I don't know which one you bought from Dai Le. First of all, your stereo must be equipped with a charger, just like the charger on the second right below.

Find the power port as shown below, plug it in and charge it, and you can continue to use it.

But if it still takes less than a few minutes after being fully charged, it involves 1. The service life of the battery is up. You need to find a new one from Dyle. If the charging circuit is broken, you need to find Dai Le to repair it.
