Power Supply
The MX3Plus uses two batteries for operation.
A 1900 mAh replaceable Lithium-Ion (Li-Ion) battery pack. The battery pack recharges while the computer is in a powered
cradle or when connected to the optional external power sources. The main battery can be removed and inserted in the MX3
labeled Multi-Charger which simultaneously charges up to six battery packs in four hours.
An internal 50 mAh Nickel Cadmium (NiCd) backup battery. The backup battery is recharged directly by the main battery when
it is in the mobile device. Full charging of the backup battery may take several hours. The recharging of the backup battery is
automatically controlled by the operating system. The backup battery must be replaced by qualified service personnel.
Optional AC adapters are available – external AC power supplies (US and International) and a cigarette lighter adapter.
