IMPRES™ 2 Single-Unit Desktop Charger (US/NA Plug)

Intelligent Self-Calibration Power System for APX N-Series Radios

The Motorola PMPN4820B is a next-generation IMPRES™ 2 single-unit charger designed specifically for the APX N30 and APX N50 portable radio series. This rapid-rate charging system is engineered to maximize the performance and longevity of your radio fleet through an automated, self-calibrating maintenance protocol. By communicating directly with the battery's internal circuitry, the PMPN4820B eliminates the need for manual battery maintenance, ensuring that every charge cycle is optimized for maximum talk time and an extended overall battery life cycle. The Motorola PMPN4820B is the updated version of the Motorola PMPN4820A and Motorola PMPN4820.

This advanced charger features a sophisticated conditioning system that allows batteries to remain in the pocket for extended periods without the risk of heat damage or overcharging. This "always-ready" capability is critical for emergency responders and professional users who need their equipment fully powered at a moment's notice. The minimalist desktop design incorporates a clear LED indicator light that provides real-time status updates: the light transitions through the charging process and turns a steady yellow when the unit enters its automated reconditioning mode.

The Motorola PMPN4820B is compatible with both Lithium-Ion (Li-ion) and Nickel-Metal Hydride (NiMH) chemistries, providing a versatile power hub for your MOTOTRBO and APX assets. Built with the "Operations Critical" reliability required for mission-critical infrastructure, this charger ensures your APX N-Series radios are always calibrated and ready for the field.

Frequently Asked Questions

• Do I need to manually press a button to recondition the battery? No. The IMPRES 2 system automatically detects when a battery requires reconditioning and starts the process, indicated by a yellow light.
• Is this charger compatible with the original APX 6000 or 8000 series? No. The PMPN4820B is specifically designed for the smaller form factor of the APX N30 and APX N50 batteries.
• Can I leave my radio turned on while it is in the charger? While it will charge, Motorola generally recommends turning the radio off during the charging cycle for the most accurate calibration and fastest charge time.
