Rechargeable Li-ion Battery
Tips on Using the Rechargeable Li-ion Battery
• Charge the rechargeable Li-ion battery before use. Do not use it before it is charged.
• The rechargeable Li-ion battery charging can take place in 5°C/41°F to 35°C/95°F
environments. Charge the rechargeable Li-ion battery in an environment in this temperature
range. If the surrounding temperature is out of this range, the rechargeable Li-ion battery will
not be charged, and the battery indicator will remain lit.
• If the P-touch labeling system is used when both the rechargeable Li-ion battery is installed and
the AC adapter is connected, the battery indicator may turn off and charging may stop even if
the rechargeable Li-ion battery has not been fully charged.
Rechargeable Li-ion Battery Characteristics
Understanding the properties of the rechargeable Li-ion battery will allow you to optimize its
usage.
• Using or storing the rechargeable Li-ion battery in a location exposed to high or low
temperatures may accelerate its deterioration. In particular, using a rechargeable Li-ion battery
with a high charge (90% or more) in a location exposed to high temperatures will considerably
accelerate battery deterioration.
• Using the P-touch labeling system while the rechargeable Li-ion battery is installed and
charging may accelerate the battery's deterioration. If using the P-touch labeling system when
the rechargeable Li-ion battery is installed, disconnect the AC adapter.
• If the P-touch labeling system will not be used for longer than one month, remove the
rechargeable Li-ion battery from the P-touch labeling system, and then store the battery in a cool
place away from direct sunlight.
• If the rechargeable Li-ion battery will not be used for a long period of time, we recommend
charging it every 6 months.
• If you touch a part of the P-touch labeling system while the Li-ion battery is charging, that part
of the P-touch labeling system may feel warm. This is normal, and the P-touch labeling system
may be used safely. If the P-touch labeling system becomes extremely hot, discontinue use.
