Who has had a leaky battery this year?

[tsaksa]

We had two batteries leak this year with no signs of mechanical damage. This was a small amount of acid appearing near the two rectangular indentations near the terminals on top of the battery. We do not think they were over charged, and we were using the standard single battery chargers sold by Andy-Mark.

I hear via rumor that at least a few other teams at our regional had at least one leaky battery this year as well. These were the first two leaky batteries our team ever had, and according to the safety folks I spoke with at regionals battery leaks have been fairly rare in the past few years. Hopefully we are not looking at a systemic problem or a bad lot of batteries, but I am curious to hear from other teams that may have had leaking batteries this year. If you did have a leak, did you notice the location or any other significant conditions?
