Battery Information
The mote uses two 1.2 V rechargeable NiMH batteries, charged
by the built-in solar panel. The quality and quantity of solar
light can affect whether the battery is sufficiently charged to
last through the night and cloudy periods. Make sure the mote
is placed in a location that will receive several hours of sunlight
each day. If the mote does not receive enough sunlight to
recharge the batteries, the battery life is estimated at 3–4
months. When batteries are regularly recharged, expected
battery life is estimated at 3–5 years. Battery life varies based
on the ambient temperature where the mote is deployed, the
logging interval, the number of tripped alarms, and other
factors. Deployments in extremely cold or hot temperatures
can impact battery life. Estimates are not guaranteed due to
uncertainties in initial battery conditions and operating
environment.
Mote operation will stop when battery voltage drops to 1.8 V.
Mote operation will return if the battery recharges to 2.3 V. If
the batteries are unable to be recharged, replace them with
fresh rechargeable batteries.
To replace rechargeable batteries:
1.
Open the mote door.
2.
Remove the old batteries and install the new ones
observing polarity.
3.
Make sure the solar panel cable is plugged in.
You can use two 1.5 V lithium batteries (HWSB-LI) for operation
at the extreme ends of the mote operating range. Lithium
battery life is an estimated at 1 year, but varies based on the
ambient temperature where the mote is deployed, the logging
interval, the number of tripped alarms, and other factors.
Estimates are not guaranteed due to uncertainties in initial
battery conditions and operating environment. When using
lithium batteries, you must disconnect the solar panel cable
because the batteries will not be recharged.
To install lithium batteries:
1.
Open the mote door.
2.
Remove any old batteries and install the new ones
observing polarity.
3.
Push in the side tab of the solar panel cable connector and
pull the connector out of the cable port.
4.
Place the connector in the slot on the inside of the mote
door. Make sure the solar panel cables are tucked inside the
door so that they do not interfere with the interior seal
when the mote is closed.
WARNING:
Do not cut open, incinerate, heat above 85°C
(185°F), or recharge the batteries. The batteries may explode if
the logger is exposed to extreme heat or conditions that could
damage or destroy the battery cases. Do not mix battery types,
either by chemistry or age; batteries may rupture or explode.
Do not dispose of the logger or batteries in fire. Do not expose
the contents of the batteries to water. Dispose of the batteries
according to local regulations.
