Backup Battery Adapter allows the use of a 9 volt battery to power scanners instead of the rechargeable battery pack.
Great for emergency use when the rechargeable pack dies or you forgot to charge it up.
Works on all scanners using the BP-120 type battery including the Sportcats SC200, SC180, SC150(yellow and black), BC220, BC230, BC235, BC245, some Radio Shack models and several other Uniden models.
Replaces the BP-120, BP180, BP-250 and other similar 4.8v Uniden scanner battery packs using this plug.
Voltage regulator prevents scanner damage from high voltage.
9 volt battery NOT included.
