Rechargeable AAA Battery pack as packaged with DS-4000 and DS-5000 Digital Voice Recorders.

 

The BR403 can also be purchased as an accessory, for use with the DS-3300 DVR.  Note that, for best recharging results, the D-7AC Mains Adaptor should also be purchased if you choose to use the BR403 battery pack with the DS-3300 DVR.

 

The BR403 Battery Pack has superseded the BR402, which has been discontinued.
