111-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NB111-1.webp?v=1778213576","url":"https:\/\/batteryweb.com\/products\/pioneer-pmd-r2-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
