The Motorola PMNN4489D is a genuine IMPRES Li-Ion battery rated at 7.4V and 2900mAh minimum capacity, with an IP68 seal and a UL TIA4950 intrinsic safety approval. It delivers 25+ hours of talk time on an XPR 7000e series radio and is the current factory revision, replacing the PMNN4489, PMNN4489A, PMNN4489B, and PMNN4489C.
It is a drop-in replacement for every earlier PMNN4489 revision. No programming, firmware, or tools required. Belt clip is not included and is ordered separately.

Buyer is responsible for confirming fitment. If you are unsure, send us your radio model number and we will confirm before you order.
PMNN4489 Revision History
Motorola revises accessory part numbers with a trailing letter as manufacturing and component sourcing change. All PMNN4489 revisions share the same form factor, voltage, capacity rating, and certifications, and are mutually interchangeable in compatible radios.
| Revision | Status |
|---|---|
| PMNN4489 | Original release, superseded |
| PMNN4489A | Superseded |
| PMNN4489B / PMNN4489BC | Superseded |
| PMNN4489C | Superseded |
| PMNN4489D | Current factory revision |
If your radio currently uses a PMNN4489A, PMNN4489B, or PMNN4489C, the PMNN4489D is a direct drop-in replacement with no change in performance, fitment, or certification.
What IMPRES Technology Actually Does
IMPRES is a two-way data protocol between the battery and the charger. The battery stores its own usage history in onboard memory. When it is placed in an IMPRES charger, the charger reads that history and adapts the charge cycle to it.
- Automatic reconditioning. The charger decides when the battery needs a full discharge cycle, based on actual use, and performs it without operator intervention.
- End-of-life reporting. The charger reports remaining capacity as a percentage of rated capacity, so you replace batteries on data rather than on guesswork.
- Safe indefinite docking. An IMPRES battery can sit in an IMPRES charger indefinitely without overcharge damage.
- Fleet tracking. Usage data can be read into IMPRES fleet management software for inventory and replacement planning.
The PMNN4489D still charges in a non-IMPRES charger. It will charge and it will work. You simply lose the reconditioning, reporting, and tracking features. The IMPRES benefit only exists when battery and charger both support it.

Intrinsic Safety: What TIA4950 Means Here
The PMNN4489D carries a UL approval to the TIA4950 standard, the current intrinsic safety standard for portable two-way radio equipment. TIA4950 supersedes the older FM approval scheme used on legacy Motorola batteries.
The rating is conditional. An intrinsically safe battery does not make a radio intrinsically safe. The IS approval only applies when a TIA4950-approved battery is used with a radio that is itself IS-rated, and the battery and radio approvals must match. Installing a PMNN4489D in a non-IS radio does not produce an IS-rated assembly, and installing a non-IS battery in an IS radio voids the radio's rating entirely.
Verify the IS label on your radio before deploying into a hazardous location. If the label is missing or illegible, the radio is not approved for that environment.
For users who do not require intrinsic safety, the PMNN4489D is still worth considering over the non-IS PMNN4493: it offers a more robust seal and protection circuit, and the capacity difference between the two is negligible.

Compatible Chargers
To get the IMPRES features described above, pair the PMNN4489D with an IMPRES charger:
- PMPN4576 IMPRES single-unit charger (replaced the PMPN4174/WPLN4232)
- PMPN4284 IMPRES 2 multi-unit charger (backward compatible with IMPRES Gen 1 batteries)

Belt Clip Sold Separately
The PMNN4489D does not include a belt clip. Repeatedly swapping clips between batteries wears the attachment point on the battery housing, so we recommend ordering a clip per battery:
Frequently Asked Questions
Is the PMNN4489D the same as the PMNN4489A?
Functionally, yes. PMNN4489D is the current factory revision of the same battery. It has the same 7.4V / 2900mAh rating, the same IP68 seal, the same UL TIA4950 intrinsic safety approval, and the same physical fitment. It is a direct drop-in replacement for the PMNN4489, PMNN4489A, PMNN4489B, and PMNN4489C.
Will the PMNN4489D fit an XPR 3300e or XPR 3500e?
No. The XPR 3000e series uses a different battery family. Do not attempt to use the PMNN4489D with those radios.
Do I need an IMPRES charger to use this battery?
No. The PMNN4489D charges normally in a standard non-IMPRES charger. You only lose the IMPRES features: adaptive reconditioning, end-of-life capacity reporting, and fleet data tracking. To get those, use an IMPRES charger such as the PMPN4174 or PMPN4284.
Does this battery make my radio intrinsically safe?
No. The battery's TIA4950 approval only applies when it is installed in a radio that is itself IS-rated. An IS battery in a non-IS radio does not create an IS-rated assembly. Check the IS label on your radio before deploying into a hazardous environment.
How long does the PMNN4489D last on a charge?
25+ hours of talk time on an XPR 7000e series radio under Motorola's rated duty cycle. Real-world runtime varies with transmit duty cycle, transmit power, display and GPS use, and ambient temperature.
Is the belt clip included?
No. Belt clips are ordered separately. See the PMLN7008 (2.5 inch) or PMLN4651 (2 inch).
Can the PMNN4489D replace a PMNN4493?
Yes, in most cases. The PMNN4489D offers better sealing and circuit protection, and the rated capacity difference between the two is negligible. Confirm your radio model before substituting.
Is this a genuine Motorola battery?
Yes. This is a Motorola Solutions OEM battery, not an aftermarket equivalent, and it ships new with factory fresh date codes and full Motorola warranty coverage.
