logging. Deployments in extremely cold or hot temperatures or
a logging interval faster than one minute can impact battery
life. Estimates are not guaranteed due to uncertainties in initial
battery conditions and operating environment.
To replace the battery:
1.
While pushing down with both thumbs on the back of the
logger, rotate the battery cover counterclockwise until it
stops moving (about a 1/8 turn).
2.
Use the edge below the arrow on the cover to lift it off the
logger.
3.
Remove the battery and place a new one in the battery
holder, positive side facing up. Use a small flat-head
screwdriver to carefully pop the battery out of its holder as
shown.
4.
Inspect the O-ring on the battery cover. Make sure it is
clean and seated properly. Remove any dirt, lint, hair, or
debris from the O-ring. If the O-ring has any cracks or tears,
replace it as follows:
a.
Spread a small dot of silicone-based grease on the O-
ring with your fingers, making sure the entire O-ring
surface is completely covered in grease.
b.
Place the O-ring on the cover and clean off any debris.
Make sure the O-ring is fully seated and level in the
groove and not pinched or twisted. This is necessary to
maintain a waterproof seal.
5.
Place the cover back on the logger as shown, aligning the
notches in the cover with the rounded tabs on the logger
case. The cover will not close properly and maintain a
waterproof seal if it is misaligned.
6.
While pushing down with both thumbs, rotate the battery
cover clockwise until it locks in position under the two large
corner tabs and the two small rounded tabs.
WARNING:
Do not cut open, incinerate, heat above 85°C
(185°F), or recharge the lithium battery. The battery may
explode if the logger is exposed to extreme heat or conditions
that could damage or destroy the battery case. Do not dispose
of the logger or battery in fire. Do not expose the contents of
the battery to water. Dispose of the battery according to local
regulations for lithium batteries.
