Motorola APX radios do not all use the same battery. The correct choice depends on the exact radio model, battery platform, charger, radio configuration and—when applicable—hazardous-location approval. This Motorola APX battery compatibility chart helps you identify the correct battery family before comparing capacity, runtime or price.
Important: Always check the complete model number on the radio and the part number printed on the original battery. Physical fit alone does not prove that a battery is approved for a particular radio configuration. If your radio is used in a hazardous location, use only a radio-and-battery combination approved for that environment.

Actual operating time can be shorter or longer. Transmit frequency, signal strength, power level, GPS, Bluetooth, Wi-Fi, display use, speaker volume, temperature and battery age all affect runtime. For selection advice rather than fitment data, read our APX battery runtime and buying guide.
Compatibility by Motorola Battery Part Number
PMNN4485: Lightweight IMPRES 2 Option
The PMNN4485 is a 2550 mAh IMPRES 2 lithium-ion battery for compatible full-size APX radios. Its lower capacity is balanced by a shorter, lighter profile. It is a practical choice for routine shifts, users with easy charger access and departments that prioritize carry weight. Compare the PMNN4485 smart replacement battery.
PMNN4486: Balanced Everyday Capacity
The PMNN4486 is a 3400 mAh IMPRES 2 lithium-ion battery rated IP68. Motorola lists approximately 15.5 hours of operation under its standard test cycle. It is often the most balanced option for users who want more runtime without moving to the largest battery profile. View the OEM Motorola PMNN4486A, the PMNN4486 smart replacement battery or the high-capacity PMNN4486 replacement.
PMNN4487 and NNTN7034B: Extended Runtime
The PMNN4487 is a 4850 mAh IMPRES 2 battery with a published approximate operating time of 21 hours under the standard duty cycle. It is suited to long shifts, emergency operations and teams with limited access to chargers. The NNTN7034B is a commonly searched earlier part number associated with this battery family. View the Motorola NNTN7034B battery.
PMNN4494: Maximum Capacity
The PMNN4494 provides 5100 mAh and approximately 21.5 hours under Motorola’s standard test cycle. It is designed for compatible users who place maximum runtime ahead of reduced size and weight. View the Motorola PMNN4494A IMPRES 2 battery.
PMNN4493: Compact APX Platform
The PMNN4493 is a 3000 mAh IMPRES lithium-ion battery listed for compatible compact APX platforms, including APX 900, APX 1000, APX 3000 and APX 4000 applications. It is not a substitute for the PMNN4485/4486/4487/4494 family. View the Motorola PMNN4493A battery.
Why an APX Radio May Display “Wrong Battery”
A battery can attach to a radio yet still trigger a warning. Common causes include:
- The battery belongs to a different APX platform.
- The radio is programmed for a hazardous-location battery and detects a different approval type.
- A standard battery is being used with a configuration that requires a specific approved battery.
- The battery’s smart data is unsupported or cannot be read correctly.
- The radio firmware or programming needs to be reviewed by a qualified radio technician.
Do not ignore a battery warning on a radio deployed in a safety-sensitive or hazardous environment. Confirm the approved configuration before returning it to service.
IMPRES and IMPRES 2 Compatibility
IMPRES batteries communicate data to compatible Motorola chargers, helping automate charging, conditioning and battery management. IMPRES 2 expands those capabilities with faster charging on supported equipment, improved diagnostics and longer potential service life. Motorola states that IMPRES 2 batteries used with IMPRES 2 chargers can deliver up to 60% more charging cycles than traditional lithium-ion batteries.
An IMPRES 2 battery may charge in an earlier compatible IMPRES charger, but the fleet may not receive every IMPRES 2 feature. Learn how the system works in our Motorola IMPRES complete guide.
Frequently Asked APX Battery Compatibility Questions
Do all Motorola APX batteries fit every APX radio?
No. “APX” describes a broad radio family, not one universal battery platform. Compact APX radios, full-size APX radios, specialized hazardous-location models and APX NEXT radios can use different batteries.
What battery fits the Motorola APX 6000?
Common non-hazardous IMPRES 2 options include PMNN4485, PMNN4486, PMNN4487 and PMNN4494. Verify the complete radio configuration before ordering, especially for certified hazardous-location use. See the Motorola APX 6000 complete guide.
What battery fits the Motorola APX 1000?
The APX 1000 uses the compact APX battery platform. Motorola listings include options such as NNTN8128, PMNN4424, PMNN4448 and PMNN4493, depending on the configuration and required approval. See our APX 1000 battery guide.
Can an APX 3000 battery be used on an APX 6000?
No. The APX 3000 battery and charger platform does not interchange with the APX 6000, APX 7000 and APX 8000 battery platform.
Can I use an aftermarket APX battery?
A reputable replacement can be appropriate for general use when it is designed for the exact radio and charger and provides the required smart features, environmental protection and warranty. Do not assume an aftermarket battery preserves a hazardous-location approval. Verify the approved radio-and-battery combination first.
How do I identify my current APX battery?
Remove the battery from the radio and read the label on its back. Record the complete part number, capacity, chemistry and certification markings. Also record the radio model and charger number before selecting a replacement.
Confirm Your Battery Before Ordering
The safest process is simple: match the exact radio model, current battery part number, charger and operating environment. Once compatibility is confirmed, compare capacity, weight, IMPRES functionality, IP rating, warranty and price.
If you are uncertain, contact Battery Distributors before ordering. Send us the radio model, number printed on the existing battery, charger model and any hazardous-location requirement, and we will help identify the appropriate options.
Compatibility information is provided as a purchasing aid. Motorola product offerings and approved configurations can change. Always follow the current manufacturer documentation and your organization’s safety requirements.
