Vintage Simmons Drums (UK) Users Group

Hi there,

I'm new to the group, and new to Simmons drums in general.  I just recieved an SDS7 
from my girlfriend's uncle over the holidays and I'm in the process of checking it out 
to see if/how everything works.  I finally got around to trying to program sounds 
today, and it looks like the internal battery died as nothing will commit to memory.  I 
read through some previous posts on this and managed to find where the battery is.  
Does anyone happen to know the model number of a replacement battery I could buy 
from a US company?  Also, could I find this at my local Radio Shack, or is it difficult to 
track down and I'd be better off getting it online?  Thanks for any help!

Justin
