This patented Motorola technology for two-way radio power combines a "smart" battery, a "smart" charger, and a system that lets the battery, charger and other accessory devices communicate over a singlewire.

The battery itself has the intelligence to store information such as elapsed usage time, charge and discharge current, voltage and temperature. The charger then uses the battery information to control battery mainte-nance automatically.

So the impres system automatically manages battery reconditioning and gauges fuel use to extend battery pack life, extend talk time and improve performance. This innovative, intelligent technology helps to make sure your two-way radios are working when you need them most: in high-risk public safety applications, remote field operations and anytime reliable operation is critical.

The impres system works with nickel-cad-mium, nickel-metal hydride and lithium-ion batteries.
