Battery pack
●
Use in very hot or cold environments, for example, when left in an automobile
with the windows closed in summer, will cause the battery capacity to drop
and shorten the available battery usage time. This will also shorten the
battery pack's service life. Try to use the battery pack as far as possible at
room temperature.
●
When the battery pack is not to be used for a long time, remove the battery
pack from the product and store it away from hot and humid places.
●
Charge the battery before using the product for the first time after purchase,
or if you have not used the product for a long time.
●
The battery pack is a consumable item. If the performance of a battery pack
does not recover after charge, the battery pack is at the end of service life,
so buy a new one of the specified type. Note that the length of service life
varies depending on the usage condition, etc.
●
Do not discard battery packs together with regular trash. Please cooperate in
the collection of used battery packs to protect the environment and
effectively use resources. au shops and other retailers collect used battery
packs.
●
Battery packs sometimes swell up as they approach the end of their service
life. This is due to the properties of lithium-ion batteries, and is not a problem
in terms of safety.
