Motorola PMNN4573A Rated TIA 4950 IMPRES Battery: PMNN4573

Power compatible Motorola APX and SRX portable radios through demanding shifts with the Motorola PMNN4573A IMPRES 2 battery. This genuine Motorola rechargeable battery combines 4600mAh lithium-ion capacity, intelligent IMPRES 2 technology, rugged IP68 construction, and UL Division 1 HAZLOC certification for approved hazardous-location radio configurations.

The PMNN4573A is designed for public safety, fire and rescue, utilities, petrochemical facilities, manufacturing plants, military operations, and other demanding environments where dependable power and properly certified equipment are essential.

Estimated Battery Runtime

The Motorola PMNN4573A provides approximately 18–19 hours of operating time under a standard 5/5/90 duty cycle:

• 5% transmitting
• 5% receiving
• 90% standby

Runtime is an estimate rather than a guarantee. Actual operating time depends on the radio model, frequency band, transmit power, network coverage, audio volume, GPS, Bluetooth, display use, ambient temperature, battery age, and overall condition.

Compatible Motorola Radios

The PMNN4573A is designed for compatible configurations of the following radios:

• Motorola APX 5000
• Motorola APX 6000
• Motorola APX 6000Li
• Motorola APX 6000XE—supported configurations manufactured after March 2018
• Motorola APX 7000
• Motorola APX 7000XE
• Motorola APX 8000H
• Motorola APX 8000HXE
• Motorola SRX 2200

For hazardous-location use, both the radio and battery must be approved as a certified combination. Installing a HAZLOC battery does not make a standard, non-HAZLOC radio intrinsically safe.

UL Division 1 HAZLOC Rating

The Motorola PMNN4573A is a UL-listed, TIA 4950-compliant Division 1 HAZLOC battery. When attached to a specifically approved Motorola radio, it can support communications in designated hazardous environments where flammable gases, vapors, combustible dust, or ignitable fibers may be present.

Its certification covers approved configurations within:

• Class I hazardous locations involving flammable gases or vapors
• Class II hazardous locations involving combustible dust
• Class III hazardous locations involving ignitable fibers or flyings
• Division 1 environments where hazardous materials may be present during normal operations

The exact classification, groups, temperature code, radio model, and battery revision printed on the equipment must match the requirements of the worksite. Always consult the radio’s safety manual and the authority responsible for workplace safety before entering a hazardous location.

4600mAh High-Capacity Power

With 4600mAh of lithium-ion capacity, the PMNN4573A offers significantly more runtime than standard-capacity APX batteries. It is well suited for long shifts, emergency deployments, remote assignments, and operations where changing batteries frequently is inconvenient or unsafe.

The extended-capacity housing is larger than Motorola’s slim APX batteries, but it provides the additional energy required for longer operating periods.

IMPRES 2 Battery Technology

When used with a compatible Motorola IMPRES 2 charger, the PMNN4573A supports advanced charging and battery-management functions. IMPRES 2 technology can help:

• Optimize each charging cycle
• Provide faster charging with supported IMPRES 2 chargers
• Recondition the battery only when necessary
• Store battery usage and performance information
• Help identify batteries approaching replacement
• Improve long-term fleet management
• Reduce unnecessary spare-battery purchases

Motorola states that IMPRES 2 batteries can provide up to 60% more charging cycles than traditional lithium-ion batteries when properly used with an IMPRES 2 charging system. Supported IMPRES 2 chargers can also charge compatible batteries up to 40% faster than earlier charging systems.

Rugged IP68 Protection

The PMNN4573A carries an IP68 ingress-protection rating, providing strong resistance to dust and water. Motorola’s IMPRES 2 APX battery specifications describe protection against submersion in up to two meters of water for as long as four hours under controlled test conditions.

This durable construction helps protect the battery during:

• Fire and emergency response
• Severe-weather operations
• Utility and infrastructure work
• Industrial plant operations
• Outdoor public-safety assignments
• Military and tactical deployments

The battery must be correctly installed and undamaged to maintain the applicable environmental protection.

Cold-Weather Operation

The PMNN4573A is rated for operation down to approximately -20°C (-4°F) and up to +60°C (+140°F), making it suitable for a wide range of field conditions. As with all lithium-ion batteries, extremely cold temperatures may temporarily reduce available capacity and operating time.

Frequently Asked Questions

How long does the Motorola PMNN4573A last?

The PMNN4573A can provide approximately 18–19 hours of operation under a standard 5/5/90 duty cycle. Heavy transmitting, weak coverage, high audio volume, wireless features, cold temperatures, and battery age can shorten runtime.

Is the PMNN4573A intrinsically safe?

It is a UL Division 1 HAZLOC battery complying with the applicable TIA 4950 standard. However, it may only be used for hazardous-location protection when installed on a Motorola radio specifically approved with this battery and when all required model and revision conditions are met.

Will this battery make my regular APX radio HAZLOC-approved?

No. A HAZLOC battery cannot convert a standard radio into an approved hazardous-location radio. The radio, battery, accessories, and equipment revisions must constitute a certified combination.

Is it compatible with the APX 6000XE?

Yes, but Motorola compatibility information indicates that it is intended for supported APX 6000XE configurations manufactured after March 2018. Verify the radio’s model, serial information, safety approval, and current battery before ordering.

Does it work with the APX 8000?

The battery is primarily intended for hazardous-location models such as the APX 8000H and APX 8000HXE. Confirm compatibility and certification before installing it on any other APX 8000 configuration.

Is the PMNN4573A waterproof?

The battery is IP68-rated and designed to withstand submersion in up to two meters of water for as long as four hours under specified test conditions. IP ratings should not be interpreted as a guarantee against damage in every real-world situation.

Can it be charged in an older IMPRES charger?

IMPRES 2 batteries can generally be charged in compatible IMPRES chargers with the required software. An IMPRES 2 charger is recommended to access the battery’s complete fast-charging, diagnostic, and management capabilities.The PMNN4573A Motorola Battery features IMPRES Technology, (Li-Ion) Lithium Ion, Tall Battery, 4600mAh, IP68 Rated, 5" x 2.34 x 1.57 (HxWxD)
