BATTERY CARE GUIDE
Your speaker comes equipped with a high-performance lithium-ion battery
and the life span is aected by charging and usage. Follow the guidelines
below to keep your battery in great condition for as long as possible.
• Avoid using fast chargers if possible. Fast charging
causes stress on the battery and will degrade it.
• Avoid charging the battery when it is already full or letting it drain
completely. Try keeping the charge between 30% and 80%.
• If the speaker is stored for a long time, do so with a half-
charged battery and in a cool, dark, and dry place.
• Do not use or charge the speaker in hot and unventilated places, 45°C/113°F
and above, such as in a parked car or by a window in direct sunlight.
• Avoid charging the battery at low temperatures, below
10°C/50°F and using the speaker below 0°C/32°F.
• Avoid strong mechanical shocks such as dropping the speaker
on hard surfaces as it might damage the battery.

settings, excluding any firmware updates.
Note: This will delete all user settings meaning the speaker will need to be
set up again.

o and the speaker restarts.
