Why Professionals Choose the Motorola Battery PMNN4544A
Fleet managers running XPR 3000 or XPR 7000 series radios face one recurring problem. When a battery starts losing capacity mid-shift, the team either rotates to a spare or the operator continues on a reduced-capacity battery. The root cause: standard Li-Ion batteries have no on-device indicator of remaining capacity health — the call comes down to guesswork or a separate battery analyzer. IMPRES removes that variable.
Note: PMNN4544A is the current production version.It replaced the earlier PMNN4409.
When the PMNN4544A is used with a Motorola IMPRES charger, the charger reads data stored in the battery's onboard memory and applies an adaptive charge cycle — adjusting for the battery's actual condition rather than running a fixed profile. Capacity health is tracked and displayed on IMPRES chargers, and the system automatically triggers reconditioning when the battery falls below performance thresholds. For a fleet of 20 or more radios, this eliminates manual battery testing and reduces unplanned replacements.
The PMNN4544A delivers 2450 mAh at 7.4V with an energy rating of 18.1 Wh — a capacity increase over the PMNN4409 (2250 mAh) without a change in physical size or weight. The IP68 rating means the battery housing withstands full submersion, consistent with the XPR radio body's own IP rating. The battery is not intrinsically safe rated and is not approved for use in classified hazardous locations.

Does the PMNN4544A require an IMPRES charger to function?
The PMNN4544A charges in any compatible Motorola charger. However, the full IMPRES benefit — automatic adaptive reconditioning, end-of-life display, capacity tracking, and the 18-month extended warranty — is only available when the battery is used exclusively with a Motorola IMPRES charger. With a standard charger, the battery operates normally but warranty coverage defaults to 12 months and automatic maintenance is not active.
Is this an original Motorola battery or an aftermarket product?
The PMNN4544A listed here is an original Motorola Solutions OEM battery — not an aftermarket or third-party replacement. AXDIGITAL is an authorized Motorola Solutions dealer in the USA. The PMNN4544A carries Motorola's 18-month IMPRES performance warranty (when used with IMPRES chargers) and a 24-month workmanship warranty.
