Batteries
The H-32 is designed to work with a replaceable 1800mAh Lithium-ion battery pack.
Under constant use the battery pack should last about 4 hours before a battery swap or
recharge is needed. When the H-32 is docked into the cradle or when the H-32 battery
pack is inserted in the charger slot of the CRD32 battery charging will take about 4
hours and 30 minutes. When charging is done by the USB cable charging of a depleted
battery can take up to 8 hours.
