Save yourself a trip to Radio Shack. They haven't stocked that part for
several years. That is what I was told when I went looking for it about
3 years ago. That's why I had to take the battery to Interstate, and
have them put leads on a new one.
I do not know what the voltage is, but apparently Interstate could
cross reference the number on the original battery to come up with
something that will work.
I could not find the part number in the 202 manual. There is a parts
list though,, so I may have overlooked it.
