Re: Battery failures?

We have had 4 fail within the last year. 1 at champs last year overnight began leaking. We quickly got it contained and cleaned up the next morning when we found it.

During build season we were trying to fit a battery into the practice robot for locating the battery mount and it wouldn't fit, discovered that the battery had started to swell.

After that I bought a battery beak and we have been checking our batteries and pulling the ones that test fair out of service. We plan to use this to periodically check the batteries and track the data.

At QCR last weekend we lost 2 batteries that tested good but then immediately dropped voltage and now test bad. They were both older batteries, maybe 2010 competition season.
