WestMDRR,
It is really a Super Capacitor named BCR, I have never worn one out, mine have been in for over 10 years now, once in a while you can get a faulty one like Gun Runner John purchased. Take the Battery out and replace it with the BCR, they last almost for ever. The draw back is you must let your engine in neutral setting on your powered tracks, for about 5 sec each time you start your engine, especially if the engine has been off the tracks for a while, to charge the BCR for usage. Further on initial installation, let the engine set for about 10 minutes with the track powered up, and all works perfectly from that point on. I use them in all my P2 engines and IMO they are a mandatory item for all P1 engine. I know Marty is not overly fond of them, it's about the only thing we disagree on, when it come to our Hobby.
