Battery care

Your speaker comes equipped with high-performance lithium-ion batteries and the battery life span 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.
