Warranty does not cover this type of damage.
2.3.2. Battery Life
The Minimate Pro battery life depends on current draw, aggregate sample rate, battery longevity,
and ambient temperature. Review the following information to determine an estimate for battery
life.
The nominal battery life for a Minimate Pro unit running in monitor mode is 10 days, at a sample
rate of 1024, when in an environment of 25° C (77° F). If the ambient temperature drops to -20° C
(-4° F) the battery capacity will also drop to approximately 80% or 8 days. At --40° C (-40° F) the
capacity is approximately 50%.
Record Number of Recording Days at

Waveform 10 8 5
Histogram 3.2 2.5 1.6
The nominal life expectancy of the battery (>70% of initial capacity) is >300 cycles. Li Ion
batteries do not experience a memory problem if left on charge all the time. The typical charge
retention (>80% of initial charge) is approximately 3 months over a temperature range -20° C (77°
F) to 45° C (113° F).
NOTE: Depending upon activity on the Ethernet connection the number of record days could be
reduced by 50%. We recommend connecting a unit to the supplied AC adapter or an external 12
VDC power supply for
Histogram and Histogram Combo Record Modes .
LOW TEMPERATURE WARNING:
The internal batteries will not be charged if the ambient temperature is below 0
0
C (32
0
F) or above
45
0
C (113
0
F). However, the unit will continue to operate, drawing power from either the internal
battery or the external power source, whichever is higher. As a consequence of this, if the unit is
operated below 0
0
C (32
0
F) for an extended period of time, the batteries may eventually become
depleted, and the unit will be totally reliant on the external power source.
