The Single Slot USB cradle charges the MC55’s main battery and a spare battery simultaneously.
The MC55’s Charging/Battery Status LED indicates the status of the battery charging in the MC55. See Table 1-1
on page 1-6 for charging status indications.
The spare battery charging LED on the cradle indicates the status of the spare battery charging in the cradle. See

The 2400 mAh battery fully charges in approximately four hours and the 3600 mAh battery fully charges in
approximately six hours.
Charging Temperature
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). Charging is intelligently controlled by the
MC55.
To accomplish this, for small periods of time, the MC55 or accessory alternately enables and disables battery
charging to keep the battery at acceptable temperatures. The MC55 or accessory indicates when charging is
disabled due to abnormal temperatures via its LED. See Table 1-1 on page 1-6 and Table 2-1.
