It replaces part number W10-VA0099 and fits the compact cell bay on the DMP-3 directly. The original cell in these players degrades with shallow-cycle use over time, leaving the device unable to hold a charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDMP-3 fit:\u003c\/strong\u003e The DMP-3 runs a single-cell 3.7V Li-ion configuration with a fixed connector and BMS handshake tied to cell voltage. This replacement matches the cell dimensions (52.96 × 33.03 × 7.17mm), voltage curve, and protection circuit the player expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran the cell through charge and discharge cycles on the DMP-3 platform. The BMS accepted the cell without fault flags, and the protection circuit responded correctly at low-voltage cutoff — no false trips during normal audio playback draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charging on the DMP-3:\u003c\/strong\u003e After fitting a new cell, connect the DMP-3 to its charger before powering on. If the original battery discharged completely during storage, the player may sit in deep discharge protection and appear dead. Leave it on charge for at least 30 minutes before attempting to boot.\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 DMP-3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DMP-3 tracks battery level using voltage thresholds mapped to the original cell's discharge curve. When a new cell is installed, the player's internal gauge has no reference point for the new cell's resting voltage. This causes the percentage display to jump — sometimes showing full, then dropping sharply after a few minutes of playback. Run two full charge-to-cutoff cycles and the gauge will recalibrate to the new cell's actual curve.\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 DMP-3 draws a brief current spike when driving the headphone output at moderate to high volume. Near the bottom of the cell's discharge curve, voltage sags under that load and drops below the amplifier's minimum operating point — even when the battery indicator still shows a bar or two remaining. This is a voltage sag issue, not a capacity issue. If playback drops out abruptly at low charge, reduce playback volume slightly to lower the current draw, or charge the device before the indicator falls below one bar.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381336637530,"sku":"BWCS-DMP3SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381336670298,"sku":"BWCS-DMP3SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381336703066,"sku":"BWCS-DMP3SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DMP3SL_1.webp?v=1778899987","url":"https:\/\/batteryweb.com\/products\/minon-dmp-3-replacement-battery-37v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
