Yes, it has separate rechargeable backup battery 25mAh. It works only when you remove the Main Battery and it will last for about 20 to 30 minutes, assuming it is fully charged. Note 1: Before using your Device please make sure to charge your i-mate™ JAM for at least 8 Hours for the first time (this is required for the Backup Battery to fully charge).
