I'm not sure if it is around in another topic, I couldn't find anything anyway,

I'm looking to find out if there is a difference in the batteries for the stse and the xts, xtsc lines.I have one I replaced from the a mach 1 which is the 1/2AA 3.6v.

The others while looking at them still soldered on the boards I can't see if they are 3.6v or something else, of course they are labeled on the side closest to the board.

Any help is appreciated.

PM sent with contact information.

thanks again Ed, he was very helpful.

Also the batteries are the same.
