" BCR" ( B attery C omponent R eplacement) produced by " J and W Electronics " for your Lionel* and M.T.H. engines. It is a permanent replacement circuit for the 9 volt battery.
If you store or display your engines and decide to run them, you may find that the M T H engine will not operate, or the MTH and Lionel sound systems will not shut down properly because of a dead battery . After the " BCR" has been installed, you simply apply power to the tracks for one minute in the reset position - (first "neutral" position when the engine is turned on)- and the engine will operate again, just like having a fully charged battery.
This amazing device allows you to store or display your engines and never need to charge or replace your battery to operate them. After one minute of applying power, at 10 volts or more, to activate the " BCR " , the engine will be able to fully operate. No longer do you have to replace the battery or be concerned about the battery leaking and damaging your engine. The " BCR " can be left in the engine indefinitely . After turning the power off to the track, the "BCR" will hold a charge for about 3 hours, depending on the engine. If you have not operated the engine in 3 hours, power up the engine in the reset position, for one minute at 10 volts or more.
