I have a model 890TT microphone that needs a new battery. Are these still available and can I get them from a electronic parts house? Any information that you can supply me with would be appreciated.
The Shure part number for this battery is 80A455. As of March 2001, Shure Parts has this item in stock. Call 800-516-2525 to purchase this battery.
If you prefer a commercial alternative, the battery is made by Sanyo, part number CR2032-P5-1. It is a 3 volt lithium battery rated at 180mA hours or greater. It has two leads and is designed to be soldered onto a circuit board.
