14.7 Storing the Batteries
14.7.1 Storing Rechargeable Lithium-ion Batteries
When storing batteries, make sure that the battery terminals do not come into contact with
metallic objects.
If you need to store the batteries for an extended period of time, place the batteries in a
cool, dry place (ideally at 15°C or 60°F) with a partial charge of about 50% capacity (two
LEDs illuminated). Storing batteries in a cool place can slow the aging process.
Stored batteries should be charged to about 50% of their capacity every six months. The
battery should be fully charged prior to first use.
NOTE
•
Remove the lithium-ion battery from the device if the device is not used for a
prolonged time (for example, several weeks), and keep the device in clean place
to avoid the dust or liquid entering the battery compartment.
•
Storing batteries at high temperatures for an extended period of time will
significantly shorten their life expectancy.
•
Do not store the batteries in an environment above 60°C (122°F) or lower than -
20°C (4°F).
14.7.2 Storing AA Batteries
If you remove undepleted AA batteries from the telemetry monitor and need to store the
batteries, keep the batteries together as a set for later re-use so that all batteries will have
the same level of remaining power.
Do not store disposable AA batteries by leaving the batteries in the incorrect polarity
position in the telemetry monitor.
NOTE
•
Replace the AA battery tray on the battery compartment after removing the AA
batteries.
14.8 Maintaining the Rechargeable Lithium-ion Battery
Take care of the rechargeable lithium-ion battery once you receive a new battery for use.
The following table describes the battery maintenance activities and recommended
frequency.
