Bad BCR battery

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.  

Hey thanks for the reply !!  where do I find the charging circuit ??

Trace the wires from the 9V battery plug back to the board it's attached to. And therein lies your charging circuit.

Do you have to replace entire board or is this something that plugs into the board??  Thanks

Your symptoms suggest the charging circuit is bad on the board.  Sadly, for 5V boards, this is usually a death sentence for the board as repair is usually not possible.  The fact that it kills the batteries quickly and also a BCR doesn't work all point to the charging circuit as the culprit.
