IMPRES Li-Ion 2900 mAh Battery — Intrinsically Safe & IP68
High-capacity, hazardous-location-rated power for Motorola XPR7, APX, DGP, and XIR series radios.
The Motorola PMNN4489D is a high-performance IMPRES Li-Ion battery designed specifically for use in hazardous environments. UL-rated and TIA4950 certified, it ensures safe and reliable operation in potentially explosive atmospheres. With a 2900 mAh capacity, it provides over 25 hours of talk time when used with an XPR 7000e series radio.
With its IP68 rating, the PMNN4489D is fully submersible at two meters for up to two hours, built for the most demanding field conditions. The PMNN4489D is the current factory revision, replacing the PMNN4489, PMNN4489A, PMNN4489B, and PMNN4489C. It is also a compatible replacement for the Motorola NNTN8560C.

Frequently Asked Questions
What does intrinsically safe mean for this battery?
Intrinsically safe (IS) certification means the PMNN4489D is designed and tested to prevent ignition of flammable gases, vapors, or dust in hazardous locations. The UL and TIA4950 certifications confirm it meets the required safety standards for use in Division 1 and Division 2 hazardous environments such as oil and gas, chemical processing, and mining.
Does the PMNN4489D require an IMPRES charger?
No. The PMNN4489D will charge in any compatible Motorola charger. However, using an IMPRES-compatible charger unlocks automatic adaptive reconditioning, which maximizes talk time and extends the battery's overall cycle life.
What is the difference between the PMNN4489D and earlier revisions?
The PMNN4489D is the current factory revision of the PMNN4489 series. It replaces the PMNN4489, PMNN4489A, PMNN4489B, and PMNN4489C with the same physical dimensions and compatibility, and is a direct drop-in replacement for all prior revisions.
Is the PMNN4489D compatible with non-XPR7 Motorola radios?
Yes. In addition to the XPR7 series, the PMNN4489D is compatible with select APX, DGP, DP, and XIR series radios. Refer to the compatibility table above for the full confirmed model list.
