RFID TAGS…
Are you getting a pile of ST-410-
108 and -118 radio frequency identi-
fication (RFID) tags in the corner of
your warehouse because of incorrect
battery storage?
Could be the tags are just fine
and the batteries inside them are
the problem.
Since you can’t turn the tag on
or off, the battery can drain
when the tag is in long-term
storage. To prevent this, the bat-
tery should be reversed and rein-
serted into the tag before it is put
in storage. This stops a continu-
ous drain of battery power.
When the tag is removed from storage and ready to be used, the battery
must be reversed and put right. If you don’t, you’ll think the tag is busted
and pitch it into that growing pile in the corner.
If a tag is not working, make sure the battery is in right. If you are put-
ting the tag in long-term storage, reverse the battery so it won’t drain. No
need to do that for short-term storage. The tag has a sleep mode that pre-
vents energy drainage.
Since you are working
with a lithium-sulfur
dioxide battery, keep
safety in mind. The gas
is toxic and the battery
should be handled with
care so it does
not rupture.

8.
Position the solder tabs on the new battery so that
they are parallel with the cover. If necessary, remove
the plastic sleeves from the wire and trim it back to
expose enough wire to do the solder job. Replace the
plastic sleeves.
9.
Hold the wire perpendicular to the solder tabs.
Then solder the wire in place using 60/40 rosin core
solder only. Cut off the excess.
10.
Connect the positive lead to the red battery
terminal and the negative lead to the black battery
terminal.

Put the KAB assembly
back in place and tighten
down the screws
to secure it to
the SHTU.

The ST-412-U1-001 tags might also be piling up for the same basic reason,
but the problem is solved a little differently. The 412 tag is always kept in its
tag mounting bracket in either the “ON” or “OFF” position. The status of the
412 can be verified by checking to see whether “ON” or “OFF” is visible
through the hole in the tag mounting bracket. To conserve battery energy, the
tag should be placed in its “OFF” position anytime it is not being used.

away for awhile? If
“ON” shows here…
