11.7 Storing the Batteries
11.7.1 Storing Rechargeable Lithium-ion Battery
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.
11.7.2 Storing AA Batteries
If you remove undepleted AA batteries from the TD60 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 TD60.
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).
