Who has had a leaky battery this year?

Davis,
High on the list of reasons is someone carrying the battery by the wires. The terminal is only soldered in place under the red or black sealant. This allows the same battery to be supplied with various terminations under different part numbers.

We got a battery in the KoP that was shorting...
It wasn't leaking and we couldn't find any reason.

yarden,
Shorting?

[DavisC]

I was definately the only person to handle the battery. Also I noticed it before I had the chance to put any wires on it.

@Yarden- did it just make random disconnectings? That is what the bad terminal battery did (tested it because FIRST refused to replace it).
As an example of the disconnecting, it would get everything booted, but the moment I pressed enable, we lost communication.

Davis,
Was there any damage in the packaging?

Informative discussion. For the last two years we have mounted the battery upright in the robotic with sturdy support around it. Because I don't tug on Superman's head. (Most days.)

This is true; but not necessarily conclusive. We checked the suspected chargers last year for Voltage and Current draw and concluded they were in specification. We checked them at the Troy district event where we were having the issues with leaky batteries. Using new chargers with new batteries this year is inconclusive because we changed two variables, the chargers and the batteries. We would have to be using the old chargers with new batteries in order to be conclusive.
Although not 100% conclusive, the sensible conclusion seems to point to the new batteries received at the Troy district event (may have been damaged in shipment or defective from the factory). What makes it less than 100% conclusive are other potentially unknown factors (charger may have been faulty in an intermittent way - happened when we were not testing?).

The mks have never leaked for us though the black tops we have had problems with. When they start leaking take them to a local scrapyard and use the money to buy new mks. Handle with chemical proof gloves to avoid chemical burns
