PMNN4846A Specifications

Important Compatibility Information

The PMNN4846A is a speaker-microphone battery—not a two-way radio battery. It attaches to and powers the WM800 wireless microphone. It does not mount directly onto an APX radio.

When the WM800 microphone has the required radio firmware and programming, it can be used with supported equipment from radio families such as:

• Motorola APX NEXT
• Motorola APX N70
• Motorola APX N50
• Motorola APX N30
• Select Motorola APX portable radios
• Select Motorola APX mobile radios
• Motorola SRX 2200 configurations

Radio compatibility is determined by the WM800 microphone, radio hardware, Bluetooth support, firmware and agency programming. The PMNN4846A’s direct physical compatibility is with the WM800 microphone itself.

Built for Demanding Environments

The PMNN4846A carries an IP68 rating, matching the WM800’s emphasis on rugged public-safety operation. This rating provides protection from dust and water exposure under Motorola’s specified testing conditions.

Its UL Division 2 compliance supports properly approved hazardous-location configurations where flammable gases, vapors or liquids are not normally present in ignitable concentrations but could appear under abnormal conditions.

PMNN4846A Charging Options

The PMNN4846A can be charged while installed on compatible WM800 equipment using approved charging accessories. The WM800 supports USB-C charging, while Motorola also offers a compatible dual-position desktop charging solution.

The Motorola PMPN4653A desktop charging tray can charge a WM800 microphone and a spare PMNN4846A battery, helping agencies prepare two power sources for the next shift.

For reliable operation, use only a charger specifically listed for the Motorola WM800 and PMNN4846A battery.

Why Keep a Spare PMNN4846A Battery?

Wireless speaker microphones require their own power source. If the WM800 battery becomes depleted, the radio may remain operational, but the user can lose convenient wireless access to the microphone’s speaker, push-to-talk and emergency controls.

Keeping a charged PMNN4846A available provides several advantages:

• Reduces WM800 downtime
• Enables fast field battery replacement
• Supports back-to-back shifts
• Simplifies fleet battery rotation
• Provides backup power during emergencies
• Avoids waiting for the microphone to recharge

Battery runtime varies according to transmit activity, received-audio volume, Bluetooth conditions, temperature, battery age and frequency of control use.
