Re: First: 2008 Batteries are D-Y-I-N-G.

I've been doing FRC for 8 years, and without a doubt, the Exides we used 01-06, we're so much more reliable. Last year, by the time we got to Atlanta, our batteries (unknown to me at the time) were so unreliable. I know I'm not a battery expert, but I thought I knew enough about keeping them charged, marked, and tested to know that we can use them on our robot. Unfortunately we lost two matches due to a low battery problem. We all blamed our battery crew - they swore it was a well charged battery - and later we determined that two of the batteries will reading 13+ Volts and then drop to 6-8 Volts within seconds of the start of a match. Very frustrating. The problem definitely got worse as time went on - most likely to violent robot action/crashing (or a student dropping/rough handling).

I'm glad to know I'm not the only one unhappy with the MK batteries from last year.
