It drops into the same battery bay using the original latch and contact strip. Voltage and capacity match OEM spec — 7.4V nominal, 3350mAh, 24.79Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMotoTRBO DR3000 \/ DP3400 \/ DP3600 platform fit:\u003c\/strong\u003e\n    These models share a common 7.4V Li-ion bay format, a standardised gold contact strip, and the same BMS handshake protocol — which is why one part number family covers all of them. Swapping between models in this series does not require a charger change.\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 body through transmit and receive loads. The BMS held its overcurrent cutoff threshold correctly on PTT spikes and accepted a full charge cycle on the standard Motorola IMPRES and non-IMPRES docks without fault LED.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the charger dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on the first seating, remove the battery and wipe the gold contact strip with a dry cloth. Reseat firmly — the MotoTRBO platform runs a contact-integrity check before it accepts the BMS handshake and begins charging. A marginal contact on the first cycle is the most common reason a new pack appears rejected.\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\n  \u003cp class=\"bpw-desc-p\"\u003ePressing PTT on the DR3000 draws a sharp current spike as the RF power amplifier ramps to full output. If the replacement pack's BMS has a low overcurrent threshold — or if the cells are sitting at storage voltage rather than a full charge — the BMS can trip that cutoff and kill transmission instantly. This is not a radio fault; it is the pack protecting itself against what it reads as an overload. Fully charge the battery before the first operational use and confirm terminal voltage is at or above 8.2V before deployment. A pack at storage voltage (typically around 7.5–7.6V) is more likely to trip on transmit start than one at full charge.\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 and DP3400 series use a simple voltage-threshold bar display — each bar corresponds to a voltage band, not a calculated capacity reading. A new pack shipped at storage voltage will sit in a lower voltage band and display one or two bars even though the cells are healthy. This is not a faulty pack. Run one full charge cycle on an IMPRES or standard Motorola dock and allow the charge to complete fully. After that cycle, terminal voltage will sit at approximately 8.35–8.4V and the indicator will read the correct full-charge bar count.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426228371546,"sku":"BWCS-MTX630TC-1","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426228404314,"sku":"BWCS-MTX630TC-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426228437082,"sku":"BWCS-MTX630TC-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTX630TC-1.webp?v=1779930523","url":"https:\/\/batteryweb.com\/products\/motorola-mototrbo-dr3000-replacement-battery-74v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
