Important APX 6000 Compatibility Notice

The PMNN4448 does not fit the larger battery platform used by the APX 6000, APX 7000, APX 8000 and SRX 2200. Those radios use batteries such as the PMNN4486, PMNN4487 and PMNN4494.

Always use the Motorola APX battery compatibility chart before moving batteries between different APX radio families.

PMNN4448 Runtime

The PMNN4448 can provide extended operating time compared with lower-capacity batteries in the same physical family.

Motorola documentation has listed approximately:

• Up to 20.5 hours in digital mode on certain MOTOTRBO radios

• Up to 14 hours in analog mode on certain MOTOTRBO radios

• Approximately 12 hours in some radio configurations

• Different operating times on APX radios depending on model, frequency band and programming

Published estimates are normally based on a 5/5/90 duty cycle:

• 5% transmitting

• 5% receiving

• 90% standby

Actual runtime may be reduced by:

• Frequent or extended transmitting

• High transmit-power settings

• Weak signal coverage

• GPS, Bluetooth and wireless features

• Display and backlight use

• High speaker volume

• Connected audio accessories

• Extreme temperatures

• Battery age and accumulated charging cycles

Because the PMNN4448 works with several radio platforms, one runtime figure should not be promised for every application. Testing the battery with your actual radio configuration is the most reliable way to estimate shift coverage.
