I have two Radio Shack NICAD batteries for one of their cars that provide power for my lgb Mgul. Now that I’m bringing it out of retirement it is ready for new batteries. Are their batteries still the best choice?
Probably not. Try Batteryspace.Com - they have good pricing. You also have the choice to change to some other style if you want. I’ll assume these are 7.2V packs wired in series to give you 14.4 volts at the loco throttle input.
Ex. Radio Shack manager 
Doug; There are several electonic wholesalers that will set up a pack for you. That is how I got a set of 9.2 or is it .3 , any way they are Nicll Metal Hydrid (spelling) for my Caboose markers and thsy work just fine. You might try the TOC as he has batteries in the size and ranges you will want.
