It also fits the DP3400, DP3401, and DP3600 series, which share the same voltage rail, connector format, and BMS handshake protocol. Capacity is sourced from product data at 2600mAh (19.24Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDR3000 \/ DP3000 series compatibility:\u003c\/strong\u003e\n    The DR3000, DP3400, DP3401, and DP3600 all run the same 7.4V Li-ion architecture with a matched connector and identical BMS communication protocol. One replacement pack covers the entire platform without adapters or modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a DR3000 unit through full transmit-receive sequences. The BMS held steady through repeated PTT bursts, managing the transmit current spike without tripping overcurrent protection or dropping the radio into low-power mode.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on a Motorola dock:\u003c\/strong\u003e\n    If the charger dock shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The Motorola platform requires a clean contact cycle to complete the BMS handshake before charging can begin.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DR3000 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.7V per cell, well below the 4.2V full-charge peak. Under transmit load, that reduced cell voltage sags further, and the radio's BMS can interpret the drop as an overcurrent event. The result is an abrupt cutout mid-PTT, not a hardware fault. Dock the battery and allow a full charge cycle to reach 8.4V before field use. Once fully charged, the voltage headroom prevents sag-triggered cutoffs during sustained RF output.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected on a new PMNN4065\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DR3000 reads battery level through voltage thresholds — each bar corresponds to a voltage range. A new pack at storage voltage sits in the lower threshold bracket, so the indicator displays one or two bars even though the cell is not depleted. This is not a capacity fault. After one full charge cycle to 8.4V, the indicator will display the correct level. If it still reads low after a full charge, check that the gold contacts are seated cleanly against the dock terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426329296986,"sku":"BWCS-MTX640TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426329329754,"sku":"BWCS-MTX640TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426329362522,"sku":"BWCS-MTX640TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTX640TW-1.webp?v=1779930785","url":"https:\/\/batteryweb.com\/products\/motorola-mototrbo-dr3000-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
