So you intelligent gentleman are equating a battery with a loaded gun.....wow. So are the harbor freight batteries known to be bad, or is everyone just jumping on the BCR band wagon now? How long ago was there a concern that BCR might harm the charge circuit and ruin a board?
6 batteries at $5 is about 6 x 5 years of service or 30 years. 1 BCR is $30 and X years? Will those capacitors last 30 years? Maybe the gentleman figures he only has 20 years left running trains.
It is economics and easy of maintenance otherwise 6 or a half dozen. G
