Flat A123 Cells- When?

[marzac2]

WHY does the battery description say it CAN puff?

At the bottom of the description, it gives warning for car/boat users to be careful not to over discharge the cells or they will puff and be damaged...

They are talking about massive over discharging... below allowed voltage not normal use, don't go to 0.0v and cause a short and you should be fine :) LOL

Deeply over-discharging these packs could cause cell(s) to reach 0.0V or even negative voltage. This could short circuit it and cause it to puff.

How the hell can you get a cell to reach - voltage????
