Harman Kardon Onyx Studio 1 Wants to Live Only Uses Adapter Doesn't Want to Use Batteries

The harman kardon onyx studio speaker has been sent again, but it's only the mainboard and the twitter speakers. The damage does not want to use the battery, I think the owner of the battery has dropped it but after buying a new battery it turns out to be the same. After checking, it turns out that the problem with the charger ic is a little short but burdens the performance of the battery.
