Hi guys !!  I have an MTH pennsy SW 8 proto 1 switcher !!The engine quit working so I had the boards replaced and engine was returned with MTH green recharge battery!!  back in June I hosted TCA  home layout tour one evening!!  A few days prior to tour I checked this engine to make sure it was running  perfectly  To my dismay the engine was dead !!  I quickly went out and bought the $10.00 energizer lithium battery ( guaranteed for 10 years ) put it in switcher and everything worked fine during the TCA TOUR !!   the next week the battery was dead again ???  I powered engine up for 5 minutes and it started to work again ??  This battery goes dead on a weekly basis !!   I reinstalled a BCR last nite and let engine sit @ 20volts for 10 min and nothing happened ??   Can BCR go BAD ??  I reinstall Energizer battery and after about 6-8 minutes all the sounds returned back to normal ?? any ideas as to what is going on ??    Thanks   Gary

Back when I was running earlier Proto systems, I installed BCR's in everything.  They should only need to charge up for a minute or so.  Perhaps, your charging circuit is bad.   I'd start by checking the actual connection to the BCR/battery.  I recently noticed that I have one that is beginning to separate on the positive side.
