Battery care guide

Your speaker comes equipped with high-performance lithium-ion batteries with a life span that is affected by charging and usage. Follow the guidelines below to keep your battery in great condition for as long possible.

Avoid using fast chargers if possible. Fast charging causes stress on the battery and will degrade it.
Avoid letting the battery drain completely or charging it when it’s already full. Try to keep the charge between 30% and 80%.
If the speaker is stored for a long time, it is recommended to charge the speaker to about half-charge and then do a factory reset. Store the speaker in a cool, dark, and dry place.
Avoid using or charging 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 harm the batteries.

Download the Marshall Bluetooth app and select the battery preservation level that best suits you and your speaker.
