Battery failures?

[JamesCH95]

At the CT regional team 95 experienced two battery failures. The first was a total dead short or broken tab. The battery failed a load test and measured around 0.001-0.005V with a multi-meter. No chargers or connectors were wired backwards and there was no obvious issue with any of the charging ports. After our final match the battery came out with acid slowly spraying out of the cap/seal on the top of the battery.

Thanks a million to 195 for giving every team a spill kit with a box, gloves, and baking soda. We used ours to keep a potentially dangerous situation contained.

Now, both of these batteries were new in 2013, and are the only two battery failures I've experienced first-hand. It was also the first time we used these chargers from AM.

Have any other teams seen failures like this? Related to 2013 batteries or those chargers? Could there be another cause?

Thanks in advance.
