Batteries in my Audioquest Colorado RCA interconnects


The box attached to the cables read: aq DBS 72v

It takes (6) 23ae 12v batteries in each box per cable. I judiciously replace batteries in remotes etc. yearly like checking the fire alarms. These batteries, which I have failed to register, have been in / attached to these cables for 8 years plus however long they were in prior to my purchase. AND they did not leak. AND when I push the little button on the box on the cable the little green light turns on. 

Would that be pure lucky and amazing?

Also, can anyone tell me if I am using them in the best way: They connect the output of the tube pre-amp to the input of the tube main amp. My thinking is that is where the most current / possible noise would exist. But looking for advice. As these are my most expensive (I think best quality) interconnects I own.

Audioholics did a tests of the audioquest speaker cables with batteries, and no surprise, the measured worse with batteries in than out. 

@cinqcepages -

     While you have the batteries out: check them with a multimeter, for full, remaining voltage.

     After that many years, even without a load, batteries can lose output potential.

     No telling how minimal a voltage might still illuminate that test light.

     Unless your batteries are still at their peak; a test with and without, would not be legit.

@mceljo I was and am happy. Just surprised that a: I didn't realize they had batteries and B: that they didn't leak after so many years! But what you say is correct.

@jasonbourne52 I kind of thought that. I bought them at an auction clearance of a store going out of business. Got them for $100. So I used them. But I had my doubts about the technology.
