So, the moral of the story is that old batteries can be really dead - but a few could still be good? It also seems that there is a sharp difference between "good" and "bad" batteries, and it will be obvious after using it in a robot for just a minute. I'd be curious to know where the rest of the 2006 batteries fall in on the scale. Were they already deemed bad and discarded?

Yes, the rest of our 2006 batteries had already been taken to the recycling center before the start of the 2011 season. Interestingly enough, none of our 2008 batteries made it to 2011, either, even though 2 of the 4 batteries from 2005 and 3 of our 4 batteries from 2007 were still in the running.

For what it's worth, our battery testing for the 2013 season is ongoing, and we still have one 2005 battery (our rookie year) that is hanging in there, although we've had to dispose of our other remaining 2005 battery and one of the 2007 ones. It really makes me wonder what specific events in these batteries histories have led to early deaths on some, yet long lifetimes on others -- we've generally used them all about the same as one another. I suppose maybe some of them have suffered from isolated instances of rough handling leading to earlier deaths.

Well, the 2008 batteries did pull double duty all season long!

Thanks for sharing Coach Streeter!
