Notes on charging
Life span of the built-in lithium ion battery
The rechargeable battery has a life span. As time passes and the number of times that the battery is used increases, the
capacity of the rechargeable battery slowly decreases. When the amount of time that the battery can be used seems
significantly shorter, despite having been fully charged, contact your nearest Sony dealer.
The life span of the rechargeable battery differs depending on the usage, environment, and storage method.
Caution
When the speaker detects a problem for the following causes while charging the battery, it will stop charging even if charging is
not completed, and the CHARGE indicator flashes quickly in orange.
Ambient temperature exceeds the range of 5 °C – 35 °C (41 °F – 95 °F).
There is a problem with the battery.
Note
Charging time varies depending on battery usage conditions.
Charge the speaker in an ambient temperature of between 5 °C and 35 °C (41 °F and 95 °F).
The speaker becomes warm during charging. This is not a malfunction.
If the speaker is not used for a long time, it may take longer to charge the battery.
Avoid exposure to rapid temperature change, direct sunlight, moisture, sand, dust, or mechanical shock. Also, never leave the speaker in a car
parked in the sun.
A speaker that is in use can be charged if it is connected to the USB AC adaptor, though the CHARGE indicator does not light up. In this case, it
may take longer to charge the battery depending on the conditions of use. Therefore, it is recommended to turn off the speaker when charging.
