Description
Motorola PMDN4080AR 12V DC Portable Radio Battery Eliminator
Genuine Motorola Solutions Original DC power adapter interconnecting portable radios to 12V vehicular and benchtop power sources.
The Motorola PMDN4080AR is an authentic original equipment manufacturer (OEM) portable radio battery eliminator engineered to provide continuous, uninterrupted power to compatible Motorola two-way radios. Designed for security consoles, dispatch desks, heavy construction equipment, delivery vans, and commercial fleet vehicles, this adapter replaces the standard rechargeable battery pack and connects the radio directly to a 12V DC auxiliary vehicle socket or regulated power supply. Sourced directly from our verified inventory of Motorola Two-Way Radios & Accessories, the PMDN4080AR eliminates battery charging cycles and operational downtime during round-the-clock shifts.
Engineered with an internal regulated DC-DC power conversion module, the Motorola PMDN4080AR accepts variable automotive input voltages ranging from 10.8V to 16.0V DC and steps them down to a regulated 7.5V DC supply matching the exact operating characteristics of the radio's native battery chemistry. In compliance with vehicular electrical transients and alternator noise mitigation under SAE Standards (SAE J1455) and industrial safety criteria under UL Standards (UL 62368-1), the circuit features integrated overvoltage clamping, reverse-polarity protection, and noise filtration chokes to prevent alternator whine from distorting transmitted voice. Built to endure severe mechanical vibration and continuous physical flexing in accordance with DoD Standards (MIL-STD-810H), the heavy-duty coiled cable stretches for flexible in-cab positioning without pulling loose from the chassis. Meeting workplace safety requirements under OSHA Standards, the eliminator preserves battery longevity by preventing continuous overcharging in vehicles while ensuring your radios remain active.
Key Features & Benefits
-
Continuous 24/7 Radio Power: Replaces standard rechargeable batteries, enabling continuous operation in stationary dispatch setups, cranes, and fleet vehicles without swapping packs.
-
Stabilized 7.5V DC Step-Down Output: Internal voltage regulator safely steps down 12V/13.8V vehicle power to the precise 7.5V DC nominal voltage required by the radio.
-
Built-in Electrical Protection: Features an inline fuse, reverse polarity safeguards, and overvoltage suppression diodes to shield sensitive radio transceivers from vehicle power surges.
-
Integrated Alternator Noise Suppression: Filtered circuit topology removes RF hum, engine alternator whine, and ignition buzz from both transmit and receive audio.
-
Heavy-Duty Coiled Cable: Industrial coiled power cord with molded strain relief extends for convenient radio handling and retracts cleanly to reduce cab clutter.
-
Drop-In Chassis Rail Alignment: Precision molded dummy battery housing slides and locks securely onto the radio's native battery guide rails with positive mechanical retention.
-
Gold-Plated Contact Terminals: Corrosion-resistant power contacts deliver reliable electrical conductivity over years of intensive field service.

Frequently Asked Questions
What is the function of a battery eliminator?
A battery eliminator slides and locks onto the back of a portable two-way radio in place of the standard rechargeable battery. By drawing power directly from an external 12V vehicle battery or DC bench power supply, it allows the radio to operate continuously without relying on battery cells that degrade over time from heat or continuous trickle charging.
What does the "AR" suffix signify on the PMDN4080AR part number?
In Motorola Solutions catalog nomenclature, the trailing suffix "AR" indicates an authentic accessory replacement unit. Part numbers cataloged as PMDN4080, PMDN4080A, or PMDN4080AR represent the same physical form factor, voltage step-down rating, and radio chassis compatibility.
Does this unit charge a battery while connected?
No. The PMDN4080AR contains no internal battery cells and does not charge external batteries. It is a solid-state dummy battery adapter designed strictly to deliver regulated continuous DC power directly to the radio transceiver.
Can I use this battery eliminator in a 24V commercial vehicle?
No. The PMDN4080AR is designed for standard 12V DC electrical systems (operating across 10.8V to 16.0V DC). Connecting it directly into a 24V commercial vehicle or heavy haul truck power port without an external 24V-to-12V step-down converter will blow the internal fuse and can damage the regulator.
Is the power cable fused?
Yes. The 12V DC vehicle adapter plug contains a user-serviceable fast-acting fuse engineered to isolate the radio and vehicle wiring harness in the event of an electrical short or heavy power spike.
Warranty
1-year manufacturer’s replacement warranty.
