Motorola PMNN4487A IMPRES 2 High-Capacity APX Radio Battery – 4850mAh, IP68

The Motorola PMNN4487A is a genuine Motorola IMPRES 2 high-capacity lithium-ion battery designed for compatible Motorola APX portable radios. With 4850mAh capacity, rugged IP68 protection, and approximately 21 hours of operating time under Motorola's standardized 5/5/90 duty-cycle testing, the PMNN4487 is an excellent choice for public safety, emergency response, utilities, industrial operations and other users who need extended radio runtime between charges. 

Compared with shorter standard-capacity APX batteries, the PMNN4487 provides substantially more capacity for long shifts and demanding field use. It is especially useful when personnel cannot easily return to a charger or change batteries during an assignment.

Motorola PMNN4487 Specifications

*Motorola's approximately 21-hour figure is based on a 5/5/90 duty cycle. Actual operating time varies according to radio configuration, transmit activity, signal conditions, transmit power, GPS/Bluetooth use, audio volume, temperature, accessories and battery age.

Compatible Motorola Radios

The Motorola PMNN4487 is designed for compatible full-size Motorola APX portable radios, including:

• Motorola APX 6000
• Motorola APX 6000XE
• Motorola APX 7000
• Motorola APX 7000XE
• Motorola APX 8000
• Motorola SRX 2200

Motorola's APX documentation identifies PMNN4487 among the compatible IMPRES 2 batteries for these APX/SRX platforms. Radio versions and regional configurations can vary, so confirm the exact radio model and existing battery part number before ordering.

4850mAh High-Capacity Performance

The PMNN4487 provides 4850mAh of rechargeable Li-Ion capacity, making it one of Motorola's higher-capacity battery choices for compatible APX radios.

Motorola lists approximately 21 hours of operating time using a 5/5/90 duty cycle. 

The additional capacity makes the PMNN4487 particularly well suited for:

• 12-hour and extended shifts
• Police, fire and EMS operations
• Emergency and disaster response
• Utility and public-works crews
• Remote field assignments
• High radio-traffic environments
• Cold-weather operations
• Personnel who cannot conveniently change batteries during a shift

The PMNN4487 is also rated for operation down to approximately -30°C, compared with -20°C for several shorter APX batteries in Motorola's current accessory documentation.

IMPRES 2 Battery Technology

The PMNN4487 incorporates Motorola IMPRES 2 intelligent battery technology.

When IMPRES 2 batteries are paired with compatible IMPRES 2 chargers, Motorola states that the system can deliver up to 60% more charging cycles than traditional lithium-ion batteries. IMPRES 2 technology is designed to help optimize charging and battery management for professional radio fleets. 

This makes the PMNN4487 particularly attractive for organizations operating large APX fleets where battery reliability, service life and battery management are important.

Compatible Motorola IMPRES 2 Chargers

Motorola's IMPRES 2 APX documentation identifies these charger families for the compatible APX platform:

NNTN8860 – IMPRES 2 Single-Unit Charger, 115 VAC

NNTN8863 – IMPRES 2 Single-Unit Charger, 100–240 VAC

NNTN8844 – IMPRES 2 Multi-Unit Charger

Motorola also states that IMPRES 2 batteries retain compatibility with existing IMPRES chargers, although pairing them with IMPRES 2 charging equipment provides the full IMPRES 2 battery-management benefits.

PMNN4487 vs PMNN4486 vs PMNN4494

Choosing among these three popular Motorola IMPRES 2 batteries largely comes down to the balance between battery size and runtime.

*Approximate Motorola operating time at a 5/5/90 duty cycle. 

PMNN4487 vs PMNN4486

The PMNN4486 is a 3400mAh IMPRES 2 battery with Motorola-listed runtime of approximately 15.5 hours. The PMNN4487 increases capacity to 4850mAh and Motorola-listed runtime to approximately 21 hours. 

Choose the PMNN4486 when a smaller battery profile and lower weight are priorities.

Choose the PMNN4487 when extended operating time is more important than battery size and weight.

PMNN4487 vs PMNN4494

The PMNN4494 provides 5100mAh capacity and approximately 21.5 hours of Motorola-listed operating time, compared with 4850mAh and approximately 21 hours for the PMNN4487. 

The difference in Motorola's standardized runtime estimate is therefore relatively small. Buyers should consider price, availability, radio configuration and their specific operating requirements when choosing between these two high-capacity options.

PMNN4487 vs Standard-Capacity APX Batteries

For users working shorter or predictable shifts, a lower-capacity battery such as the PMNN4485 (2550mAh) or PMNN4486 (3400mAh) may provide adequate runtime with a smaller battery profile.

The PMNN4487 makes more sense when maximizing time away from the charger is the priority.

BatteryDistributors' APX 6000 guide currently positions the PMNN4487 as the extended-runtime option, with the PMNN4494 representing the maximum-capacity choice in that group. Battery Distributors

Rugged IP68 Protection

The PMNN4487 carries Motorola's IP68 rugged rating. Motorola states that its IMPRES 2 batteries share the APX radio family's IP68 protection and can withstand complete submersion in up to two meters of water for as long as four hours under specified test conditions. 

This rugged construction makes the PMNN4487 well suited for public-safety and professional users working around rain, dust, dirt and demanding field environments.

IP68 protection should not be confused with hazardous-location certification.

Important HAZLOC Notice

The standard PMNN4487 is not listed as a hazardous-location-certified battery in Motorola's IMPRES 2 APX battery compatibility table. 

Users operating around flammable gases, vapors, fuels or combustible materials should select a radio-and-battery combination carrying the appropriate hazardous-location certification for their application.

Do not assume that an IP68 rating means HAZLOC approval. They address different requirements.

For applicable hazardous-location configurations, consult the radio documentation and select the appropriate certified Motorola battery.

Why Choose the Motorola PMNN4487?

The PMNN4487 is a strong choice for APX users who want:
