cap. Use the alignment tab on the battery holder (shown in
step 4) and the arrow on the logger housing as a guide as
you fit the small tab in the mounting end cap into the small

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.
