Discovery 640/645: Talk Time and Battery Use

Article ID :
000004983
Discovery 640: The Discovery 640 headset will provide 15 hours of talk time when used with the AAA battery charger (included).  A fully charged headset will provide 5 hours of talk time, and the battery charger offers another 10 hours of talk time. However, if the headset is attached to the AAA battery charger while holding a charge, it will drain the AAA battery more quickly, resulting in less total talk time. The AAA battery is also being depleted (slowly) whilst in the AAA charger.  To ensure maximum talk time, be sure that your headset's charge is depleted before you attach the AAA battery charger. Discovery 645: The Discovery 645 headset will provide 9 hours of talk time when used with the AAA battery charger (included).  A fully charged headset will provide 3 hours of talk time, and the battery charger offers another 6 hours of talk time. However, if the headset is attached to the AAA battery charger while holding a charge, it will drain the AAA battery more quickly, resulting in less total talk time. The AAA battery is also being depleted (slowly) whilst in the AAA charger.  To ensure maximum talk time, be sure that your headset's charge is depleted before you attach the AAA battery charger.
