Rechargeable Li-ion Battery Characteristics
Understanding the properties of the rechargeable Li-ion battery will allow you to optimise 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 while the rechargeable Li-ion battery is installed and charging may accelerate
the battery's deterioration. If using the P-touch when the rechargeable Li-ion battery is installed,
disconnect the AC adapter.
• If the P-touch will not be used for longer than one month, remove the rechargeable Li-ion battery
from the P-touch, 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 while the Li-ion battery is charging, that part of the P-touch
may feel warm. This is normal, and the P-touch may be used safely. If the P-touch becomes
extremely hot, discontinue use.
