■ Internal...battery
...
• At extremely high or low temperatures, such as if you
leave the product in a closed car during summer, the
capacity of the internal battery decreases and so will
the amount of time it can be used decreases. This
also decreases the lifespan of the battery. Use the
product at room temperature whenever possible.
• After charging the battery, it gradually discharges,
even if you do not use the product. If you do not
use the product for a long time, you should charge
the battery as the internal battery may have
discharged.
• The internal battery is a consumable item. If the
performance of the internal battery does not recover
(e.g. the usable time after each charge has become
extremely short), stop using the battery as it is at
the end of its service life. As the battery is built-in,
you can have it replaced at an au shop/au Style for a
fee. Note that you will not be able to use the product
for a certain period of time. The battery lifespan
varies depending on how the product is used.
• Depending on the use condition, the internal battery
may be inflated as it comes close to the end of its
service life. This is due to the properties of lithium-
ion battery and does not pose any safety risks.
