What you need to know about Li-ion batteries

Do not use hot air or metal rods to remove the Speaker Li-ion battery, it is very dangerous.

The Li-ion battery will enter a sleep state after being left unused for a long time. At this time, the capacity is lower than the normal value, and the use time is shortened. However, the lithium battery is easy to activate. For optimal performance, please calibrate your newly installed battery: Do this by draining your battery below 5%, then charge uninterrupted to 100%, and repeat at least 2-3 times.
