Description
IMPRES 2 Single-Unit Desktop Charger Series
Intelligent High-Speed Power Management & Diagnostic Charging Cradle
The Motorola IMPRES 2 Single-Unit Desktop Charger line is a high-performance power management solution engineered to supply optimal energy replenishment to professional handheld transceivers. Integrating this IMPRES 2 charging system into your daily operations allows staging managers, dispatchers, and field technicians to charge mission-critical radio batteries up to 40% faster than legacy charging equipment.
The PMPN4527A is the updated, revised version of legacy chargers like the PMPN4174A, PMPN4174, WPLN4232A, and WPLN4232. Motorola automatically fulfills orders with the latest factory revision, guaranteeing 100% backward physical compatibility while delivering updated charging capabilities across global power standards.
Perfect for emergency dispatch centers, corporate security operations, public works garages, and industrial logistics facilities, this intelligent dock removes the operational headaches of premature battery failure and manual fleet cycle logging. The smart cradle actively communicates with built-in battery microchips to monitor performance degradation, adjust thermal parameters, perform automated calibrations, and extend overall service life. The pocket accommodates standalone spare batteries or fully assembled handheld radios directly, eliminating the need to remove belt clips or carrying cases during charging.

Frequently Asked Questions
What is the relationship between PMPN4527A, PMPN4576A, PMPN4577A, and PMPN4575A?
PMPN4527A is the core IMPRES 2 charger base cradle. PMPN4576A is the US package (PMPN4527A base + 25009297001 US power supply), PMPN4577A is the EU package (PMPN4527A base + PS000037A01 EU power supply), and PMPN4575A is the Brazil package (PMPN4527A base + EPNN9356A Brazil power supply).
Can I charge a battery without attaching it to the radio?
Yes, the charging pocket is mechanically sculpted to receive either a standalone spare battery pack or an entire assembled radio transceiver.
What does a steady amber light on the charger mean?
A steady amber light indicates that the IMPRES 2 circuit has initiated an automated calibration and reconditioning cycle to clear memory effect and restore battery capacity.
Is it safe to leave the radio sitting in the charger overnight?
Yes, once the battery reaches full charge (solid green LED), the smart cradle drops to an energy-efficient trickle maintenance mode to prevent overcharging.
