Battery Notices
The MT380 is equipped with a Lithium-Ion battery pack. After extended storage periods, how-
ever, the unit may not start without an external power due to battery discharge. In this case
connect the unit to the power cable and recharge the MT380 for about 12 hours to charge the
battery to full capacity.
The battery supplies operational power to the MT380 for approximately one hour (depending
on hardware configuration and with limited backlight use) or provides backup data for three
days when there is no external power connected.
Battery Charge Notice
It is important to consider the environmental temperature whenever the Lithium-Ion battery
pack is charged. Charging is most efficient at normal room temperature or in a slightly cooler
environment. It is essential that batteries are charged within the stated range of 0°C to 50°C.
Charging batteries outside of the specified range could damage the batteries and shorten their
charging life cycle.
Storage and Safety Notice
Although charged Lithium-Ion batteries may be left unused for several months, their capacity
may be depleted due to build up of internal resistance. If this happens they will require
recharging prior to use. Lithium-Ion batteries may be stored at temperatures between -20°C to
70°C, however they may be depleted more rapidly at the higher temperature ranges. It is rec-
ommended to store batteries within normal room temperature ranges.
