Micromate Operator Manual – 721U0201 Revision 6 101
12. BATTERY OVERVIEW
The internal lithium ion batteries are not intended to be replaced by the operator. The Micromate
must be returned to an authorized Instantel repair facility should they need to be replaced. The
Micromate has a tamper label located on the side of the case to prevent it from being opened. Any
attempt to service this product will void any and all warranties offered by Instantel.
The Micromate is supplied with two internal batteries that when fully charged will provide 10 days
of monitoring. An optional third battery can be purchased to extend this to 15 days of monitoring.
Contact Instantel or an authorized service facility for additional information.
12.1. Charging the Battery
The Micromate’s internal battery requires regular charging to maintain performance. Instantel
recommends using the supplied 100-240V 50/60hz AC adapter with a Mini USB output of 5 Volts
and 1 Amp. To charge the battery, plug the supplied AC adapter into the USB connector labeled 5V
DC and the other end into an electrical outlet. Once connected the Charging Status LED will be
yellow indicating the unit is connected to an external power source and the internal battery is
charging. The Micromate will automatically switch and draw power from either the internal
battery or the external power source, whichever has the higher voltage.
When storing the instrument for long periods of time, ensure the battery is charged for at least 24
hours and then disconnected using the power button or the Maintenance Menu.
NOTE: Use of AC adapters that exceed the maximum voltage and current specifications may cause
undue stress on the monitor’s internal regulators. Like all electronic devices, exceeding these
specifications increases the risk of damage and possibly of an accidental fire. The Instantel
Warranty does not cover this type of damage.
12.2. Battery Life and Temperature
The Micromate battery life will depend on such things as the number of events being recorded, the
sample rate, ambient temperature (refer to 12.2.1 Extreme Temperature Operation for additional
information) and the age of the battery. As with all components, batteries will degrade over time
and may not provide the same capacity as a new battery. The nominal battery life for a Micromate
unit is 10 days when running in Waveform mode, recording less than 10 one second four channel
events per day, at a sample rate of 1024 and the ambient temperature is 25° C (77° F). The table
below outlines the approximate affects of the sample rate on the battery life.
