WARNING
The temperature rating for the device may exceed the usable
range of some batteries. Alkaline batteries can rupture at high
temperatures.
Contact your local waste disposal department to properly
recycle the batteries.
Alkaline batteries lose a significant amount of their capacity as
the temperature decreases. Use lithium batteries when
operating the device in below freezing conditions.
Long-Term Storage
The normal long-term decrease in the charging capacity of
lithium-ion batteries can be accelerated by exposure to elevated
temperatures. Storing a fully charged device in a location with a
temperature outside the long-term storage temperature range
can significantly reduce its recharging capacity.
When you do not plan to use the handheld device for several
months, the battery should be removed. Stored data is not lost
when the battery is removed.
When you do not plan to use the collar for several months, the
battery should be charged to about 50%. The device should be
stored in a cool, dry place with temperatures around the typical
household level. After storage, the collar should be fully
recharged before use.
