The larger contact is the neg. (-) terminal and the
smaller contact is the pos. (+) terminal.
Insert the contact end of the battery first, making sure
the large terminals are aligned with the large contacts in
the compartment.
Depress the batteries slightly to allow the door to rotate
and close. The battery contacts are spring loaded to

CAUTION: Lithium batteries will expand and
swell if allowed to go into a deep discharge.
Be sure to remove lithium batteries as soon
as possible after they are depleted. If lithium
batteries are allowed to fully discharge while
still inside the battery compartment, they will
be very difficult to remove.
Stuck lithium batteries can be avoided by
removing the label wrapping around the
battery before use. This will allow the battery
to swell but will still leave enough room in
the compartment for the battery to fall out
normally.
