2.1.2 Battery Use and Maintenance
CAUTION: To en-
sure optimal per-
formance, the battery
should be fully charged
before its initial use.
The ES210 Mesh Point is equipped with a 7.4 volt, 4 amp-
hours (29 watt-hours), lithium ion polymer battery. The battery
can power 5–8 hours of Mesh Point operation, depending on
the specific power requirements of your deployment. It is
specified to operate for at least 500 charge cycles.
When the Mesh Point is powered on and is not receiving
external power, battery power is automatically switched on.
The Mesh Point will automatically power off five minutes after
reaching a
Low Battery condition (below 6.3 volts), if external
power is not supplied first. A
Low Battery condition is indicated
by the top-panel
Battery LED slowly flashing green (complete
Battery LED indications are described in Section 3.1.1).
