Looking for current # to replace a Size Z  battery (Panasonic brand) It appears to be same diameter as a double AA  and about half the length of a AA . Used to power an LED on a Track Master  G Scale track cleaning car!

Stan, he says it's powering an LED.  As to why you need an LED on a track cleaning car, that's a whole different question.

OK I think I'm being picked on!! LOL  Well it is an "N" battery depends on how you hold the battery! I will take a photo of the car and post!  As to why you need a LED on a track cleaning  1 because it was an available option and  2 it looked cute.

If it really is a 1.5V N battery (not to be confused with the similarly sized 12V A23 battery ), then it would need some kind of voltage step-up circuit to drive an LED.

My curiosity was why such a small battery size given the size of the G scale car.  Seems a "full-size" 1.5V AA or AAA would easily fit and be less expensive and more easily found.  I await the pictures!

BTW, I realize it's been established that we're indeed dealing with an "N" battery...but there is a "1/2 AA" Lithium variant at 3.6V which would be a good starting voltage to drive a ~3V white LED.  That is, it is cheaper and takes less circuitry to reduce 3.6V to ~3V than to raise 1.5V to ~3V.

Stan See Photos below!!  $3.99 for the new N battery's!
