Motorola PMNN4494A IMPRES 2 Battery – 5100mAh Li-Ion APX Battery

The Motorola PMNN4494A is a high-capacity, genuine Motorola IMPRES 2 lithium-ion battery designed to provide extended operating time for compatible Motorola APX and SRX portable radios. With a rated capacity of 5100mAh, approximately 37.7 watt-hours of energy and an IP68 environmental rating, the PMNN4494 is an excellent choice for public safety, emergency services, utilities, security teams and other radio users who need maximum runtime between charges.

The PMNN4494A is one of the highest-capacity non-HAZLOC OEM batteries available for compatible APX 6000, APX 7000, APX 8000 and SRX 2200 radios. It provides more capacity than both the PMNN4486A and PMNN4487A while retaining Motorola IMPRES 2 battery-management technology.

When used with compatible IMPRES or IMPRES 2 charging equipment, the PMNN4494 can communicate battery information to the charger. This helps optimize charging, track battery condition and support more effective battery-fleet maintenance.

Quick Specifications

What Radios Does the PMNN4494 Fit?

The Motorola PMNN4494A is compatible with the following Motorola portable radios:

• Motorola APX 6000

• Motorola APX 6000 Li

• Motorola APX 6000XE

• Motorola APX 7000

• Motorola APX 7000XE

• Motorola APX 8000

• Motorola APX 8000XE

• Motorola SRX 2200

Motorola’s official compatibility information lists the APX 6000/6000XE, APX 7000/7000XE, APX 8000 and SRX 2200 radio families.

Before ordering, verify the radio’s complete model number, currently installed battery and charging equipment. Customers supporting an APX 6000 fleet can find additional information in our Motorola APX 6000 radio, battery, charger and accessory guide.

Because the PMNN4494 is a tall, high-capacity battery, also verify that any existing carrying case, holster or vehicle charger can accommodate its physical size.

PMNN4494 Runtime

The Motorola PMNN4494A provides up to approximately 21.5 hours of operation under Motorola’s standard 5/5/90 test cycle:

• 5% transmitting

• 5% receiving

• 90% standby

This estimated runtime makes the PMNN4494 especially useful for long shifts, emergency deployments, special events and field operations where charging opportunities are limited.

Actual operating time will vary according to how the radio is used. Factors that can reduce runtime include:

• Frequent or extended transmitting

• High radio transmit power

• Weak system coverage

• GPS and wireless features

• Display and backlight use

• Connected audio accessories

• Extremely hot or cold temperatures

• Battery age and accumulated charging cycles

A battery may still indicate a full charge while providing less operating time as it ages. Batteries that can no longer support the required shift should be evaluated and replaced before they create operational downtime.

Compatible Chargers

The PMNN4494A should be charged with a compatible Motorola APX charger or a properly designed replacement charger. Available charging options include:

• Motorola NNTN8860A: IMPRES 2 single-unit charger for an individual radio or battery

• Motorola NNTN8844A: IMPRES 2 six-unit charger with individual displays

• Motorola NNTN7624B: IMPRES 2 single-unit vehicular charger

• Motorola RLN6434B: APX travel charger

• CTC-1-APX: Cost-effective replacement single-unit APX charger

• CTCM-6-APX: Six-position replacement charger for radio fleets

• CTCM-10-APX: Ten-position replacement charger for high-volume applications

IMPRES 2 batteries can be used with appropriate Motorola IMPRES chargers, although older chargers may require current software. An IMPRES 2 charger is recommended for the most complete charging, diagnostic and battery-management capabilities.

A charger that physically accepts the battery is not automatically the correct charger. Always verify the charger model, charging pocket and battery chemistry before use.

PMNN4494 vs PMNN4486

The PMNN4494 provides approximately 50% more rated capacity than the 3400mAh Motorola PMNN4486A. It is the better choice when extended operating time is more important than minimizing battery size.

The PMNN4486 is a strong everyday battery for users who prefer a lower-profile radio configuration and do not require the PMNN4494’s maximum capacity.

PMNN4494 vs PMNN4487

The PMNN4494 provides 250mAh more rated capacity than the PMNN4487. This is an increase of approximately 5%, so the actual runtime difference may be relatively modest.

Choose the PMNN4494 when obtaining the highest available capacity is the main priority. Choose the PMNN4487 when its 4850mAh capacity is sufficient and it offers a more attractive purchase price.

Both batteries are high-capacity, IP68-rated, non-HAZLOC IMPRES 2 batteries for compatible Motorola APX and SRX radios.

Previous and Superseded Motorola Part Numbers

PMNN4494 is the base Motorola part number, while PMNN4494A identifies the current product revision commonly supplied.

• PMNN4494: Base part number

• PMNN4494A: Current revision

Unlike the PMNN4487A, which Motorola identifies as the current replacement for NNTN7034B, the PMNN4494A is primarily a higher-capacity battery option. Motorola does not consistently identify it as the direct superseding number for one specific older battery.

The PMNN4494 may be selected as a capacity upgrade from compatible older APX batteries, including lower-capacity models. However, physical compatibility does not make every battery a direct equivalent. Capacity, size, charger compatibility, IMPRES generation, environmental rating and safety certification must all be considered.

OEM vs Replacement PMNN4494 Battery Options

Motorola OEM PMNN4494A

The genuine Motorola PMNN4494A provides:

• Motorola IMPRES 2 communication

• Published 5100mAh capacity

• Approximately 37.7Wh of energy

• IP68 environmental protection

• OEM fit and construction

• Compatibility with approved Motorola APX chargers

• Motorola warranty coverage

• Support for compatible IMPRES battery-management features

The OEM PMNN4494 is generally the preferred choice for public-safety agencies, government departments and organizations that require manufacturer-original equipment or standardized Motorola fleet-management support.

Replacement PMNN4494 Batteries

A quality aftermarket battery may offer similar or greater rated capacity at a lower cost. Replacement batteries can be useful for commercial fleets, backup inventory and organizations seeking to reduce battery-replacement expenses.

Before selecting a replacement PMNN4494 battery, compare:

• Rated capacity

• Nominal voltage

• Watt-hours

• Cell manufacturer and quality

• Smart or IMPRES-compatible communication

• Charger compatibility

• IP or environmental rating

• Operating-temperature range

• HAZLOC certification

• Warranty length

• Manufacturer reputation

A replacement battery described as “smart,” “IMPRES compatible” or “replaces PMNN4494” should not automatically be assumed to provide every function of a genuine Motorola IMPRES 2 battery.

If your agency requires OEM equipment, IMPRES fleet-management data, Motorola warranty coverage or a specific safety certification, verify those requirements before ordering an aftermarket alternative.
