Battery Notices
The MT680-AMWTAG is equipped with a Lithium-Ion battery. But, after extended storage
periods, the MT680-AMWTAG may not start without an external power source due to battery
discharge. In this case, connect the MT680-AMWTAG to the power cable and recharge the
MT680-AMWTAG for about 12 hours to charge the battery to full capacity.
The battery supplies operational power to the MT680-AMWTAG for approximately two hours
(depending on hardware configuration and with limited backlight use) or provides backup data
for three days when there is no external power source.
Battery Charge Notice
It is important to consider the environmental temperature whenever the Lithium-Ion battery is
charged, which is most efficient at room temperature or in a slightly cooler environment. It is
essential that batteries are charged within the range of 0°C to 45°C (32ºF to 113ºF). 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 deplete due to build up of internal resistance. If this happens they will require recharging
prior to use. Lithium-Ion batteries may store at temperatures between -20°C to 60°C (-4ºF to
140ºF), however they may deplete more rapidly at the warmer end of this temperature range.
It is also recommended to store batteries at room temperature.
