I have posted this picture earlier in the 787 thread.
It shows a brand new spare Lithium battery for a SART (Search And Rescue Transponder). It was not being charged, it was not being discharged, there were no pinched wires and the manufacturer could not explain why it ignited, but it did. The damages to our store room and office was incredible from this small battery, probably 1/3 of the size on an IPERB/ELB. To protect the battery it had a solid end cap screwed on, see the tops of the remaining batteries, this was blown off and the battery went like a projectile around the store room denting fairly strong steel shelfs and leaving scorched painted steel in its wake before it came to rest with enough energy remaining to burn into the protective casing of the battery it is resting against.
These batteries scare me.
